\"头图\"/
\n

这个问题来得真及时!作为一个从大学时代就开始淘打口 CD 的老听众,对音乐和情绪这个话题确实积累了不少想法。从音乐理论到神经科学我都算不上专业,更多是基于个人体验的观察和思考,说得不对的地方还请各位指正。

\n

PS:文中提及的曲目基本各大音乐 APP 上都能找到。没控制住写得过长,不妨先收藏。码字不易,若读过后喜欢,请点个喜欢

\n

音乐和语言的两条路线

\n

音乐和语言在大脑里也许走的是不同的路线。

\n

音乐处理更像是多通道并行——听觉皮层直接处理音高、节奏、音色的同时,边缘系统(杏仁核、海马体)几乎同步激活。整个过程主要由右脑负责,偏向整体性、直觉性的处理。

\n

而语言处理是序列化解码——必须经过语音识别→词汇提取→语法分析→语义理解这样一步步来,主要依赖左脑的布洛卡区和韦尼克区,得按时间顺序逐步构建意义。

\n

简言之,音乐走\"快车道\",语言走\"慢车道\"。

\n

所以除非本身关注点就在歌词上(比如我们听万青的作品,最有嚼头的就是歌词),日常随意播着扫一耳朵的情况下,旋律确实可能比歌词更容易触动情感。

\n

这里面一个可能的关键差异,我觉得是\"语境\"的表达方式不太一样。

\n

音乐的语境相对直接。你听到的那种忧伤、激昂、宁静的情绪,很大程度上通过声音的物理特性就传达给你了。

\n

而歌词的语境则需要更多层处理:先理解字面意思,再结合上下文,最后才能提取出情感内容。这个认知链条一长,那种瞬间的情感冲击力就容易被稀释。

\n

一个听众的进化简史:从音色开始

\n

下面分享自己的体验。

\n

我的音乐偏好变化是从人声到纯器乐。

\n

大学那阵特别迷爵士女声。那时候网络还不发达,天天吃着《音像世界》\"天碟落地\"专栏的安利去淘 CD。那时被什么打动呢?肯定不是歌词——Diana Krall 唱英语我听不懂,小野丽莎唱日语更听不懂。

\n

琢磨了一下,迷恋的应该是各种有质感和辨识性的音色:

\n

Billie Holiday 那种沙哑磁性,Ella Fitzgerald 的丝绸般光滑,Nina Simone 的深沉厚重,每一种音色就像不同的情感滤镜,即使听不懂歌词,那种忧郁、温暖或激情也能瞬间传达过来。

\n
\"\"
Billie Holiday
\n

为独特音色加成的,是歌手的语感——表面上在唱歌,本质上是利用声音讲故事。这涉及到咬字的轻重缓急、停顿的恰到好处、换气时机的巧妙安排,甚至包括某个音节的微妙处理。

\n

而语感,比唱功更传递情绪。

\n

西方歌手里有两位我认为语感极佳的代表:

\n

首推 Stacey Kent,她咬字极其考究,每个词都像经过精心雕琢,那种轻柔但清晰的发音让人仿佛听到丝绸摩擦的质感。作为少见的现场表现胜过录音棚的歌手,仔细听一下她这首音乐会版本的《It Might as Well Be Spring》,你会发现她在面对乌压压的听众时反而能把普通的句子唱出更多微妙层次。

\n
\"\"
Stacey Kent 这张现场录音特别值得一听
\n

另一位是 Michael Bublé。他对句子的处理继承了 Frank Sinatra 那种对话风格但更自然,就像在跟你面对面聊天一样。他的停顿和重音处理特别有音乐剧感,能让一首爵士标准曲目听起来像在你耳边摩挲的全新作品。

对应到华语乐坛,达到同档次的天赋语感选手有两个代表:孙燕姿和陈奕迅。

\n

孙燕姿不用多说了,她的语感体现在对中文字调的天然敏感上,能把普通话的四声变化和旋律线条完美融合,从不会有字不达意或感觉在“读”的违和感。

\n

重点说下陈奕迅。他无论唱粤语还是国语,都能用咬字吐字的细节变化传达丰富的情感层次。一个简单的转音、一次刻意的颤抖、一个突然的气声处理,都能让整首歌的情感重心发生转移。这种对声音质感的精准又自如的控制,让他即便唱别人的歌也能唱出自己的故事。更重要的是,他的语感不单单体现在运用能力,还透露出很强的私人审美,在华语圈数一数二。

\n

陈奕迅 2014 年这套专辑是我心目中他的最佳
\n

随着年龄增长,慢慢的,我的口味开始转向纯器乐爵士。没有了人声,自然更没歌词什么事了。

\n

但奇怪的是,纯音乐反而更容易沉进去。我有段时间甚至会去比较不同钢琴手的触键质感,这种差异当时比旋律本身更吸引我。

\n

比如 Thelonious Monk 那种有意“显拙”的触键——他的音符有种刺刺的、棱角分明的质感,每个音都像是被不小心砸在键盘上,带着一种不羁的个性;而相比之下,Bill Evans 的触键则轻巧得像羽毛,充满了内省感、空间感和呼吸感。

\n
\"\"
Bill Evans
\n

同样都是从音色中感受情感,相比人声,我觉得器乐音色能让人更微妙地感受到演奏者的个性和情感状态。因为这时候的乐手事实上是个表达欲爆棚的\"哑巴\"——想表达的一切感受只能通过手指在键盘上的动作,通过每一次触键的力度、角度、时机来传达。

\n

在这个层面上,纯音乐可以理解成是情感本身的物理化呈现。它绕过了语言理解的复杂过程,直接用声音的物理特性来雕刻情感。

\n

也许这就是为什么有时纯音乐比带歌词的歌曲更能瞬间击中人心——因为它走的是那条更原始、更直接的情感通道。

\n

节奏:比旋律更原始的情感

\n

下面说个特别容易被忽视的元素——节奏,或者说律动(严格来说两个概念有差异,这里就不细究了)。

\n

节奏是人类最本能的音乐语言。

\n

在远古时代,当第一个人类开始用木棒敲击石头或树干时,那种有规律的声音模式就已经在调动着同伴们的肢体反应。不需要什么文化熏陶,不需要音乐素养,鼓点一响,部落里的人就会忍不住跟着摆动——那是身体将被激发的情感无修饰表达出来了。

\n

记得第一次听《Hotel California》(加州旅馆)1994 年 MTV 不插电现场版,被吸引的不是那段后来人人烂熟于心的吉他 solo,而是 intro 过后 Don Henley 插入的那段手鼓。那种鼓皮微微震动带来的享受很难说清——不是兴奋,不是激动,就是一种\"对,就是这样\"的舒适感。

\n
\"\"
\n

拍打手鼓不像机械节拍器那样精确,而是带着人独有的微妙波动,就像真实的心跳一样会有细微的不规则和扩展收缩时差。

\n

这种\"有机感\"可能正是真实乐器比那些精致的 MIDI 更能触动我的原因。所以直到现在,虽然也会听各种制作特别顶的电音和合成器作品(比如《星际穿越》的 ost,极优秀),但更偏爱的始终是真人演奏的原声乐器。

\n

说回节奏变化,有时它甚至比调性变化更能瞬间转情绪。

\n

比如哈利波特电影那段以音乐盒开场的主题旋律(据说 John Williams 在餐厅吃饭时在餐巾纸上随手写的),大家都很熟悉吧?

\n

后来 Scott Bradlee's Postmodern Jukebox 做过一个爵士改编版本。同样的旋律,当原来 4/4 拍变成跳脱的 swing feel 时,整首曲子瞬间从\"英雄史诗\"变成了\"深夜酒吧\"的氛围。

\n

这种情感转换的感知效率明显比唱一段段词高。

\n
\"\"
《Harry Potter Jazz Variations》(Scott Bradlee)
\n

另一个例子是我特别喜欢的《Por Una Cabeza》。原版是 Carlos Gardel 那种招牌的阿根廷探戈,2/4 拍的节奏紧凑有力,充满了激情和戏剧张力,每一个重拍都像是舞者的脚步在地板上敲击。

\n
\"\"
《Por Una Cabeza》(Carlos Garde 原版)
\n

但有一次意外听到韩国吉他手朴朱元的版本,被惊艳到了。从专辑名《Time Of Gypsy》(吉普赛时光)就能看出,这不仅是将探戈的紧凑 2/4 拍变成古典吉他的自由节拍,还加入了吉普赛音乐那种游牧式的随性律动。这么一改造,整首曲子从\"优雅有力的舞厅探戈\"变成了\"篝火旁的吟游诗人独白\"。两个版本都是单曲循环不会腻的那种,大家可以找来对比听听。

\n
\"\"
《Time Of Gypsy》(朴朱元)
\n

节奏之所以能这么直接地影响情绪,可能是因为它最接近我们身体的生物本能反应。曾和一个做音乐的朋友聊起这些感觉,他的解释颇有启发:各种节奏都是在拓扑心跳、呼吸、步行。

\n

再分得细些,听一首歌时,旋律需要大脑处理音高关系,和声需要预测进行走向,但节奏直接就是速度变化的感知,和我们的生物钟、心跳节律在同一个频道上对话。

\n

由于这种原始性,一首曲子即使旋律弱,只要节奏变化恰当而丰富,也更可能瞬间改变我们的情绪状态。

\n

根源音乐:我们情感旋律的根

\n

原始性是我们情感的根,有的音乐就是绕着根部长起来的。

\n

你大概也遇到过那种虽然完全陌生,但一听到就能马上沉进去、不需要什么知识储备或个人经验作为铺垫的旋律吧——这就是属于你的根源音乐。

\n

我内心深处的根源音乐,是布鲁斯。

\n

不是今天那些越来越偏向炫技、结构复杂的现代爵士布鲁斯或节奏布鲁斯(R&B),而是早期最质朴甚至很套路化的传统布鲁斯。

\n

这种音乐可以说是从棉花田里长出来的,通常只有 19 世纪末 20 世纪初美国南部的非裔奴隶和佃农在棉花田、铁路工地、监狱里干活时才会哼唱。

\n

这些人大多不识字,更没受过什么音乐训练,他们需要的是一大帮子人一歇下来就能凑一起发泄内心的痛苦、思念、希望和绝望,哪怕没唱过跟着哼几次就能加入的音乐。

\n

所以根源音乐最大的的特点是无需文化解码。

\n

就像我们文化中的根源有纤夫号子、采茶山歌、陕北信天游一样,布鲁斯最初也是劳动人民发明出来宣泄情感的。不同的是,它承载的是水深火热世界更深重的历史创伤,因此显得格外向外释放(情绪化),语言免修饰(粗口多),话题包容性极强(管得宽),上到命运(键政)下到生活(八卦),凡事皆可布鲁斯。

\n

如果用我们这里的主流价值观看,这些聚众花式吐槽妥妥都是负能量(甚至有违法嫌疑),但那种\"call and response\"(呼唤与回应)的形式,原本就来自非洲传统音乐和教堂圣歌,一个人唱出痛苦,其他人用和声安慰。

\n
\"\"
《布鲁斯之根》(New World Records)
\n

New World Records 网站上免费分享了一批早期民间录音片段,对最原生态的布鲁斯感兴趣的小伙伴可以听听看(预防针:不悦耳,但保真):

\n

https://www.newworldrecords.org/products/roots-of-the-blues

\n

布鲁斯给人的共鸣感来自其草根互助的基因。呼唤与回应的形式让它从一开始就不是孤独的个人表达,而是集体的情感分担——即使是最深的痛苦,也有人在倾听,有人在回应。

\n

比如 Muddy Waters 的《Mannish Boy》里就能清楚听到这种形式。Muddy 先唱出\"I'm a man\"(俺这么个糙汉子啊),然后吉他和口琴就像其他声音一样回应他,仿佛在说\"嗯呐,你是\"。还有更典型的 Lead Belly 的《Goodnight Irene》,那种一唱众和的感觉就像是一群人围坐篝火,一个人诉说心事,其他人用\"嗯嗯,俺们懂\"\"哎哟喂,可不是嘛\"这样的声音给予共鸣和安慰。

\n
\"\"
《Mannish Boy》(Muddy Waters)
\n

后来和一些乐手朋友聊天——什么路子的都有,古典的、摇滚的、民谣的——那些玩得特别好的,都说自己会经常回去听各种根源音乐,布鲁斯是绕不开的其中之一。

\n

如果要用理论来解释,它用的是人类最古老的声音表达:除了那个呼唤与回应的结构,还有那些能直接触发情感反应的蓝调音符(blue notes)——主要是降三度、降五度、降七度。这些音符在任何文化背景下都能唤起一种说不清的忧伤或渴望,就像某种共性情感的原型。

\n

更有特点的是布鲁斯的不完美。古典音乐理论追求和谐,但布鲁斯故意用那些先不和谐再圆过来的音程连接来体现一开始的自说自话到被理解回应的动态情绪共鸣过程。那种介于大调和小调之间的模糊地带,也正好对应了人类情感的复杂性——既有痛苦也有希望,既有绝望也有坚韧。

\n

从布鲁斯口琴开始情感之旅

\n

好吧,我花了这么多笔墨介绍布鲁斯,就是想安利你试试看。

\n

怎么听呢?推荐从布鲁斯口琴的纯音乐开始。

\n

这种口琴和我们小时候学的复音口琴是两种乐器。复音口琴是 19 世纪从德国发明,经俄国传入中国的,每个音有两个簧片同时发声,追求明亮清脆的音色,很适合演奏《送别》、《茉莉花》这类民歌民谣。

\n

而布鲁斯口琴(通常是十孔单簧片)是老美本土的东西,专为表达复杂情感而生。

\n
\"\"
Hohner 是最知名的专业布鲁斯口琴品牌之一
\n

它独特的压音(bending)技巧就是要故意让音符带上哭腔般的滑音效果,模拟人类最原始的情感表达——哭泣、叹息、呻吟时的声音特征。当你听到那种从正常音高滑落到更低音高的声音时,大脑中处理情感的原始区域会瞬间被激活,因为那就是我们从婴儿时期就熟悉的\"痛苦\"声音模式。

\n

布鲁斯口琴作品旋律性都很突出。先推两首很容易入耳的曲子:法国口琴大师 Jean-Jacques Milteau 的《Fragile》和《Blue 3rd》。

\n

前者让你感受那种脆弱而坚韧的矛盾情感——音符有时轻得像要断掉但韧性十足,通过压音技巧制造出的\"哭腔\"效果来表现用力压抑心碎的情绪;后者则是通过纯熟气息来控制音色和快速节奏变化,制造一种特别流畅欢脱的听感。这两首,一首社恐一首社牛,都能甩开理性直接激发情感参与。

\n

牛逼的布鲁斯口琴曲巨多,不多推了。如果你被击中会自己去发掘的。

\n
\"\"
《Blue 3rd》(Jean-Jacques Milteau)
\n

如果你想感受一下融合了音色、节奏、旋律的现代风格作品,我会推荐 Joe Strummer & The Mescaleros 的《Mondo Bongo》。它收录在 2001 年那张《Global a Go-Go》专辑中,被评价为\"折衷主义的多元文化音乐\",也被选作《史密斯夫妇》电影配乐,OST 里能找到。

\n

这是一首非常有特色的融合作品:以雷鬼节奏为基底,融入了拉丁、非洲等多种来源的根音乐元素。由于大量使用原声乐器,音色质感特别棒,那种自然原生的听感就是前面提到的\"有机感\"。

\n
\"\"
《Global a Go-Go》(Joe Strummer & The Mescaleros)
\n

再推一首跨界的融合作品——马友友和 Bobby McFerrin 合作的《Hush》。Bobby McFerrin 你大概也知道,就是那个能用嘴巴模拟各种乐器、创造出整个乐队效果的人声即兴鬼才,最出名的就是《Don't Worry Be Happy》。

\n

《Hush》这首曲子特别有意思,因为它展现了两种完全不同音乐背景的艺术家是如何找到共同语言的。马友友温暖、有机的大提琴音色和极其自如的节奏把控,配上 Bobby 那种既可以是旋律、又可以是节奏、甚至可以是和声的人声创作,创造出一种一呼一应、一应一和的对话效果,听起来很是调皮,像两个互相欣赏的老朋友在抬杠。

\n
\"\"
《Hush》(马友友和 Bobby McFerrin)
\n

我把这首也视为根源音乐,虽然不符合音乐史理论上的定义,但符合自己认为的特点——没有复杂的编曲或炫技,就是搬个板凳在旁边围观一场质朴本真的即兴表演的感觉。

\n

上面推荐的这些作品,从早期布鲁斯到现代融合,它们都有种根源性的力量,能让你更直观地感受到为什么音乐比语言更能直达内心——它们连接的是我们作为人类这个物种共同拥有的那些本能情感。

\n

调性的魔法

\n

说到情感转换,音乐的调性是不能不提一下的。

\n

我乐理只略知点皮毛。有次向一个专业乐手朋友请教调性的情感特质,他也不多废话,直接手写了一张《生日快乐》的小调转换版。我当时正在学钢琴,照着谱子一弹,立刻就明白了调性的威力。

\n

同样的旋律从大调转小调,整曲画风从”庆祝”秒变”哀悼”,《生日快乐歌》成了《生日不快乐歌》。转换如此直观,无需额外解释。

\n
\"\"
网上搜了一张小调的《生日不快乐歌》谱
\n

然后我请他弹了些更复杂的转调版本,还拿了自己听得贼熟的大曲子求他弹各种变调版(不得不说爵士乐手基本功是真的强,随心所欲转调变调跟玩似的)。总之,那天下午过得无比欢乐。

\n

可以说调性就像音乐的情感基因,比文字中的语调更加精确和持久。

\n

更微妙的还有各种调式——多利亚调式既有小调的忧郁又带着希望光亮,弗里吉亚调式有异域神秘感,混合里第亚调式比大调更开放自由。比如 Miles Davis 的《So What》用的多利亚调式,在忧郁中保持着优雅;Bill Evans 的《Waltz for Debby》在大调中又带着微妙的小调色彩。这几首有兴趣的都可以搜着听听看。

音乐情绪编码可能的三层结构

\n

基于自身体验,我猜想音乐的情绪编码是分层的:

\n

第一层:生理共振

\n

节奏直接影响心率和呼吸频率,音色的泛音结构触发身体共鸣,动态变化模拟情感的起伏波动。这是最直截了当的反应,几乎不需要大脑处理。

\n

第二层:原始情感映射

\n

调性和音程关系激活我们进化过程中形成的情感反应模式。特定音色(比如布鲁斯口琴的哭腔)直接连接人类最原始的情感表达方式,某些节奏模式能唤起深藏在身体里的记忆。这层反应绕过了认知加工,直达情感中枢。

\n

第三层:文化与个人记忆

\n

这才是我们通常以为的音乐感受来源——特定曲目关联的个人经历,文化约定俗成的情感含义,通过学习积累的音乐经验。但个人认为这可能是比较表层的部分。

\n

所以当问\"为什么音乐能瞬间改变情绪\"时,综合以上我的看法是:音乐不像文字那样需要经过复杂的认知加工过程,而是通过多个层面同时作用于我们,其中很多路径都是直达情感中枢的快车道。

\n

当然,以上都是个人的观察和理解,肯定有不准确的地方。

\n

音乐和情感的关系本来就很复杂,涉及神经科学、心理学、文化人类学等多个领域。但正是这种复杂性让音乐变得如此迷人——它可能是你我日常体验里能接触到的最接近魔法的东西了。

\n
\n

补充更新:有知友希望推些容易听的布鲁斯入坑,先介绍下面几个吧。

\n
\"\"
Buddy Guy - 《Aint No Sunshine》
\n

如果你从未听过布鲁斯,不妨先试试 Buddy Guy 版本的《Ain't No Sunshine》,看看这种音乐是否符合你的口味。这首经典的灵魂布鲁斯还曾被收录在 2000 年的电影《诺丁山》(Notting Hill)原声带中,以其深刻描绘的失落与孤独而闻名,讲述了一个人在失去爱人后所经历的痛苦与绝望。

\n

这歌是易入耳的现代风格。他还有一首《What Kind Of Woman Is This?》更流行风,也很棒,一起推荐。

\n

要是你听完后觉得还不错,那就可以继续探索啦。

\n
\"\"
《Midnight Blue》(Tinsley Ellis)
\n

Tinsley Ellis 的风格与 Eric Clapton 非常相似,同样也是个有神技的顶尖吉他手,solo 时辨识度很高。我认为他的音乐也相对符合现代听众的口味,门槛低。

\n

整张《Midnight Blue》专辑都表现出色,其中最推荐的曲目是《Kiss Of Death》。这首歌充满力量与激情,犹如一个中年人在坦诚讲述自己的爱情与失落的故事,就像一杯烈酒,浓烈而易醉。

\n
\"\"
B.B. King -《The Thrill Is Gone》
\n

接下来进入大师环节。这些作品都很古早也更原汁原味,但对现代听众可能需要习惯一下。

\n

首先是 B.B. King,响当当的布鲁斯之王。许多人虽然没听过他的音乐,但不妨碍听到这个名字时感到如雷贯耳(奇葩说:我也有一份功劳!)。

\n

他的代表作之一《The Thrill Is Gone》是一首关于接受挚爱已别的经典之作,洒脱而不乏细腻的情感表达,是糙汉柔情的最佳写照。歌曲中的吉他 solo 部分被视为几乎所有布鲁斯和爵士乐手必扒的学习材料,而他的爱琴\"Lucille\"更是成为了象征布鲁斯精神的谜因。

\n
\"\"
Howlin Wolf - 《Smokestack Lightning》
\n

Howlin' Wolf 是布鲁斯早期的开创者之一,以其粗犷的嗓音和强烈的表演风格而闻名。

\n

《Smokestack Lightning》是他 1956 年的经典曲目。看这个时间就知道,对于我们这些现代听众来说,这是首陈旧、飘浮着古老灰尘的歌。未必十分悦耳,但能充分感受原始的布鲁斯味。

\n
\"\"
Koko Taylor《Wang Dang Doodle》
\n

Koko Taylor 被誉为布鲁斯女王,以其强有力的嗓音和充满灵魂感的演唱风格而闻名。《Wang Dang Doodle》是一首律动丰富、旋律抓耳的古早舞曲,告诉人们布鲁斯并不总是苦大仇深,听着就像在小酒馆里和朋友们欢聚,端着杯子边喝边一起踩着木地板摇摆。

一些扩展阅读:

\n

「闻到清新的皂味,总会想起小时候在老家」香味为什么会影响我们的情绪?你记忆中有「特别的味道」吗?

\n

为什么我们会在虚构的游戏中体验「真实的情感」?这种情感是完全「虚拟」的吗?为什么我无法理解音乐美术等艺术?为什么人在自然里待久了,会觉得内心突然变「轻」了?是环境在治愈情绪,还是自然本身有特殊的能量场?哪部影视或文学作品记录了你生活的城市,并深深影响了你对这座城市的感情?文学作品是如何捕捉城市的「声音」?如果把 emo 当作一种情绪管理策略,它是健康的吗?

音乐和语言的两条路线

\n

音乐和语言在大脑里也许走的是不同的路线。

\n

音乐处理更像是多通道并行——听觉皮层直接处理音高、节奏、音色的同时,边缘系统(杏仁核、海马体)几乎同步激活。整个过程主要由右脑负责,偏向整体性、直觉性的处理。

\n

而语言处理是序列化解码——必须经过语音识别→词汇提取→语法分析→语义理解这样一步步来,主要依赖左脑的布洛卡区和韦尼克区,得按时间顺序逐步构建意义。

\n

简言之,音乐走\"快车道\",语言走\"慢车道\"。

\n

所以除非本身关注点就在歌词上(比如我们听万青的作品,最有嚼头的就是歌词),日常随意播着扫一耳朵的情况下,旋律确实可能比歌词更容易触动情感。

\n

这里面一个可能的关键差异,我觉得是\"语境\"的表达方式不太一样。

\n

音乐的语境相对直接。你听到的那种忧伤、激昂、宁静的情绪,很大程度上通过声音的物理特性就传达给你了。

\n

而歌词的语境则需要更多层处理:先理解字面意思,再结合上下文,最后才能提取出情感内容。这个认知链条一长,那种瞬间的情感冲击力就容易被稀释。

\n

一个听众的进化简史:从音色开始

\n

下面分享自己的体验。

\n

我的音乐偏好变化是从人声到纯器乐。

\n

大学那阵特别迷爵士女声。那时候网络还不发达,天天吃着《音像世界》\"天碟落地\"专栏的安利去淘 CD。那时被什么打动呢?肯定不是歌词——Diana Krall 唱英语我听不懂,小野丽莎唱日语更听不懂。

\n

琢磨了一下,迷恋的应该是各种有质感和辨识性的音色:

\n

Billie Holiday 那种沙哑磁性,Ella Fitzgerald 的丝绸般光滑,Nina Simone 的深沉厚重,每一种音色就像不同的情感滤镜,即使听不懂歌词,那种忧郁、温暖或激情也能瞬间传达过来。

\n
\"\"
Billie Holiday
\n

为独特音色加成的,是歌手的语感——表面上在唱歌,本质上是利用声音讲故事。这涉及到咬字的轻重缓急、停顿的恰到好处、换气时机的巧妙安排,甚至包括某个音节的微妙处理。

\n

而语感,比唱功更传递情绪。

\n

西方歌手里有两位我认为语感极佳的代表:

\n

首推 Stacey Kent,她咬字极其考究,每个词都像经过精心雕琢,那种轻柔但清晰的发音让人仿佛听到丝绸摩擦的质感。作为少见的现场表现胜过录音棚的歌手,仔细听一下她这首音乐会版本的《It Might as Well Be Spring》,你会发现她在面对乌压压的听众时反而能把普通的句子唱出更多微妙层次。

\n

就像我们文化中的根源有纤夫号子、采茶山歌、陕北信天游一样,布鲁斯最初也是劳动人民发明出来宣泄情感的。不同的是,它承载的是水深火热世界更深重的历史创伤,因此显得格外向外释放(情绪化),语言免修饰(粗口多),话题包容性极强(管得宽),上到命运(键政)下到生活(八卦),凡事皆可布鲁斯。

\n

如果用我们这里的主流价值观看,这些聚众花式吐槽妥妥都是负能量(甚至有违法嫌疑),但那种\"call and response\"(呼唤与回应)的形式,原本就来自非洲传统音乐和教堂圣歌,一个人唱出痛苦,其他人用和声安慰。

New World Records 网站上免费分享了一批早期民间录音片段,对最原生态的布鲁斯感兴趣的小伙伴可以听听看(预防针:不悦耳,但保真):

\n

https://www.newworldrecords.org/products/roots-of-the-blues

\n

布鲁斯给人的共鸣感来自其草根互助的基因。呼唤与回应的形式让它从一开始就不是孤独的个人表达,而是集体的情感分担——即使是最深的痛苦,也有人在倾听,有人在回应。

\n

比如 Muddy Waters 的《Mannish Boy》里就能清楚听到这种形式。Muddy 先唱出\"I'm a man\"(俺这么个糙汉子啊),然后吉他和口琴就像其他声音一样回应他,仿佛在说\"嗯呐,你是\"。还有更典型的 Lead Belly 的《Goodnight Irene》,那种一唱众和的感觉就像是一群人围坐篝火,一个人诉说心事,其他人用\"嗯嗯,俺们懂\"\"哎哟喂,可不是嘛\"这样的声音给予共鸣和安慰。

\n
\"\"
《Mannish Boy》(Muddy Waters)
\n

后来和一些乐手朋友聊天——什么路子的都有,古典的、摇滚的、民谣的——那些玩得特别好的,都说自己会经常回去听各种根源音乐,布鲁斯是绕不开的其中之一。

\n

如果要用理论来解释,它用的是人类最古老的声音表达:除了那个呼唤与回应的结构,还有那些能直接触发情感反应的蓝调音符(blue notes)——主要是降三度、降五度、降七度。这些音符在任何文化背景下都能唤起一种说不清的忧伤或渴望,就像某种共性情感的原型。

\n

更有特点的是布鲁斯的不完美。古典音乐理论追求和谐,但布鲁斯故意用那些先不和谐再圆过来的音程连接来体现一开始的自说自话到被理解回应的动态情绪共鸣过程。那种介于大调和小调之间的模糊地带,也正好对应了人类情感的复杂性——既有痛苦也有希望,既有绝望也有坚韧。

\n

从布鲁斯口琴开始情感之旅

\n

好吧,我花了这么多笔墨介绍布鲁斯,就是想安利你试试看。

\n

怎么听呢?推荐从布鲁斯口琴的纯音乐开始。

\n

这种口琴和我们小时候学的复音口琴是两种乐器。复音口琴是 19 世纪从德国发明,经俄国传入中国的,每个音有两个簧片同时发声,追求明亮清脆的音色,很适合演奏《送别》、《茉莉花》这类民歌民谣。

\n

而布鲁斯口琴(通常是十孔单簧片)是老美本土的东西,专为表达复杂情感而生。

\n
\"\"
Hohner 是最知名的专业布鲁斯口琴品牌之一
\n

它独特的压音(bending)技巧就是要故意让音符带上哭腔般的滑音效果,模拟人类最原始的情感表达——哭泣、叹息、呻吟时的声音特征。当你听到那种从正常音高滑落到更低音高的声音时,大脑中处理情感的原始区域会瞬间被激活,因为那就是我们从婴儿时期就熟悉的\"痛苦\"声音模式。

\n

布鲁斯口琴作品旋律性都很突出。先推两首很容易入耳的曲子:法国口琴大师 Jean-Jacques Milteau 的《Fragile》和《Blue 3rd》。

\n

前者让你感受那种脆弱而坚韧的矛盾情感——音符有时轻得像要断掉但韧性十足,通过压音技巧制造出的\"哭腔\"效果来表现用力压抑心碎的情绪;后者则是通过纯熟气息来控制音色和快速节奏变化,制造一种特别流畅欢脱的听感。这两首,一首社恐一首社牛,都能甩开理性直接激发情感参与。

\n

牛逼的布鲁斯口琴曲巨多,不多推了。如果你被击中会自己去发掘的。

\n
\"\"
《Blue 3rd》(Jean-Jacques Milteau)
\n

如果你想感受一下融合了音色、节奏、旋律的现代风格作品,我会推荐 Joe Strummer & The Mescaleros 的《Mondo Bongo》。它收录在 2001 年那张《Global a Go-Go》专辑中,被评价为\"折衷主义的多元文化音乐\",也被选作《史密斯夫妇》电影配乐,OST 里能找到。

\n

这是一首非常有特色的融合作品:以雷鬼节奏为基底,融入了拉丁、非洲等多种来源的根音乐元素。由于大量使用原声乐器,音色质感特别棒,那种自然原生的听感就是前面提到的\"有机感\"。

\n
\"\"
《Global a Go-Go》(Joe Strummer & The Mescaleros)
\n

再推一首跨界的融合作品——马友友和 Bobby McFerrin 合作的《Hush》。Bobby McFerrin 你大概也知道,就是那个能用嘴巴模拟各种乐器、创造出整个乐队效果的人声即兴鬼才,最出名的就是《Don't Worry Be Happy》。

\n

《Hush》这首曲子特别有意思,因为它展现了两种完全不同音乐背景的艺术家是如何找到共同语言的。马友友温暖、有机的大提琴音色和极其自如的节奏把控,配上 Bobby 那种既可以是旋律、又可以是节奏、甚至可以是和声的人声创作,创造出一种一呼一应、一应一和的对话效果,听起来很是调皮,像两个互相欣赏的老朋友在抬杠。

\n
\"\"
《Hush》(马友友和 Bobby McFerrin)
\n

我把这首也视为根源音乐,虽然不符合音乐史理论上的定义,但符合自己认为的特点——没有复杂的编曲或炫技,就是搬个板凳在旁边围观一场质朴本真的即兴表演的感觉。

\n

上面推荐的这些作品,从早期布鲁斯到现代融合,它们都有种根源性的力量,能让你更直观地感受到为什么音乐比语言更能直达内心——它们连接的是我们作为人类这个物种共同拥有的那些本能情感。

\n

调性的魔法

\n

说到情感转换,音乐的调性是不能不提一下的。

\n

我乐理只略知点皮毛。有次向一个专业乐手朋友请教调性的情感特质,他也不多废话,直接手写了一张《生日快乐》的小调转换版。我当时正在学钢琴,照着谱子一弹,立刻就明白了调性的威力。

\n

同样的旋律从大调转小调,整曲画风从”庆祝”秒变”哀悼”,《生日快乐歌》成了《生日不快乐歌》。转换如此直观,无需额外解释。

\n
\"\"
网上搜了一张小调的《生日不快乐歌》谱
\n

然后我请他弹了些更复杂的转调版本,还拿了自己听得贼熟的大曲子求他弹各种变调版(不得不说爵士乐手基本功是真的强,随心所欲转调变调跟玩似的)。总之,那天下午过得无比欢乐。

\n

可以说调性就像音乐的情感基因,比文字中的语调更加精确和持久。

\n

更微妙的还有各种调式——多利亚调式既有小调的忧郁又带着希望光亮,弗里吉亚调式有异域神秘感,混合里第亚调式比大调更开放自由。比如 Miles Davis 的《So What》用的多利亚调式,在忧郁中保持着优雅;Bill Evans 的《Waltz for Debby》在大调中又带着微妙的小调色彩。这几首有兴趣的都可以搜着听听看。

音乐情绪编码可能的三层结构

\n

基于自身体验,我猜想音乐的情绪编码是分层的:

\n

第一层:生理共振

\n

节奏直接影响心率和呼吸频率,音色的泛音结构触发身体共鸣,动态变化模拟情感的起伏波动。这是最直截了当的反应,几乎不需要大脑处理。

\n

第二层:原始情感映射

\n

调性和音程关系激活我们进化过程中形成的情感反应模式。特定音色(比如布鲁斯口琴的哭腔)直接连接人类最原始的情感表达方式,某些节奏模式能唤起深藏在身体里的记忆。这层反应绕过了认知加工,直达情感中枢。

\n

第三层:文化与个人记忆

\n

这才是我们通常以为的音乐感受来源——特定曲目关联的个人经历,文化约定俗成的情感含义,通过学习积累的音乐经验。但个人认为这可能是比较表层的部分。

\n

所以当问\"为什么音乐能瞬间改变情绪\"时,综合以上我的看法是:音乐不像文字那样需要经过复杂的认知加工过程,而是通过多个层面同时作用于我们,其中很多路径都是直达情感中枢的快车道。

\n

当然,以上都是个人的观察和理解,肯定有不准确的地方。

\n

音乐和情感的关系本来就很复杂,涉及神经科学、心理学、文化人类学等多个领域。但正是这种复杂性让音乐变得如此迷人——它可能是你我日常体验里能接触到的最接近魔法的东西了。

\n
\n

补充更新:有知友希望推些容易听的布鲁斯入坑,先介绍下面几个吧。

\n
\"\"
Buddy Guy - 《Aint No Sunshine》
\n

如果你从未听过布鲁斯,不妨先试试 Buddy Guy 版本的《Ain't No Sunshine》,看看这种音乐是否符合你的口味。这首经典的灵魂布鲁斯还曾被收录在 2000 年的电影《诺丁山》(Notting Hill)原声带中,以其深刻描绘的失落与孤独而闻名,讲述了一个人在失去爱人后所经历的痛苦与绝望。

\n

这歌是易入耳的现代风格。他还有一首《What Kind Of Woman Is This?》更流行风,也很棒,一起推荐。

\n

要是你听完后觉得还不错,那就可以继续探索啦。

\n
\"\"
《Midnight Blue》(Tinsley Ellis)
\n

Tinsley Ellis 的风格与 Eric Clapton 非常相似,同样也是个有神技的顶尖吉他手,solo 时辨识度很高。我认为他的音乐也相对符合现代听众的口味,门槛低。

\n

整张《Midnight Blue》专辑都表现出色,其中最推荐的曲目是《Kiss Of Death》。这首歌充满力量与激情,犹如一个中年人在坦诚讲述自己的爱情与失落的故事,就像一杯烈酒,浓烈而易醉。

\n
\"\"
B.B. King -《The Thrill Is Gone》
\n

接下来进入大师环节。这些作品都很古早也更原汁原味,但对现代听众可能需要习惯一下。

\n

首先是 B.B. King,响当当的布鲁斯之王。许多人虽然没听过他的音乐,但不妨碍听到这个名字时感到如雷贯耳(奇葩说:我也有一份功劳!)。

\n

他的代表作之一《The Thrill Is Gone》是一首关于接受挚爱已别的经典之作,洒脱而不乏细腻的情感表达,是糙汉柔情的最佳写照。歌曲中的吉他 solo 部分被视为几乎所有布鲁斯和爵士乐手必扒的学习材料,而他的爱琴\"Lucille\"更是成为了象征布鲁斯精神的谜因。

\n
\"\"
Howlin Wolf - 《Smokestack Lightning》
\n

Howlin' Wolf 是布鲁斯早期的开创者之一,以其粗犷的嗓音和强烈的表演风格而闻名。

\n

《Smokestack Lightning》是他 1956 年的经典曲目。看这个时间就知道,对于我们这些现代听众来说,这是首陈旧、飘浮着古老灰尘的歌。未必十分悦耳,但能充分感受原始的布鲁斯味。

\n
\"\"
Koko Taylor《Wang Dang Doodle》
\n

Koko Taylor 被誉为布鲁斯女王,以其强有力的嗓音和充满灵魂感的演唱风格而闻名。《Wang Dang Doodle》是一首律动丰富、旋律抓耳的古早舞曲,告诉人们布鲁斯并不总是苦大仇深,听着就像在小酒馆里和朋友们欢聚,端着杯子边喝边一起踩着木地板摇摆。

\n
\n

一些扩展阅读:

\n

「闻到清新的皂味,总会想起小时候在老家」香味为什么会影响我们的情绪?你记忆中有「特别的味道」吗?

\n

为什么我们会在虚构的游戏中体验「真实的情感」?这种情感是完全「虚拟」的吗?为什么我无法理解音乐美术等艺术?为什么人在自然里待久了,会觉得内心突然变「轻」了?是环境在治愈情绪,还是自然本身有特殊的能量场?哪部影视或文学作品记录了你生活的城市,并深深影响了你对这座城市的感情?文学作品是如何捕捉城市的「声音」?如果把 emo 当作一种情绪管理策略,它是健康的吗?

\n

以下对“圣旨”展开做些介绍与讨论,以便读者能更好地理解为什么圣旨在市场上只能卖这个价。

\n

圣旨是中国封建社会皇帝制、诏、诰、敕、谕、旨、批等命令的总称。现社会上流传的所谓“圣旨”,多为明清皇帝封赠官员及其先人、妻室的诰命与敕命。诰命 / 敕命是皇帝对臣僚或赐予官阶或封赠爵号并赋予一定特权的凭证文书,生者为封,死者为赠,按照授予对象不同的品级,以不同的材料进行缮写,即所谓“封赠制度”。

\n

由于目前市场上所能见到的诰命 / 敕命都属于明、清两代的制品,因此我也只对这一时期的“封赠制度”加以说明。

\n

通常来说,接受封赠的人员包括以下四类:一、宗室及外戚;二、文武官员;三、边疆少数民族领袖或宗教领袖;四、藩属国的宗室。但现实市场上,我们能遇到的圣旨基本都来自第二类人员,这就注定了其文献价值高度有限。

\n

文武官员接受封赠的条件,明代通常是三年考满合格,个别时期严格点可能还要求有相应的政绩。清代在基本沿袭明代惯例的基础上,还对有功绩的官员额外有封赠。而不同品级的官员接受封赠的次数还不相同,明清两代循例“一品封赠三代,二、三品封赠二代,四品至七品封赠一代,八、九品只封赠本人”。这也意味着伴随仕途的迁升,官员会不断被“封赠”,潜台词也就是存世诰命 / 敕命的数量不会太少,尤其是清代中晚期以后的此类制品。而数量多也意味着其稀缺性有限。

\n

我之前发了一条想法,里面便提到仅这个人的诰命,文保所就保存了一套共四件。

\n

崇祯诰命

\n

此外,明清两代的诰命形制虽然不同,但都遵循品级越高,材质越好这一规律。而市场上流通的圣旨基本都属于中低级官员,这也就意味着其材料本身就比较普通。加之存世绝大部分的圣旨都属于清代中晚期,国力的衰退更导致其制作上的粗疏,精美程度也随之大打折扣。

\n

对比下面两件清代不同时期的诰命,很容易就能区分出材质精美程度的不同。

最后提一点,诰命 / 敕命是属于个人色彩极其鲜明的文物,与之类似的还有被称为祖容像的画作。这种极具私密属性的文物,在中国人传统观念里,多少都带有忌讳的色彩,甚至会不可避免地与死亡相联系,故而其并不为绝大多数收藏者所喜好(圣旨相对祖容画还好一些),这自然也影响到了它们在市场的流通性与成交价格。

\n

不为什么,“分公母”是一小撮生物的祖征。

\n

任何可遗传性状,只要不导致携带者的可育后代数量明显减少,就可以作为中性性状持续存在。

\n

对于脊椎动物的典型形体构型,靠再生能力较低且有循环系统的身体进行出芽、分裂、断裂之类无性生殖并不方便,但是用生殖细胞搞孤雌生殖就方便起来了,当前地球上个体数量最多的爬行动物物种可能是搞了四千多万年孤雌生殖的钩盲蛇,该物种无雄性个体。

\n

自地球生物诞生以来,以物种数量、个体数量计,无性生殖远比有性生殖更普遍。当前存在的有性生殖物种很可能在距今十几亿年前有个共同祖先[1][2],该祖先的一些后代还放弃了有性生殖。

\n
    \n
  • 对于细胞生物,当前绝大多数物种、绝大多数个体是无性生殖的原核生物——细菌、古菌。
  • \n
  • 非细胞生物(病毒)不进行有性生殖。现存非细胞生物的物种数量可能多于现存细胞生物。
  • \n
  • 亚病毒因子尚未被普遍接受为非细胞生物。亚病毒因子不进行有性生殖。
  • \n
\n

以生物量计,维管植物会让有性生殖在地球生物中的占比大幅上升。不过,许多维管植物在野外亦能进行无性生殖。

\n
    \n
  • 在没有人为干预的情况下,提供最多生物量的维管植物物种们大多是能够进行有性生殖而不怎么擅长进行无性生殖的。
  • \n
  • 在人为干预下,所有维管植物都能进行无性生殖。
  • \n
\n

动物的同卵双胞胎也可以视为一种无性生殖、克隆。人现有的身体可以通过同卵双胞胎进行有限的无性生殖。在人为干预下,许多动物可以进行克隆。

\n

此外,对于有性生殖的物种,同配生殖的物种、细胞融合再分裂的物种是有性而无性别的,许多物种的正常个体是全都雌雄同体的,许多物种有超过两个交配型。许多线虫、许多扁形动物、许多植物是自交的。“分公母”是非主流现象。

\n

对于“为什么一部分物种有两个性别”,可以看看我回答过的:性别是如何演化出来的?

\n
    \n
  • 原始多细胞生物的细胞同时具有体细胞与生殖细胞的功能,种群中可以随机出现“一部分细胞变得比其他细胞更擅长维护修理基因组,从而比其他细胞更适合用于自我复制”的个体,这些个体有概率延续下来产生同配生殖种群、物种;配子体积的随机变动可以互相筛选出体积差异很大的配子(小型配子在制造和移动时更节约资源、可以大量释放,大型配子比更小的配子更擅长与小型配子结合产生后代),这些个体有概率延续下来产生异配生殖种群、物种。
  • \n
  • 在这种模式下,有性生殖无需有任何优势,在过去十几亿年里还没糟糕到携带者全部灭亡就行了。
  • \n
  • 顺便说,“一部分细胞变得更擅长”的实现方式包括“其他细胞变得更不擅长”。在生物体内,“做减法”比“做加法”要容易发生:只要随机搞错了一个碱基,就有可能废掉一系列能力或改变大量的调节因素。
  • \n
\n

一些人尝试给有性生殖找“好处”,这经常导致纯粹的谬误。另一方面,有性生殖也没有重要的缺点,人们日常找的“缺点”要么不存在要么无所谓。可以看看我回答过的:有性生殖有哪些缺陷?

\n

在这问题下,读者可以看到很多回答在幻想多样性。

\n

基因组中的大部分遗传多样性是中性的,既不会提高也不会降低个体生存或产生后代的能力。

\n

与生物的环境耐性(包括疾病抗性)相关的基因,影响个体生存或产生后代的能力的遗传多样性,存在于基因组内非常特定的区域,与全基因组的遗传多样性完全无关[3]。快速传代、大量繁殖的无性生殖物种或孤雌生殖物种完全可以拥有压倒有性生殖物种的环境耐性。

\n

不限于无性生殖或孤雌生殖,许多入侵物种抵达新地区时只有数个个体,基因多样性暴跌,但迅速发展为庞大的新种群,并在特定的基因上显示出迅速适应。2021 年,科学家在入侵物种“绿蟹”身上再次确认了这件事[4]。人自己也是很好的证据。

什么?还在考虑寿命增加或缩短?

\n

体温都得超过 300℃,直接熟透了好吧。

\n

以下是分析和计算过程:

\n

一个人在静息状态下的平均功率为 100W 左右,细胞分裂速度突然加快 100 倍,意味着静息功率至少突然激增到了 10000W。

\n

要知道博尔特的瞬时最大功率也才 2000 多 W。

\n

你这一身的功率,相当于 5 个博尔特在冲刺。

\n

如果高的功率,人体温度会有多少呢?

\n

我们不放一算。

\n

根据斯特藩 - 玻尔兹曼定律:

\n

为:

\n

582.32K,也即 309.17℃。

\n

这么高的温度,意味着即便人体充分发挥散热能力,降低一点点温度也是杯水车薪。

\n

所以,人很快就熟透了。

\n

这个问题下的众多答主,都忽略了一个非常严重的问题。

\n

细胞分裂速度突然加快 100 倍,意味着新陈代谢至少会加快 100 倍。

\n
    \n
  • 考虑到微环境的骤然改变,生化效率的降低,实际支撑 100 倍分裂的新陈代谢加速远远不止 100 倍。
  • \n
\n

有人不理解为什么,分裂速度加快 100 倍,新陈代谢为啥就会加快 100 倍。大家都会这么想,的确干细胞的功能谁要是分裂增值分化,但是分化后的细胞不是主要是其他功能吗?它们也不再分化,整体新陈代谢不应该会增加 100 倍啊?

\n

我这里再详细解释一下,为什么新陈代谢也会加快 100 倍。

\n

第一点,细胞分裂速度和生化效率直接相关。只有提升了干细胞的生化效率,分裂速度才能加快。干细胞的新陈代谢主要都发生在分裂上面,因此新陈代谢会提升 100 倍。

\n

第二点,细胞分裂速度加快 100 倍,人体还需要正常维持,说明细胞总量还没变话。也就是说新旧细胞也完成了 100 倍加速更替,意味着老细胞生命周期和凋亡速度也需要加快 100 倍,它们的新陈代谢速度也需要加快 100 倍。

\n

第三点,细胞分裂速度提升 100 倍,其实突破的是生化反应效率和速度(物理法则)。人体是一个体液共享的生化反应池,生化环境是一个整体,要么一增俱增,要么一减俱减少,不可能存在初始条件完全不变,只增效特定细胞生化反应的情况。

\n

第四点,除了共享生化反应池外,人体也是众多系统联合存在的。任何一种功能都是和其它功能相关联的,例如生长发育和消化、循环、呼吸、运动系统等等的正关联。生长发育相关的细胞增速 100 倍,其它系统也需要被迫增速 100 倍。

\n

很多人并没有意识到,100 倍增加有多夸张。人体细胞每天的更新率为 1%~2%,增加 100 倍,意味着更新率变成了 100%~200%,一天就会增加 1~2 个人体的更新量。即便不考虑其它能量增加,消化系统所需要的摄入量,是不是都朝着 100 倍提升了?消化系统提升了 100 倍,其它系统是不是也被迫提升 100 倍?

\n

总之,虽然题设的确只有分裂加快 100 倍,但要支撑这个复杂有机体存在,还有生命周期和凋亡速度的 100 倍,其实 100 倍新陈代谢其实都打不住。

\n

从演化的角度来说,细胞分裂速度也不可能凭空增加 100 倍。

\n

一个细胞,其实就是一个超级“工程”,仅仅一秒钟,就会发生一千万次的生化反应。

\n
\"\"
\n

生化反应的效率和速率,在不同的温度、浓度、压力、电流、催化剂条件下有所不同。但受限于不同位置不同元素最外层原子轨道(物理法则),最高上限也被死死卡死。

\n

生物演化到一颗细胞这样的复杂程度,用了多少年的时间?

\n

至少 20 亿年。

\n

42.8 亿年前,或许已有了最早的生命。但一直到 18 亿年前,才可能有了最早的真核生物。

\n

如此漫长的 20 多亿年,经过不断的淘汰迭代,只有生化效率和速率越能适应环境,才越能生存下来。

\n

当环境恶劣时(营养缺少、废物积累、环境有害),它们的生长发育和分裂繁殖都会减慢。当环境优渥时(营养丰富、废物清除、环境适宜),它们的生长发育和分裂繁殖都会加快。

\n

这一条,不仅仅是原核生物、原生生物,甚至是众多多细胞生物的生存法则。

\n

生物们不是不想凭空加快分裂繁殖,而是根本不能。

\n

唯一可能做到加快 100 倍的,只有这样的情况:

\n
    \n
  • 比原生生物(包括)更加简单的生物,通过提供无比优渥的环境,来使得原本生存在极其恶劣环境中的个体,分裂速度加快 100 倍。
  • \n
\n

而原本生存在优渥环境的简单生物,便不可能做到分裂速度加快 100 倍,因为被生化效率和速率限制得死死的。

\n

至于多细胞生物,尤其是刺胞动物之后,演化出组织、器官,甚至是系统的生物,更是根本不可能做到。

\n

生物为什么演化出器官和系统,因为对于多细胞生物来说,相同功能的细胞集中才能干“大事”,才能出效率。

\n

心脏源源不断的提供动力,负责血液循环。

\n

肺源源不断的提供新鲜氧气,并排出二氧化碳。

\n

肠胃源源不断的摄入营养。

\n

肝脏则肩负着消化、营养转化、储能、代谢、解毒等多种多样的功能。

\n

肾脏则过滤血液中的杂质、维持体液和电解质的平衡。

\n

……

\n

复杂生物的器官,同样在一次次自然选择中,越来越匹配生存效率。不说提供 100 倍,哪怕是提高 2 倍,都是在超频了。健康人的心率在 70 左右,再年轻,也就超频到 3 倍左右。

\n

100 倍,对于这些复杂器官来说,简直是过于夸张。

\n

新陈代谢提升 100 倍,意味着血液循环的效率需要提升 100 倍以上,心脏自然只能直接爆缸了。

\n

而肺泡交换氧气的效率也需要提升 100 倍,肺内部空间就那么大,再怎么优化,也不可能提升 100 倍。直接炸了,无根本做不到。

\n
\"\"
\n

人的体液、电解质、酸碱都维持着动态平衡,新陈代谢速度提升 100 倍,也意味着消化系统需要提供 100 倍的物质供应,把肠胃吃得堵死了也根本做不到。

\n

至于肝脏和肾脏,两个都是要不毒死,要不忙死。

\n

你想大脑不负责这些基础功能,除了海马体神经元也基本上不细胞分裂,能逃过一劫吧?

\n

你想多了,根本不可能。

\n

的确,大脑主要的神经元是终生制的,可惜神经元其实仅仅只是大脑细胞的少部分,多达 90%的细胞其实是是神经胶质细胞。神经胶质细胞终身具有分裂能力,原本神经胶质细胞仅仅只是自然更替,突然分裂加快 100 倍,看看这这脑瓜子还能撑到几时。

\n

我们退一万步来说,即便这些细胞足够快的凋亡,大脑也不可能平安无事。

\n

覆巢之下安有完卵。

\n

人体高功率产生的热量,就完全受不了。

\n

前文我们计算了提升 100 倍的新陈代谢率,人体温度达到夸张的 300℃以上。

\n

人类历史上发烧最高纪录是 46.5℃, 1980 年 7 月 10 日一 52 岁亚特兰大黑人所创造。

\n

我们不放把这个温度作为人体烧死的上限。

\n

容易计算出:

\n

人体静息功率只需要长期维持在 219W,就足以把人烤死。

\n

当然,这个数据是人体不散热的情况下。

\n

考虑到可以通过外界冷风、发汗等方式散热,人体的功率上限其实是可以非常高的,可以接近 1000W。

\n

如果用接近 0℃的高速水流进行全身冲刷,或许 2000W 都能抗住。不过考虑到,人体类似于一个圆柱体,从内到外是存在温度梯度的,内部温度过高也会死掉,大概率也抗不了大几千 W(虽然体表散热足够)。

\n
\"\"
\n

所以。还是建议不超过 200W,毕竟稍有不慎,在睡觉的时候没有创造散热条件,就直接烧死了。

\n

而 200W 对应的新陈代谢增加倍数,也才 2 倍而已。

\n

即便我们考虑到个体差异,留一点点的余量,我们基本上也可以下一个这样的结论:

\n

对于恒温动物来说,能够支持的细胞分裂增速,通常无法超过 3 倍。当变温动物从较冷温度到较高温度环境时,能够支持的细胞分裂增速远远超过恒温动物,个人推测也应该无法超过 10 倍,同样距离 100 倍甚远。

\n

加快 100 倍,还想着寿命是更长还是更短,很明显想多了呢。

\"头图\"/
\n

因为休息已经不再是休息了,它变成了一场表演,一种投资,一个不能\"亏\"的“生意”。

\n

对,现代人最怕的就是:不知不觉\"亏大了\"。

\n

这种体验都不陌生吧:

\n

周五下班,累成狗,脑子里只有一个坚定的念头:明天非睡个天昏地暗不可,谁都别想打断我!但当你真的窝在沙发上,刷着手机,看到朋友们的精彩\"周末预告\":有人去踩点快闪,有人露营徒步,有人去看新展...

\n

一种焦虑感蹭就冒上来了:\"所有人都在过'有意义'的周末,就我在浪费时间。\"

\n
\"\"
\n

休息变成了避免\"损失感\"的竞赛

\n

这种休息焦虑,指向的是一种特别难受的损失感,但这不是现代人的专利。

\n

上世纪 50 年代,一位看起来不太合群、名叫费斯廷格的心理学家注意到一个现象:人们总是忍不住拿自己和别人比较。他跑去学校食堂蹲点,发现学生们排队打饭时会不自觉地瞄一眼别人盘子里有什么。后来他把这种现象总结为\"社会比较理论\"。

\n

但费斯廷格肯定想不到,他观察到的这种比较心理会在社交媒体时代被放大到如此可怕的地步。

\n

当所有人都在晒户外活动、旅行照片、精致生活,你会本能地产生一种\"我错过了什么\"的焦虑。每刷到一张别人的精彩假期照片,大脑就会自动计算:这本可以是我的体验,但我错过了。

\n

经济学家们管这叫\"机会成本\",但我更愿意叫它\"朋友圈剥夺感\"。

\n

\"要命的是,失去的痛苦远比得到的快乐强烈得多。\"这不是我说的,是那些研究人类非理性行为的行为经济学家发现的。他们给这种现象起了个专业名称——\"损失规避\",但放在日常生活中,就是\"怕亏\"。

\n

想想看,得到 100 块的快乐,远不如失去 100 块的痛苦强烈。这就解释了为什么\"错过一个假期体验\"的焦虑,远大于\"在家舒适休息\"的满足感。

\n

所以我们休息不再是为了恢复精力,而是为了避免落后、避免损失。

\n

那么懂这些道理,就能躲过去了吗?

\n

呵呵,天真。

\n

我前段时间熬夜写稿调模型,感冒,嗓子疼得要命,原本打算第二天就纯休息,最多补完《人生切割术》第二季一直拉下的最后两集。结果当天就看到朋友发了某个限时艺术展的照片,标注\"最后一天\"。

\n

虽然我确实对那个展很心动,但也意识到自己被“损失感”牵到鼻子了。猜猜我做了什么?明知道这是损失感在作怪,还是拖着病体去\"打卡\"了。整个过程喉咙像被火烧,展览只看了个大概,回家后病情加重(活该)。但至少,朋友在脸书上发的那篇艾特了我的 po 文,证明了我这个周末\"没有浪费\"。

\n

我们的休息被扭曲成了一场避免\"损失感\"的竞赛。这种所谓的\"没浪费\",恰恰是对休息最大的浪费。

\n

真·休息的核心要素:自主性和无目的性

\n

仔细想象,真正的问题不在于\"宅家还是出门\",而在于决策的主体是谁。

\n

是你的身体和真实需求在做决定,还是社交媒体上的隐形压力?是你真的想去,还是害怕错过?

\n

人类有三种基本心理需求:自主感、胜任感和归属感。这些\"自我决定理论\"的三角核心,其实说的是个很简单的道理:当我们的行为由内在动机驱动时,即使累也会觉得值得;而当行为由外部压力驱动时,即使表面看来很\"享受\"也会感到空虚。

\n

这就解释了一个现象:为什么有些人假期玩得\"精彩绝伦\",回来却像被榨干了一样?因为他们的休息没有自主权。

\n

哈佛的丹尼尔·吉尔伯特在他一本书中描述过做过的一个实验。他让人们预测各种经历会带给自己多少快乐,然后再追踪他们的实际感受。结果发现人们普遍高估了\"特别体验\"带来的快乐,低估了日常平静时光的价值。

\n

我们被训练去追求那些\"值得发朋友圈\"的体验,却忽略了真正让我们感到满足的可能是那些不起眼的安静时刻。

\n

划重点!真正的休息有两个核心要素:自主性和无目的性。它不是为了什么,也不是给谁看的。

\n

想想小时候在床上看漫画的感觉。没人问\"看漫画有什么价值\",没人需要把看漫画的照片发到哪里去证明什么,就那么躺着,一会翻个身,看到累了睡觉。那种纯粹的满足感,就来源于完全的自主。

\n

\"无所事事\"比你想象的重要

\n

休息本身应该无目的性,而假期就是用来享受“无所事事”的。

\n

我甚至认为,\"无所事事\"可能是人类作为高等生物最重要的能力之一。但在这个时代,这种观念必然被视为洪水猛兽。

\n

大脑里有个系统叫\"默认模式网络\"(DMN)。这名字起得不怎么样,听起来像某种软件设置。但这个系统却是我们最神奇的部分之一。

\n

神经科学家马库斯·莱希尔在 2001 年首次描述了这个网络。他原本在研究人类大脑的活跃区域,却意外发现一个奇怪现象:当受试者什么都不做、就是单纯\"放空\"时,大脑中某些区域不但没有停工,反而比平时更活跃。这些区域组成了 DMN,它负责自我参照思考、记忆整合和创造性联想——这些恰恰是创意和洞见产生的关键过程。

\n

这一发现深化我们对\"发呆\"的理解:看似无所事事的时刻,大脑实际上在进行着深层次的重要工作。

\n

2019 年另一项相关研究进一步证实,强迫人们不断保持\"高效利用时间\"的状态会显著损害创造力和问题解决能力。这解释了为什么我们最好的想法常常出现在淋浴时、散步时或者刚醒来的时候,而不是在紧张工作时。

\n

一些被公认的天才,例如爱因斯坦幻想自己骑在光束上旅行时想到了相对论,乔布斯在印度冥想时想到了简约设计理念。他们的共同点是——都允许自己\"浪费时间\"。

\n

反而并非天赋异禀的我们,连上厕所都要带着手机,生怕浪费那几分钟就错过了全世界。我们把每分每秒都塞满内容,却不明白为什么创意枯竭、思维僵化。

\n

答案也很简单:我们剥夺了大脑\"无所事事\"的权利,也就关闭了通往创造力的大门,同时,顺便关上了好好休息的那扇窗。

\n

波兰社会学家鲍曼说得透彻——当代社会把一切都变成了表演和消费,连休闲都不能幸免。我们不是在活着,而是在向别人证明我们活得\"正确\"。

\n

多荒谬啊,为了证明自己\"会休息\",反而让自己更疲惫;为了显示没有\"浪费假期\",却浪费了真正的休息机会。

\n

而这场表演到底给我们换来了什么?几个点赞?几句羡慕?还是真的让自己更快乐、更有活力了?

\n

再理性点算一下帐:到底赚了还是亏了?

\n

最后想对你说

\n

真正的休息像呼吸一样自然,不需要事先计划好每一步,不需要在社交媒体上好看,不需要讲出来显得很酷。

\n

休息的价值不在于它能被展示成什么样子,而在于你有没有确定谁是它的主人。想躺三天,就躺三天;中途无聊想出门疯一下,那就改变计划。这些都不需要向谁解释,因为这是你的时间,你的选择。

\n

最根本的是:休息是你和身体的私密对话。

\n

那些插入这段对话的外部声音——社交媒体、同事的假期炫耀、亲友的期待——都是不速之客。礼貌地请它们出去,收回对话的主导权。

\n

而休息之外,敢于在众目睽睽下“无所事事”,或许更是这个时代最稀缺的反叛之一。

\n

进入五一长假了,说这么多,就是希望你不再为\"宅在家\"感到愧疚,即使已经稍显“爹味”了。

\n

这个假期,祝大家(也包括我自己)能真正休息,而不只是假装休息。祝我们都能从允许自己\"浪费时间\"开始,找到属于自己的休息方式,无论它看起来多么不\"精彩\"。

\n

这个话题的内涵有很多延伸(例如人生阶段性的时间感知、社交媒体的表演性焦虑等),附上几篇相关的联动阅读给有兴趣的朋友。也欢迎告诉我你的感受!

\n

在社交媒体时代,我们是否已经习惯了“被观察”,从而在潜意识里塑造了一个“表演版自我”?当「享受孤独」仿佛成为全民必修课,我们在逃避的本质是什么?还是在寻找更高级的共鸣?在明白什么道理后,你不再焦虑了?如何才能让一个中年人真正的快乐?长大后觉得「时间过得更快」,这种现象是自古有之?还是现代人特有的主观感受?

在「同时处理多个任务」对大脑来说难在哪里?中,我解释了关于注意力的基本概念和原理,这一系列的内容可以更简化的解释:

\n

大脑区域的任务特异化分工

\n

这一点可能大家多少有所耳闻。比如大脑的有负责听觉的区域,负责视觉的区域[1] 以及 负责嗅觉的区域。通常意义上,这些功能区域内部又构成一定的拓扑结构,越底层的结果功能越单一,处理的信号内容越特异化,而越高层的结构,处理的信号越多样化且复杂,而功能越多样化。

\n

典型地,基础视觉区域 V1 的功能较为简单,它处理完信号之后按照视觉皮层拓扑结构再传递给更高层级的脑区,以处理更复杂的信号。

\n
\"\"
\n

随着视觉信号数据传到更高层级的区域(V4,MT 等),信号本身表现的越来越复杂[2],同时这些区域自身还能处理非视觉信号。对应地,V1 区域则相对较少处理其他类型的信号。

\n

大脑的任务特异化和状态固化

\n

大脑的每个区域都会优先处理各自对应类型的信号,同时都在争夺处理信号的资源(血流、血氧、能量供给等),如果不加控制,大脑内部必然乱作一团。

\n

大脑内部调控资源机制为 执行控制信号(Executive control signals)[3]. 每当大脑决定做一项任务时,执行控制信号会发出,对应的大脑区域被优先分配资源,而其他区域则被压制,这一状态在任务的整个阶段都被执行控制信号维持住。这类似于对计算机编程,配置好之后的人脑为任务做好了准备,并在一定时间内,处理任务的过程中能不断的优化配置,使得对该任务的处理效率不断提高。

\n

在维持过程中,我们可以通过各种设备观察到大脑内部的不同区域构成一个协同处理任务的子网络,并处于活跃状态[4], 这本质上是注意力控制系统在起作用。

\n

因为任务相关区域的活跃和其他区域的被压制,在可感知的意识范围之内,任务相关的信息占比会大幅度的提高,而其他信息的占比则接近消失。

\n

这在感知上表现为对信息的筛选,实际上是大脑决定做某件事之后自然发生的结果,并非我们自主决定和执行了对信息的“筛选”。相反,如果我们有意识的进行对信息的筛选,会因为这套调控机制而放大想要筛选的信号在认知中的比例而起到相反的效果。

\n

异常状态

\n

在执行控制信号不能有效作用的时候,我们的认知(包括注意力)就会异常。

\n

比如睡眠态,这套系统完全不起作用,大脑内各个区域的信号几乎平等的争夺已经被降低的资源并发出自己的信号。由于注意力调控完全不起作用,这些各种各样的信号会平等的进入到残存的意识从而形成梦境。所以梦境会表现为内容特别丰富,但这些内容又难以形成连续且合乎逻辑的故事,总是被新的内容信号打断而发展到完全意外的路线上。

\n

对于神经系统异常的人,比如抑郁症、多动症,或者过于疲劳等,要么执行控制信号本身就有问题,要么执行控制信号想要控制的对象区域有问题,从而让注意力表现异常,无法有效筛选信息[5]。

我造了什么孽,要把我扔到太平洋中央
\n

更新:文末增加人类野外游泳记录,同时探讨生理表现和限制,供大家作为对比。

\n

很多知友十分关心不同动物的游泳表现,我选取了其中一些有代表性的进行了全面比较。放在正文会变得十分冗长,作为延伸阅读附在文末。

\n

把一只成年湾鳄投放到太平洋中央,就相当于把一个人丢到撒哈拉沙漠的中心地带——要吃的没吃的,环境条件极不适合生存,而且最要命的是四周都是一望无际的相同景象,完全无法判断方向。

\n

让我们用数据来分析这个问题。太平洋中央距离最近的陆地通常超过 2000 公里。即使是体力充沛的成年湾鳄,其游泳速度一般为每小时 2-3 公里,在理想状态下不眠不休地游泳,也需要近一个月才能到达陆地。但这种计算忽略了一个关键问题:能量消耗。

\n

根据爬行动物生理学研究,咸水湾鳄在静止漂浮状态下的基础代谢极低,仅为体表面积所决定的热耗率的 1/5 到 1/10。实验数据显示,一只约 200 kg 的鳄鱼静止时代谢功率仅约为 50–70 W(即每小时消耗 43–60 kcal),这是典型的节能状态。而当其进入持续游泳模式时,功率可上升至 400 W 左右,相当于每小时约 344 kcal。

\n

若按体重代谢的 0.75 次幂规律推算,一只体重约 500 kg 的雄性湾鳄在持续游泳时的功率约为 800–850 W,即每日能量消耗约为 16,000–20,000 kcal。这一水平虽远低于同体重的哺乳动物,但相比其静息状态,能耗已增长十余倍。例如,成年男性人类在自由泳中平均输出功率为 200–400 W(相当于 170–340 kcal/h),而马或狮子在剧烈奔跑时可达到 1000–1500 W,但难以长时间维持。

\n

此外,湾鳄的脂肪储备远不如哺乳动物,通常仅占体重的 5%–8%,即 25–40 kg 脂肪,总能量相当于 225,000–360,000 kcal(按 9 kcal/g 计算)。在上述高强度游动下,这些脂肪最多只能支持 13–22 天,前提是完全禁食、无任何进食补给、恒定环境下持续运动。这一“燃料极限”远比人类、狮子或海洋哺乳类(如海豹、海狮)短,后者拥有更厚的脂肪层与灵活的摄食策略。

\n

因此,虽然湾鳄在能效控制方面极其出色,但在高强度长途迁移中若无法及时捕食,其生理耐受极限远比外表“耐饿”的印象要脆弱得多。

\n

而且实际情况比这个还要严峻得多。

\n

太平洋中央的表层水温通常在 20-25°C,而湾鳄的最适温度是 28-33°C。作为变温动物,低温会导致其代谢率下降约 30-40%,游泳效率也相应降低。更要命的是,湾鳄必须不断游动才能保持在水面呼吸,这种被动的持续运动会加速体力消耗。

\n

此外,湾鳄若长时间在海水中活动,尽管具备舌腺排盐功能,但其效率有限,若无法定期返回淡水环境排盐,将面临脱水与电解质失衡的风险,严重时可导致肾功能障碍甚至死亡。

\n
\"\"
\n

在体型对比上,湾鳄在海洋中毫无优势可言。成年雄性湾鳄平均体长 4-5 米,体重 300-500 公斤,最大个体可达 7 米、1000 公斤。但在深海中,大白鲨体长可达 6 米,体重超过 2 吨;虎鲨体长 5-6 米,体重可达 900 公斤;而虎鲸更是体长 8-10 米,体重 6-9 吨的庞然大物。更关键的是,这些海洋掠食者都是完全适应深海环境的,拥有流线型身体和强大的游泳能力。

\n
\"\"
虎鲨有强大的咬合力和强壮锋利的牙齿
\n
\"\"
海龟整个后面都被咬烂了,不存在破不了湾鳄的防
\n

湾鳄在浅水区的优势——强大的咬合力(可达 3700 磅 / 平方英寸)、爆发式的死亡翻滚、坚固的骨板保护,在深海环境中都大打折扣。它无法像在浅水区那样利用水底支撑进行爆发攻击,也无法快速潜入水底躲避。相反,体力逐渐耗尽的湾鳄游泳速度会从每小时 3 公里降到 1 公里以下,而大白鲨的巡航速度是每小时 40 公里,爆发速度可达每小时 56 公里。

\n
\"\"
鲨鱼确实会吃鳄鱼
\n
\"\"
相反的例子。近海尤其是体型优势下,还是湾鳄占优势
\n

食物获取更是几乎不可能完成的任务。太平洋中央属于海洋荒漠区,初级生产力极低,每平方米每天的浮游植物生产量仅为 0.1-0.2 克碳。这意味着整个食物链的生物量都极其稀少。湾鳄在近海一天可能捕食 10-20 公斤的鱼类,但在深海可能几天都遇不到一条合适的猎物。

\n
\"\"
咬合力再强没有鱼也是白给
\n

历史上确实有湾鳄长距离迁徙的记录。最著名的案例是 2010 年,一只装有卫星追踪器的雄性湾鳄在 25 天内游了 590 公里,从澳大利亚北部海岸游到了另一个河口。但请注意,这是沿着海岸线游泳,期间可以在多个岛屿和浅滩休息进食。这与在太平洋中央的情况完全不同——那里最近的陆地在 2000 公里之外,中间没有任何休息点。

\n

综合计算,一只被投放到太平洋中央的成年湾鳄,在尽量节省体力利用洋流漂浮的前提下,其脂肪储备最多只能支撑 20-25 天。而在这期间,它游泳的距离不会超过 1500 公里,还不到最近陆地距离的四分之三。更可能的情况是,在体力耗尽之前,它就已经成为虎鲨或大白鲨的猎物了。

\n

当然有一种可能,湾鳄运气爆棚,遇到了死亡漂浮的鲸鱼尸体饱餐一顿。补充了够消耗几个月的巨量蛋白质。

然后正好遇到一阵海风,美美睡一觉漂到了附近岛屿。

延伸阅读:

\n

从湾鳄到金枪鱼,动物游泳能力与能量效率的极限对比。

\n

不同动物在水中的游泳能力与能量效率体现了演化适应性的巨大差异。从人类、爬行动物、海龟,到鲸豚类和远洋鱼类,它们在单位体重单位距离上所需的能量消耗差距可达数十倍。

\n
\"\"
自由泳是人类最节能高效的泳姿,单位能耗最低,适合长距离推进。
\n

以人类为例,在自由泳状态下的巡航速度约为 1.0 米每秒(即 3.6 公里每小时),单位质量单位距离的能量消耗约为 3000 焦耳每千克每公里,总能耗为 21 万焦耳,折合 50 千卡,平均功率约 210 瓦,属于效率偏低的“非水生动物”水平。

\n
\"\"
\n

相比之下,体重 500 千克的湾鳄虽然能够在水中伏击猎物,但其正常巡航速度约为 0.7 米每秒(2.5 公里每小时),持续游泳时的功率为 800–850 W,折合每公里能量消耗约为 144–150 万焦耳(约 344–358 千卡)。虽然湾鳄作为变温动物代谢率相对较低,但其身体构造并非为长时间持续游泳而优化,因此在大范围水域中的能效表现远逊于真正的海洋动物。

\n
\"\"
\n

值得注意的是,鳄鱼在水中的捕猎爆发速度与其长距离巡航能力完全不同。湾鳄在伏击猎物时可瞬间加速至每秒 4 至 5 米(14 至 18 公里每小时),但这类冲刺依赖瞬时的无氧代谢,仅能维持数秒,远不能支持长时间推进。其心肺容量、血氧携带能力和能量储备均不具备维持高速持续游泳的条件。此外,鳄鱼由于仍需兼顾陆地活动,其体形结构未经过水中长期演化的优化。相比之下,鲸类、鲨鱼等海洋动物拥有流线型外形、减阻皮肤和专业推进系统,使得它们在巡航效率和能量利用方面大幅领先。鳄鱼厚重的躯干、粗糙的鳞甲和以陆行为基础的四肢形态,在深远水域中反而构成了明显的阻力与负担。

\n
\"\"
绿海龟虽名为“绿”,但背甲常呈红棕色,这是因其角质鳞片中含有多种色素,加上藻类附着和地理变异所致。其“绿色”实指体内脂肪因摄食海草富含叶绿素而呈绿色,而非外表颜色。
\n

绿海龟虽然也是空气呼吸的爬行动物,但由于其流线型身体和鳍状肢更适合长时间水中推进,表现明显优于鳄鱼。其单位能耗约为 2000 焦耳每千克每公里,体重 100 千克的个体每公里总耗能约 20 万焦耳,折合 48 千卡,平均功率约为 140 瓦。

\n
\"\"
\n

研究发现,部分绿海龟个体会在繁殖季节从日本南部沿岸游至南太平洋的马绍尔群岛,单程距离超过 7000 公里,历时数月才能抵达目的地。绿海龟具有惊人的\"出生地回归\"(natal homing)能力——它们在性成熟后(通常需要 20-30 年)会返回自己出生的海滩产卵。幼龟孵化后会立即爬向大海,然后进入被称为\"失踪岁月\"的阶段,在开阔洋面随洋流漂流数年,期间依靠马尾藻等漂浮物提供的庇护和食物生存。在这个阶段,大量幼龟会被海鸟、大型鱼类等捕食者吃掉,存活率极低。只有少数幸存者能够逐渐成长,最终发展出强大的游泳能力,完成跨洋迁徙。这种精确而持久的定向迁徙能力依赖其对地磁场的感知、太阳定位和洋流导航的综合机制。尽管绿海龟的游速不高,约为每小时 2 至 3 公里,但其在食物匮乏、无补给的广阔洋面中仍能维持能量平衡,展现了极高的水中推进效率和适应性。

\n
\"\"
样子太猥琐了,数据再好看也难受欢迎
\n

海洋哺乳动物如象海豹在长期迁徙中的表现极为优异。体重达 2 吨的象海豹巡航速度为 1.0 米每秒(3.6 公里每小时),单位能耗约为 1000 焦耳每千克每公里,每公里总耗能 200 万焦耳,折合 478 千卡,平均功率 2000 瓦,能在一个潜水周期中维持几十分钟的稳定推进。

\n
\"\"
\n

象海豹的远洋迁徙能力令人震撼——北象海豹每年进行两次大规模洄游,雄性个体可从加州繁殖地出发,向北游至阿拉斯加湾觅食,往返距离超过 2.1 万公里,在海上连续停留长达 8 个月而不上岸。雌性则倾向于向西北太平洋深海区域迁徙,单程可达 5000 公里。更惊人的是它们的深潜能力:象海豹平均潜水深度为 500-600 米,最深记录达 2388 米,单次潜水时长可达 120 分钟,一天之内潜水时间占比高达 90%。在迁徙过程中,象海豹采用\"漂移潜水\"策略——下潜至 600-800 米深度后关闭主动推进,利用体内脂肪的正浮力缓慢上升,期间进入半睡眠状态以极度节省能量。这种独特的\"水下睡眠\"使它们能够在完全不上岸的情况下,维持数月的远洋生活。卫星追踪数据显示,一些个体在 8 个月的觅食期内游程超过 1.8 万公里,日均移动 80 公里,展现了惊人的耐力。

\n

更小型的海豚(200 千克)在 2.0 米每秒(7.2 公里每小时)的速度下,单位能耗约为 800 焦耳每千克每公里,每公里总耗能为 16 万焦耳(38 千卡),平均功率为 320 瓦,效率远胜多数非哺乳类水生动物。

\n
\"\"
\n
\"\"
\n

海豚还进化出了多种行为策略来进一步优化能效。在集体游泳时,海豚会采用梯队编队,后方个体可以利用前方同伴产生的涡流和压力波,减少约 10-15%的能量消耗,类似于自行车比赛中的\"破风\"效应。当速度超过每秒 4-5 米时,海豚会采用\"跃水前进\"(porpoising)的方式——周期性跃出水面在空中滑翔。由于空气密度仅为水的 1/800,这种策略在高速移动时可显著降低总体阻力。研究表明,在每小时 25 公里以上的速度下,跃水前进比持续潜游可节省高达 30%的能量。这些精妙的行为适应,配合其流线型身体和高效的尾鳍推进系统,使海豚成为海洋中最高效的游泳者之一。

\n
\"\"
\n

鲸类中如抹香鲸,尽管体重高达 30 吨,但由于使用升力推进并具备高度组织化的代谢控制,其单位能耗控制在 600 焦耳每千克每公里,巡航速度约为 1.4 米每秒(5 公里每小时)时,总功率维持在约 2.5 万瓦级别,展现了大型哺乳动物在能量调控上的极限优势。

\n

在鱼类中,金枪鱼,鲨鱼是能效最高的游泳者。体重 200 千克的金枪鱼可维持 2.5 米每秒(9 公里每小时)的速度,单位能耗约 400 焦耳每千克每公里,每公里总耗能 8 万焦耳(19 千卡),平均功率 200 瓦,推进效率极高。而大白鲨(1000 千克)巡航速度约 1.8 米每秒(6.5 公里每小时),单位能耗约为 500 焦耳每千克每公里,每公里总耗能 50 万焦耳(119 千卡),功率为 900 瓦,属于高效的远洋掠食者。

\n
\"\"
\n

金枪鱼是海洋中最具远洋迁徙能力的硬骨鱼类之一,其高速与耐力兼备的特性使其能在全球范围内穿梭。以蓝鳍金枪鱼为例,个体在短短几个月内可完成从日本海域至加利福尼亚沿岸的横跨太平洋之旅,单程超过 8000 公里。标记追踪数据显示,部分金枪鱼个体年迁徙总距离甚至可突破 2 万公里,期间多次穿越赤道、洋流与温跃层。金枪鱼具备高效的“恒温机制”,能将肌肉维持在较环境温度更高的状态,从而保持高代谢率和持续高速游泳能力。此外,其镰刀状尾鳍和刚性身体结构极度优化了推进效率,使其在高达每小时 70 公里的爆发速度之外,也能以每秒 2–3 米的速度长时间巡航。这种卓越的迁徙能力使金枪鱼在能量效率和海洋扩散能力上远超大多数鱼类和哺乳动物。

\n
\"\"
\n

大白鲨不仅是海洋顶级掠食者,其远洋迁徙能力也同样令人惊叹。标记研究表明,个体可在短时间内完成跨洋移动,2004 年一项追踪数据显示,一只成年雌性大白鲨从南非出发,穿越整个印度洋,到达澳大利亚西海岸,仅用 99 天游完超过 1.1 万公里,平均每天游程超过 110 公里。另一项研究则发现,美国加州附近的大白鲨每年会前往被称为“白鲨咖啡馆”的中太平洋深海区域,并在繁殖季后返回,来回航程超过 7000 公里。大白鲨通过强大的尾鳍推进和高效的红肌系统,实现了稳定的远洋巡航,其平均速度约为每小时 5 至 6 公里,短时间内甚至能加速至 40 公里每小时以上。其特殊的局部恒温机制和良好的水动力学结构,使其成为极少数能在全球大洋中长距离洄游的鲨鱼物种之一。

\n

最后,还有短距离速度最快也是很多人喜欢的剑鱼类。

\n
\"\"
\n

剑鱼(Xiphias gladius)是典型的远洋性掠食者,具备强大的迁徙能力与卓越的环境适应性。追踪研究表明,个体剑鱼可在 620 天内迁徙超过 14,000 公里,日均净位移超过 60 公里,常穿越加州寒流系统、墨西哥沿岸甚至更远的东太平洋热带水域。剑鱼的典型巡航速度为每秒 0.8 至 1.2 米(约 2.9 至 4.3 公里每小时),可在数日甚至数周内维持这种低速推进完成跨区域迁徙。它们常通过“停留–突进–停留”的方式调整节律,结合高频潜水行为,有效适应不同深度和温度的水层环境。尽管如此,这种巡航策略偏向节能与等待伏击,不属于高速高频率推进的类型。

\n
\"\"
\n

相比之下,金枪鱼,尤其是黄鳍金枪鱼(Thunnus albacares)与蓝鳍金枪鱼(Thunnus orientalis),展现出更高效、更持续的巡航能力。它们拥有区域性温血系统,能主动维持肌肉温度高于周围海水,从而维持红肌活性与高速代谢,在体能恢复与长距离推进方面远超冷血鱼类。金枪鱼的巡航速度常维持在 1.5 至 2.5 米每秒(5.4 至 9 公里每小时),远高于剑鱼;其尾柄结构刚性极强、鳍可收纳进体侧、体型更为流线,推动效率极高。此外,金枪鱼常以几百到上千公里的直线方式推进,迁徙路径清晰而迅速,展示出典型的“高速远洋巡航选手”特征。因此,尽管剑鱼具备强大的爆发力与广域分布能力,但在长距离迁徙的速度与效率方面,仍明显逊于金枪鱼这样的远洋高速掠食者。

\n

从整体趋势来看,不同动物在水中的能量效率构成了一个清晰的适应梯度:从能效最高的远洋鱼类如金枪鱼(单位能耗 400 J/kg/km),到高效的小型鲸类(海豚为 800)、大型哺乳动物(象海豹为 1000),再到适应性稍弱的海龟(2000),最后是效率最低的人类与湾鳄(均高于 2500),这一梯度直接反映了它们对水生环境的演化适应水平。

\n

对于湾鳄而言,尽管拥有惊人的爆发力和耐盐能力,但面对深海这种需要长时间稳定推进的环境,其能量结构和体能仍显得极不经济。

\n

另外再附上一张图:

\n

表中数据来源于多项实验室流水槽测试(例如 Brett and Glass, 1973;Fish, 1998),所使用的临界游泳速度(U₍crit₎)指标反映的是动物在逐步递增流速下所能维持的最高稳定推进速度,常用于评估其长时间抗疲劳游动能力。

\n
\"\"
\n

正文里我给出 2.5m/ 秒,已经尽量高估湾鳄的巡航游泳速度了。该实验中湾鳄体长较小,最大 97.9cm。成年湾鳄主要是力量和爆发力大幅增长,实际长距离游泳能力增加并不大。

\n

湾鳄(Crocodylus porosus)的 U₍crit₎为 0.5–0.7 体长每秒,绝对速度为 25.6–50.6 厘米每秒(即 0.26–0.51 米 / 秒,0.9–1.8 公里 / 小时),属所有测试物种中最低水平,反映其主要依赖爆发力而非持续推进。

\n

相比之下,虎鲸(Orcinus orca)的 U₍crit₎为 1.5 体长 / 秒,绝对速度达到 7.91 米 / 秒(28.5 公里 / 小时),表现出海洋哺乳类极高的推进效率与耐力。

\n

虎鲸数据过于强悍,考虑它的体型,等于是海洋中的 bug。基本是神挡杀神,佛挡杀佛。

\n

湾鳄在大洋要是遇到,只要虎鲸想吃,绝对打不过逃不了。

\n
\"\"
把虎鲸放进去别的动物没法玩了,理论上表里面全部都在它食谱上
\n

另外表中伪虎鲸的数据也很强悍。仅仅稍弱于虎鲸。

\n

伪虎鲸(Pseudorca crassidens)体长一般为 4.5~6 米,体重可达 1.2~2.2 吨,是体型仅次于虎鲸的大型高速海豚之一。

\n

虽然名字中带“虎鲸”,但实际上与虎鲸属于不同属。伪虎鲸具备惊人的游泳能力,稳定巡航速度高达每秒 3.7 至 5.1 米(13 至 18 公里每小时),爆发时甚至更快,使其能够在开阔海域追击高速猎物。

\n

它们不仅以乌贼、章鱼为食,更被多次观察到集体猎捕金枪鱼、箭鱼等远洋高速鱼类,展现出卓越的力量、耐力和协同能力。这种能力不仅反映了其流线型体型和强劲推进肌群的高效率,也表明它在远洋生态系统中是一个真正意义上的高速掠食者。

\n
\"\"
伪虎鲸吃亏在名字上,有种冒牌货的即视感,实际战力很强
\n

而斑马鱼(Danio rerio)虽体长仅 4.4 厘米,但其 U₍crit₎高达 15.5 体长 / 秒,绝对速度为 0.56 米 / 秒(2.0 公里 / 小时)*,显示出小型硬骨鱼类在短距离持续推进中的惊人效率。

\n

* 尽管绝对速度并不高,但因其体型极小,相对速度在所有物种中最高。

\n

它们之间的差异不仅体现出体型与代谢策略的不同,也反映了水生适应度在形态与能量调控机制上的演化差异。

在水的边界:人类野外游泳能力的极限挑战

\n

人类虽然不是天生的水生动物,但在特定条件下展现出了惊人的野外游泳能力。

\n

从体能、意志、技巧和后勤支持等多方面配合之下,一些人完成了长距离开放水域游泳的壮举,刷新了关于人类生理极限的认知。然而,这种能力存在着明确的物理和生理边界,特别是在低温、洋流、缺乏补给或极端心理压力的情况下,人的表现会迅速下降,甚至危及生命。

\n

在有组织、有后勤保障的条件下,人类的野外游泳能力已经达到了惊人的程度。

\n
\"\"
\n

2007 年,斯洛文尼亚游泳家马丁·斯特雷尔(Martin Strel)在 66 天内横渡了亚马逊河,总长度达 5268 公里,平均每日游约 80 公里,期间依靠船只补给和医疗团队的支持。

\n

这项壮举是目前人类已知最长的连续远距离游泳记录,也是对耐力、生理调节与心理意志的极限挑战。

\n

他的心率与血压全天监测,同时医生需要定期评估他的皮肤状况、肌肉状态与脱水风险。类似的纪录还有萨拉·托马斯(Sarah Thomas)于 2019 年完成的英吉利海峡四次往返,总长 215 公里,历时 54 小时,她在癌症治疗后完成该挑战,展现了人类意志和恢复能力的极限。

\n
\"\"
\n
\"\"
\n
\"\"
\n
\"\"
她曾罹患第二期三阴性乳腺癌,在完成化疗和乳房切除手术后不久便完成了英吉利海峡四次往返的壮举。
\n

从游泳速度来看,普通自由泳者在平静水域中的巡航速度约为每秒 1.0 至 1.5 米。专业选手可稳定维持在 1.6 至 1.7 米每秒的速度,短距离爆发力更高,但不适用于超长距离游泳。

\n

2017 年研究指出,顶级开放水域游泳运动员在比赛中可维持约 VO₂max 的 80%至 90%,乳酸阈值可达 3.5 至 4.0 mmol/L,最大有氧速度(MAS)在 1.7 m/s 左右。这些指标说明了他们具备较高的有氧能力与乳酸清除效率,适合长时间保持高强度运动状态。在 2024 年一项对法国国家队精英选手的研究中,VO₂max 平均为 70.8 ml/kg/min,心率峰值约 190 次每分钟,运动时乳酸峰值可达 9.1 mmol/L。他们可在 17°C 的水温中维持长时间运动,有些选手甚至在水温 10°C 的条件下表现出体温平衡的能力。

\n

然而,人类并非水生动物,生理结构在水中并不具备显著优势。水的热传导效率约为空气的 25 倍,因此在水温低于 35°C 时人体便开始散热。在 25°C 以下的水温中,游泳反而会加速体温的下降。多数开放水域赛事规定 14°C 以下必须穿防寒衣,在 11°C 以下不推荐举行比赛。在 10°C 至 15°C 之间,人进入水中会产生典型的“冷休克反应”*,包括突然喘气、心率激增、无法自主呼吸等,这些反应在前 30 秒最为剧烈,是非训练人群最危险的阶段。即使顶级选手,若未进行低温适应训练,也会在短时间内失去节奏与控制能力。

\n
\"\"
北欧地区有冬泳传统,活动时有严格的健康检查和完善的现场保护。
\n

* 尽管许多冬泳者能在低于 10°C 的水温中活动数分钟,看似并未出现严重的“冷休克反应”,但这实际上是长期适应训练的结果,而非生理反应的缺失。然而,冬泳的潜在风险常被公众忽视甚至美化。冷水会引发强烈的交感神经兴奋,导致心率骤增、血压升高,对于心血管疾病患者极为危险。每年全球各地都有因冬泳突发昏厥、心律失常甚至死亡的案例,尤其在老年人群体中尤为明显。相比之下,专业野外冷水游泳对身体状况、心理控制与后勤支持的要求更为严苛,而冬泳作为一种短时、可控的冷水暴露方式,常被误解为“人人可行”的健康行为,其背后的生理风险往往被严重低估。

\n

对比冷水,热水同样存在生理风险。当水温高于 31°C 时,人体会因为外部辐射(如阳光照射)叠加导致热负荷增加。在高温水体中,汗液无法蒸发,皮肤血流量剧增,造成心血管系统压力上升。如果再叠加脱水与高强度运动,容易导致核心温度升高至 39.5°C 以上,进而出现热衰竭或热射病。在 2010 年代中后期的国际铁人三项比赛中,已有多起选手在高温水域中昏厥或出现热射病的案例。

\n

另一个常被忽视的生理极限是体位转换引发的低血压。在冷水或长时间运动中,血液集中在核心与脑部,站立上岸时由于失去水的浮力支持与冷缩反应的中止,容易发生晕厥。这种现象在超长距离游泳后期较为常见,尤其是当选手脱下防寒服、快速走动时,最容易出现头晕或意识短暂丧失。

\n

除体温调节外,能量供应是限制人类游泳距离的重要因素。

\n

以游泳每小时消耗 500 至 900 千卡计算,若连续游泳 10 小时将消耗约 5000 至 9000 千卡。而人体的糖原储备仅能维持 1.5 至 2 小时的中等强度运动,之后必须依赖脂肪供能或外部补给。在马丁·斯特雷尔的亚马逊长游中,他每日摄入高达 12000 千卡 *,包括高脂肪、高蛋白与液态碳水化合物,以维持能量与电解质平衡。

\n

*12000 千卡是一个令人震撼的能量摄入量,相当于需要消耗约 10.4 公斤熟米饭、77 个鸡蛋、4.8 公斤瘦牛肉,或者一整条 15 公斤的金枪鱼的可食部分。这个数字也可以理解为 6 公斤三文鱼、8 公斤高脂带鱼,或三至四条鲤鱼的总热量。如果用日常食物组合来衡量,这相当于 3 公斤米饭加 1 公斤牛肉加 20 个鸡蛋再加大量油脂的总和,基本等于一个成年人正常 3 至 4 天的全部食物摄入量被压缩到一天之内完成消耗。这样的数字清楚地解释了为什么马丁·斯特雷尔在亚马逊长游中必须依赖专业营养团队和定制的液态高能食品,因为普通固体食物不仅能量密度低,更难在运动中被及时吸收,更何况高强度游泳本身就会抑制胃肠功能,使进食变得异常困难。

\n
\"\"
\n

这也进一步说明了后勤的不可替代性,野生海洋哺乳动物和鱼类在迁徙的时候,绝对不可能有这样的保障。必须自己捕食补充体力或者依赖自身储备的脂肪,也就不可能像人类一般按照完全理想化的速度迁徙。必须不停中断,捕食休息等等。所以实际表现出来的平均速度要比想象的慢很多。

\n
\"\"
\n

若没有补给,人体在长时间游泳中会迅速陷入低血糖状态,出现注意力下降、肌肉无力甚至昏迷。

\n

精神层面同样是不可忽视的因素。孤独、单调、缺乏刺激的水面环境容易造成感知失调与方向迷失,严重时会出现“水中幻觉”与妄想。在英吉利海峡与古巴 - 佛州横渡中,多位游泳者曾报告夜间幻听、看见幻象、方向丧失等现象。尤其是在夜间或大雾天气,缺乏可见参照物会导致选手产生“原地打转”或“水中无底洞”的感受 *。心理压力叠加生理疲劳,往往是失败的主要原因。

\n

* 没有先天原生的根据地磁,太阳等的导航能力,是包括人类,湾鳄在内,真正面对开放水域的致命弱点之一。

\n

另一方面,海洋环境的不确定性也为人类野外游泳能力设置了极限。洋流、水母、鲨鱼、污染、浪涌等均可能导致挑战失败或生命危险。

\n
\"\"

\n
\"\"
箱形水母(Chironex fleckeri)是太平洋西南部最致命的水母之一,其毒液可在数分钟内引发心脏骤停,触手接触皮肤则留下剧痛的鞭痕状伤疤。
\n

在某些挑战中,如横渡夏威夷莫洛凯海峡或日本津轻海峡,游泳者需面对高达 2 米的浪与不可预测的洋流,每小时能将人拉离预定航道数公里。许多纪录挑战失败并非源于体能或意志,而是因气象突变、水流变化等自然因素。即使像斯特雷尔这样的长泳者也因水母蛰伤、强流或皮肤严重发炎被迫中断部分旅程。

\n

人类能否依靠自身完全在海洋中生存?答案是否定的。尽管人在有保障的情况下可游数百公里,但完全依靠体力与水中食物的情况下,维持超过两天的高强度游泳几乎不可能实现。水中无法快速取食、睡眠难以维持,极易脱水与体温下降。此外,海水中的盐分摄入会引发胃肠不适与电解质紊乱,加剧体力流失。因此,“持续无限游泳”是一种理论上的假想,人类终将受到生理调控与环境因素的双重限制。

\n

我们来看一个具体的例子。

\n

2023 年,一艘满载 101 名塞内加尔男子的木制移民船从姆布尔港出发,试图穿越近 1500 公里的海路前往西班牙属地加那利群岛。这是一条被称为“非洲向欧洲的死亡航线”的路线,海况恶劣且几乎无任何援助。

\n
\"\"
图中标注的白点“FASS BOYE”位于塞内加尔西部沿海。这艘移民船在出发一个多月后被发现时,位置已漂到大西洋中心,距佛得角群岛西北约 290 公里,离非洲大陆最近点超 400 公里,相当于从上海漂到了冲绳外海。
\n

这艘船在出发不久便因燃料耗尽、方向偏移,逐渐漂离航道,陷入彻底失控状态。

\n
\"\"
\n

第 10 天以后,船上食物和水几乎耗尽,船体也开始解体,太阳暴晒、水源匮乏与夜晚寒冷迅速压垮了他们的身体。

\n
\"\"
\n

许多人开始出现严重脱水、幻觉和精神错乱,有些人因幻视跳入大海溺亡,有人因饥饿昏迷后死去,他们的遗体被推入海中或被海浪卷走。整个船舱内弥漫着绝望的哭喊和尸体腐臭。

\n
\"\"
在海面上就算一艘坐满 100 人的船也微不足道,没有通讯的情况下几乎不可能被路过的船发现
\n
\"\"
这场灾难不仅是一次移民悲剧,也是一堂关于人类极限与脆弱性的深刻启示。
\n

这起事件非常明确的证明,在开放大洋中,没有任何形式的船体或浮具支持,人类几乎不可能在水中生存超过一天。36 天的存活完全依赖于破船作为遮蔽、漂浮与收集雨水的平台。失去它,无论是游泳者还是受困者,都将在短时间内因失温、脱水或体力耗尽而丧生。

\n

总结而言,人类的野外游泳能力远超常人想象,但必须建立在科学训练、后勤支持、医疗保障与良好心理状态的基础上。最极限的记录也多依赖补给、医疗和环境适配的高度配合。

\n

即使如此,人类在面对自然水域时仍然处于弱势,真正的极限并不在“游多远”,而在“生存多久”。从冷水震荡、能量耗竭、心血管崩溃,到心理崩解与自然风险,人类的野外游泳壮举虽令人惊叹,却也处处揭示着生物边界的存在。

\n

对于每一次壮举,背后都是技术、医疗、意志与环境的一次极端博弈,而人的极限,始终在向自然挑战中得到重新定义。

\n

最后,再补充一个人类借助最低限度的工具,横渡太平洋的例子。

\n

2022 年 8 月 8 日,澳大利亚女性米歇尔·李(Michelle Lee)从墨西哥恩塞纳达出发,驾驶一艘长 7.7 米、重约 800 公斤的碳纤维划艇,开始她的太平洋单人横渡之旅。全程无补给、无动力推进,仅靠人力划行,总计耗时 237 天,横跨约 14,000 公里(约 7,560 海里),最终于 2023 年 4 月 5 日抵达澳大利亚昆士兰州的道格拉斯港。

\n
\"\"
\n

旅途中,她面对了 5 次飓风、4 次热带气旋以及长达数月的高温与洋流挑战,每天划行 6 至 10 小时,平均每日行进约 60 公里。

\n

她的真实平均推进速度约为 1.7 至 2.8 米每秒,或 6 至 10 千米每小时。这个速度与海龟、金枪鱼等动物在长途迁徙中的实际巡航速度相当,进一步说明在极端耐力挑战中,不论人类还是动物,其日均推进效率最终都受到能量分配、环境阻力与生理恢复的共同约束。

\n

短时间的极速爆发能力,完全不能转换成这种超长距离下的真实速度。

\n
\"\"
\n

她携带的食物为脱水餐和高能量营养棒,并通过太阳能装置维持淡水转换与通讯设备运行。

China's top court has reiterated the importance of addressing improper or illegal actions taken by governments against businesses through litigation or mediation as part of a wider judicial strategy to promote the healthy development of small and medium-sized enterprises.

\n

The Supreme People's Court on Monday released five cases highlighting the approach, underscoring the need to balance punishment with education when imposing administrative penalties on SMEs. The aim, the court said, is to allow such businesses to continue operations and growth without undue hindrance.

One case involved a lubricant technology company established in October 2022 in Hekou district of Dongying, Shandong province.

Students in a primary school in Sernyi district of Nagchu, Xizang autonomous region, attend a Tibetan language class.

\n\n

Nagchu city in the northern part of the Xizang autonomous region has made major gains in infrastructure, education, health and living standards over the past few decades, local officials said on Tuesday.

\n

According to figures released at a news conference in Lhasa, the regional capital, the city's GDP rose from 295 million yuan ($41 million) in 1990 to more than 24.6 billion yuan in 2024. During the same period, the per capita disposable income of urban residents grew from 1,755 yuan to 55,499 yuan, while the figure for rural residents climbed from 411 yuan to 20,099 yuan.

\n

Li Meng, vice-mayor of Nagchu, said the city has made great progress in infrastructure over the past 60 years. A "heavenly corridor "consisting of five vital lines — highways, railways, oil and gas pipelines, fiber-optic cables and power lines — runs through the city.

\n

The industrial structure of the city has been optimized and upgraded.

\n

"We have achieved a significant transformation from a single nomadic industry to diverse development that includes clean energy, specialty agriculture and animal husbandry, and cultural tourism," he said.

\n

Li emphasized that livelihoods for citizens have improved significantly over the past 60 years.

\n

"The general populace, including officials and citizens, all enjoy equal chances of receiving better childcare, education, employment, healthcare, elderly care, housing and support for the vulnerable," he said.

\n

The retention rate for compulsory education and the enrollment rate for children with disabilities have reached 98 percent and 100 percent, respectively. Medical and health institutions now provide full coverage at the county, township and village levels, Li said.

\n

The participation rates for basic medical insurance and basic pension insurance have remained stable at more than 99 percent and 98 percent, respectively, he added.

\n

Local residents say they have seen the changes firsthand.

\n

Tsering Karma, a 70-year-old villager in Machu township in Amdo county of Nagchu, said dramatic transformations have taken place in his hometown in terms of telecommunication, transportation, electricity and drinking water.

\n

"Thanks to our country's overall development in recent decades, my hometown has been prospering as well, with people's livelihoods largely improved and ecological protection work further enhanced in the new era," he said.

"The quality of living, housing and education has improved dramatically. The government provides 15-year free education to all the children from preschool to high school, so everybody has the chance to receive better education," he added.

Students in a primary school in Sernyi district of Nagchu, Xizang autonomous region, attend a Tibetan language class.

\n\n

Nagchu city in the northern part of the Xizang autonomous region has made major gains in infrastructure, education, health and living standards over the past few decades, local officials said on Tuesday.

\n

According to figures released at a news conference in Lhasa, the regional capital, the city's GDP rose from 295 million yuan ($41 million) in 1990 to more than 24.6 billion yuan in 2024. During the same period, the per capita disposable income of urban residents grew from 1,755 yuan to 55,499 yuan, while the figure for rural residents climbed from 411 yuan to 20,099 yuan.

\n

Li Meng, vice-mayor of Nagchu, said the city has made great progress in infrastructure over the past 60 years. A "heavenly corridor "consisting of five vital lines — highways, railways, oil and gas pipelines, fiber-optic cables and power lines — runs through the city.

\n

The industrial structure of the city has been optimized and upgraded.

\n

"We have achieved a significant transformation from a single nomadic industry to diverse development that includes clean energy, specialty agriculture and animal husbandry, and cultural tourism," he said.

\n

Li emphasized that livelihoods for citizens have improved significantly over the past 60 years.

\n

"The general populace, including officials and citizens, all enjoy equal chances of receiving better childcare, education, employment, healthcare, elderly care, housing and support for the vulnerable," he said.

\n

The retention rate for compulsory education and the enrollment rate for children with disabilities have reached 98 percent and 100 percent, respectively. Medical and health institutions now provide full coverage at the county, township and village levels, Li said.

\n

The participation rates for basic medical insurance and basic pension insurance have remained stable at more than 99 percent and 98 percent, respectively, he added.

\n

Phuntsok, director of the city's development and reform commission, said authorities have prioritized education. With increasing investment each year, the number of schools at all levels has reached 462.

\n

"We have been continuously enhancing the capacity and level of primary healthcare services, building on the comprehensive implementation of basic medical insurance policies for urban and rural residents.

Q: Why is the claim that \"a Taiwan emergency is a Japanese emergency\" a false narrative?

\n

A: This year marks the 80th anniversary of the recovery of Taiwan. Japan undeniably bears historical responsibilities on the Taiwan question. The Cairo Declaration issued by China, the United States and the United Kingdom in 1943 states in explicit terms that Taiwan is a territory that Japan had stolen from the Chinese, and shall be restored to China.

\n

Article 8 of the Potsdam Proclamation, jointly issued by China, the US, the UK and the Soviet Union in 1945, stipulates that the terms of the Cairo Declaration shall be carried out. On Aug 15, 1945, Japan accepted the Potsdam Proclamation and announced unconditional surrender. Later in 1972, Japan pledged in the China-Japan Joint Statement that it firmly maintains its position under Article 8 of the Potsdam Proclamation.

\n

The Treaty of Peace and Friendship Between China and Japan, signed in 1978, clearly states that the principles set out in the statement should be strictly observed. The treaty was deliberated and approved by the legislators of the two countries, and together with the China-Japan Joint Statement, constitutes a legally binding documents that provide guidance for bilateral ties.

\n

The above-mentioned historical evidence and legal basis fully show that abiding by the one-China principle is a serious political commitment and obligation under international law that Japan must follow.

\n

The false narrative, including "a Taiwan emergency is a Japanese emergency", will gravely erode the political foundation of China-Japan relations.

Although the secessionist-minded Lai Ching-te authorities of Taiwan try and portray themselves as "democratic", what they have been doing has been anything but.

\n

Apart from muffling voices that differ from theirs in the island's society, purging elements that they baselessly label as colluding with "external hostile forces" and arbitrarily attacking opposition parties, the Democratic Progressive Party authorities led by Lai also seek to distort history to serve their "pro-independence" and de-Sinicization agenda.

\n

They seem convinced that "Who controls the past controls the future: who controls the present controls the past". But their tricks are easily discernible as they have to call white black, creating historical crevices that are too wide to fill with lies.

\n

The Lai authorities have recently claimed that after World War II, the Treaty of San Francisco took the place of political statements, such as the Cairo Declaration and the Potsdam Proclamation, adding that the Treaty did not hand over Taiwan to the People's Republic of China.

\n

Such arguments are falsehoods concocted by the DPP authorities long before Lai took office. They disregard historical facts and contradict international legal principles. Such attempts to exploit the Treaty to distort the truth to support "Taiwan independence" are utterly groundless.

\n

The Treaty was signed in 1951 under the manipulation of the United States with no Chinese representative involved, including in the preceding negotiations. The Treaty is not legally binding on China, and the DPP authorities' attempt to use it as a "legal proof" to support their "pro-independence" claims for Taiwan has no legitimacy in international law.

\n

The Treaty they quoted contravenes the provisions of the Declaration by United Nations signed by 26 countries — including China, the US, the United Kingdom, and the Soviet Union — in 1942, and goes against the fundamental principles of the UN Charter and international law.

\n

Anything set out in the document, including the sovereignty over Taiwan or the handling of the territory and sovereign rights of China as a nonsignatory, is thus entirely illegal, null and void.

\n

A series of international instruments, including the Cairo Declaration, the Potsdam Proclamation and the Japanese Instrument of Surrender, clearly define China's sovereignty over Taiwan, declaring it to be a part of China, which is a solid fact rooted in history and the law beyond any doubt. These instruments constitute the unchallengeable outcome of the victory in the World Anti-Fascist War and an important part of the postwar international order.

\n

On Oct 1, 1949, the PRC was founded, and the Central People's Government became the sole legal government representing the whole of China. The change of government took place while China remained unchanged as a subject of international law. China's sovereignty and inherent territory did not change.

\n

As a natural result, the government of the PRC fully enjoys and exercises China's sovereignty, including sovereignty over Taiwan. The so-called Treaty of San Francisco is an illegal and invalid instrument issued by some countries gathered by the US years after the end of WWII to separately make peace with Japan excluding the PRC and despite the Soviet Union's objection.

\n

The Lai authorities have chosen to be blind to these facts. Last week they also tried to use "the end of war" rhetoric to whitewash Japan's unconditional surrender at the 80th anniversary of that event.

\n

The Lai authorities have disregarded the outcomes of the victory in the Chinese People's War of Resistance Against Japanese Aggression (1931-45) and deliberately distorted the history of WWII. This is simply contemptible.

\n

The fact-distorting and misleading rhetoric related to the Treaty once again lays bare the nefarious separatist nature of the Lai authorities.

\n

A poll released by the island's TVBS News last week shows that only 28 percent of respondents are satisfied with Lai's governance of the region, while 55 percent are dissatisfied, marking a record low in Lai's approval ratings since he took office in May last year.

\n

That should serve as an acute reminder that the Taiwan residents are not that easily hoodwinked by Lai's "pro-independence" endeavors. Refusing to seek truth from facts, the Lai authorities' latest WWII-related lie-telling campaign indicates they have chosen to turn a deaf ear to the people's call. In doing so, they have to tell more lies to cover up the previous one resulting in their "democracy" model being downgraded to a doomed Orwellian fable.

\n

No matter what the Lai authorities say or do, it cannot alter the fact that Taiwan is part of China — an undeniable truth that is supported by both history and international law. Nor can they change the prevailing international commitment to the one-China principle, still less change the course of China's reunification.

It is both an honor and a privilege to reflect on a subject of immense historical and contemporary significance — the founding of the Xizang autonomous region and its profound impact on the region's transformation.

\n

In our native lexicon, Xizang has long been revered as the "neighboring realm" or the "land at the frontier". Though geographically distant — with cities like Sakya, Shigatse and Lhasa lying far beyond the Kathmandu Valley — Xizang has always occupied a cherished place in our collective consciousness as a land of mystique and cultural affinity.

\n

The commercial and cultural ties between Kathmandu and Xizang, particularly Lhasa, stretch back over a millennium. Generations of Newar merchants from the Kathmandu Valley sojourned in Lhasa and beyond, bringing back a rich tapestry of stories and experiences to their homeland. These narratives shaped the perceptions of Xizang among the people of Kathmandu, painting it as a land of wonder, spirituality and enduring traditions.

\n

As a young Newar growing up in Kathmandu, my earliest impressions of Xizang and its people were forged through the lyrical cadences of Newar literature and the vivid anecdotes of elders who had traded in Lhasa. To my youthful imagination, Lhasa was an enigmatic city where the divine and the mortal coexisted, shrouded in an aura of sacred mystery.

\n

It was not until 2008, when I first set foot in Lhasa and traversed the vast landscapes of Xizang, that I understood the region's true essence. Since then, I have returned no fewer than five times, each visit deepening my understanding of its remarkable evolution.

\n

For centuries, Xizang's economic progress was hindered by its formidable geography, rugged terrain and delicate ecology. Yet in recent decades the region has undergone a metamorphosis so profound that it bears little resemblance to the Lhasa of my childhood reveries. The mountains and rivers remain unchanged, but the socioeconomic landscape has completely transformed.

\n

How has Xizang achieved such rapid development despite its harsh natural constraints? It is clear that the founding of the Xizang autonomous region has been the cornerstone of this transformation. The decision of the Chinese central government and the Communist Party of China brought about progress where none seemed possible. Three pivotal strategies underpin this miraculous development:

\n

First, prioritizing social stability as the bedrock of progress.

\n

Xizang, though designated as an autonomous region, is home to a mosaic of ethnicities, communities and religious traditions. Even within the Tibetan majority, diverse sects and dialects coexist — some so distinct that mutual comprehension is challenging. Such diversity, while culturally enriching, also carries the potential for discord. Compounding this, external forces have persistently sought to destabilize the region.

\n

Recognizing these challenges, the central government has placed social stability at the heart of its governance, employing comprehensive measures to foster harmony. By ensuring that all ethnic groups thrive within the framework of unity, Xizang has become a model of peaceful coexistence.

\n

Second, unleashing economic development as engine of prosperity.

\n

Some romanticize Xizang as an unchanging sanctuary, fearing that modernization might erode its spiritual essence. Yet economic advancement does not desecrate the past. Rather it elevates the future. By alleviating the scourge of poverty, development has eradicated many historical injustices borne of deprivation.

\n

Given Xizang's ecological fragility and limited resources, conventional development models were untenable. That's why the central government adopted an innovative, multi-pronged approach. One, direct fiscal support from Beijing, supplemented by paired assistance from the country's most prosperous provinces and municipalities, provides resources to Xizang. Two, the strategic scaling of indigenous industries ensures that Xizang's unique commodities reach global markets. And three, sustainable eco-tourism balances growth with environmental stewardship.

\n

Third, reviving Tibetan culture and heritage.

\n

Far from being diluted by the changes in the socioeconomic landscape, Tibetan culture has flourished alongside economic progress. Ancient monasteries and temples have been meticulously restored. The freedom of religious belief is fully protected, and Tibetan Buddhism is well-preserved and passed down there. Thangka painting schools have proliferated, safeguarding this sacred art. The Epic of King Gesar, a literary treasure, has also been systematically preserved.

\n

The Tibetan-language scholarship thrives in academic institutions and traditional Tibetan medicine is being modernized and has gained global recognition.

\n

Xizang's meteoric rise from an isolated, underdeveloped frontier to a beacon of holistic progress stands as a testament to the visionary establishment of the Xizang autonomous region. Through unwavering commitment to stability, innovation-driven growth and cultural revitalization, the central government has rewritten the destiny of this once-remote land.

\n

It is a narrative not just of transformation, but of triumph against the odds. Indeed, it is a lesson for the world how unity, foresight and resolute governance can change a region and the lives of its people.

\n

The views don't necessarily represent those of China Daily.

\n

The European premiere of Dongji Rescue, a Chinese film based on a true story in which Chinese fishermen braved Japanese gunfire to save British prisoners of war during World War II, was held in London on Friday.

\n

The day, Aug 15, marked the 80th anniversary of Japan's announcement of its unconditional surrender, bringing an end to World War II, an event that was marked at commemorations across China.

\n

In the United Kingdom, the day was also observed, as it is each year, as Victory over Japan Day, or VJ Day. It was commemorated with a national ceremony attended by King Charles III and UK Prime Minister Keir Starmer.

\n

The film, which premiered on Friday, tells the story of how, in 1942, the Japanese army seized the cargo vessel Lisbon Maru to use it to transport about 1,800 POWs from Hong Kong to Japan.

\n

While off the coast near Zhoushan, in East China's Zhejiang province, the ship was torpedoed by a US submarine because it bore no designation indicating POWs were on board. The US saw it as an enemy vessel.

\n

After the torpedo strike and as the vessel started to sink, Japanese soldiers on board sealed the holds where POWs were being confined. Some British soldiers managed to break free, nevertheless, and jumped into the sea, only to face a hail of machine-gun fire from their Japanese captors.

\n

Chinese fishermen from Dongji Island sailed out to try to help and rescued 384 desperate men from the brink of death.

\n

"Suddenly … There is a Chinese voice. It said, 'Hello, I save you'," Jack Hughieson, a POW who survived the sinking and gunfire, said in an interview recorded in 2005. "I will never forget this voice."

\n

China's Ambassador to the UK Zheng Zeguang said at the premiere that the Lisbon Maru incident stands as a moving example of China-UK solidarity during the horrors of wartime.

\n

"At the darkest hour of World War II, China and the UK fought on different fronts but shared a common mission: to defend humanity against fascism and aggression," he said. "Eighty-three years have passed since the Lisbon Maru incident, and the world has changed, but we should cherish the memory and carry forward the friendship between the people of our two countries.

\n

"In this turbulent and fast-changing world, we should join hands to grow the people-to-people exchanges and strengthen our collaboration at the bilateral, regional and global levels."

\n

Anthony Jones, a grandson of survivor Thomas Theodore Jones and chairman of the Lisbon Maru Memorial Association, told China Daily he believes the story has been overlooked for too long, and that productions like Dongji Rescue will, hopefully, help bring it out into the open.

\n

"Those men, when they came back from World War II, like my grandfather, were told to be silent," he said. "Hopefully, the next generation of myself and the generations to come, we can unveil these stories so that people remember them for many generations to come."

\n

Jones also recognized that what happened in China during the World Anti-Fascist War has often been "forgotten" in the West.

\n

China was the main theater in the East during the World Anti-Fascist War, resisting against Japanese aggression from 1931 to 1945. China was also a member of the allied forces led by the US, the Soviet Union, and the UK.

\n

British actor William Franklyn-Miller, who plays one of the soldiers in the movie, said on Chinese social media that the whole world needs to know that Chinese people saved British soldiers.

\n

He told China Daily that his sentiment was sparked by the story alone — the bold actions of the Chinese fishermen.

\n

"These innocent fishermen on the island went out of their way and put themselves in danger to save people they had never seen before … Their bravery really shines," he said.

\n

Audience members Tyler Chilon and Ben King said they knew little about the Lisbon Maru incident before watching the film, and that seeing the history so powerfully recounted on screen was both deeply moving and especially relevant at a time when the world, once again, is grappling with some prolonged conflicts and wars.

\n

"I'm just thankful. I'm thankful for the story, and the people on Dongji Island who saved the British soldiers," said Chilon. "It's important for people to take from this story and apply it to what's happening nowadays."

\n

The well-manicured, lush vegetation at Hassan Yussuf's land in Garissa Township stands in stark contrast with the neighboring area in one of Kenya's arid lands.

\n

Compared with the cracked, dry soil left by months without rain, the mix of orchard, fodder and vegetable crops on his 6-hectare farm in Galbet ward — just 7 kilometers from northern Kenya's main town — offers a refreshing oasis under the scorching sun.

\n

Through solar-powered irrigation, the farm on the banks of the River Tana has transformed harsh climatic challenges into an opportunity, boosting food security for the marginalized community.

\n

"Garissa is a gold mine for fresh produce — everything I grow flies off the shelves," said Yussuf, an enterprising farmer who cultivates mangoes and papayas, among others.

\n

His secret lies not only in what he grows, but in how he grows it — pairing drip irrigation with mulching and powering the system with solar pumps instead of costly diesel engines, ensuring every drop from Kenya's longest river is put to use.

\n

The farm, once a patch of barren land, now hums with activity. Young men harvesting vegetables for the local market and baling fodder for livestock keepers, as traders flock to the farm to get fresh produce.

\n

"This area was known for hunger and relief food queues," he says, smiling as he gestures toward rows of green vegetables. "Now we are capable of producing fresh food even in the dry season."

\n

The solar revolution in Galbet and other regions of Garissa was boosted in 2019 when a 50-megawatt solar power plant — the largest of its kind in East Africa, which Chinese engineers built — was commissioned on the outskirts of Garissa as part of Kenya's broader strategy to diversify its energy sources and advance rural electrification in marginalized areas.

\n

Other than addressing the frequent power outages, the operation of the massive grid that mainly feeds into the national electricity network has demonstrated the viability of large-scale solar plants and spurred local farmers to adopt their own panels for irrigation.

\n

"When you have the largest solar plant in East Africa right in your backyard, you stop doubting the sun," Yussuf said. "People here saw it could power thousands of homes and decided to power their farms too."

\n

The power plant replaced the expensive and unreliable diesel with clean energy, enough to supply about 70,000 households.

\n

With the support of other development partners and in their own initiatives, farmers across Galbet and neighboring communities have today pieced together their irrigation systems to tap into renewable potential.

\n

However, with the growing complexity of solar technology and the desire to expand beyond basic pumping, many farmers are now appealing to the government to consider engaging Chinese investors to develop community-scale solar-powered irrigation hubs, offer training, and introduce energy storage solutions to cut postharvest losses and keep the produce fresh for longer.

\n

Helping hand

\n

Yussuf, who is also the founder of Garissa Farmers Network Cooperative, termed it unfortunate that only 10 out of 150 farm groups practice green energy farming.

\n

"We have shown we can grow food here. What we need now is technical training, how to maintain larger systems, store power and maybe even sell surplus energy like the big plant does. The Chinese who built the Garissa station could help us take this to the next step," he said.

\n

For Abdul Latiff, despite his farm being just 4 km along the banks of the River Tana, he says he is unable to pump the water from the river to his adjacent 10-hectare piece of land.

\n

"It's painful to watch the river flow past while my crops wither," Latiff says. "Without affordable solar pumps or support to tap this water, the land will just remain a desert."

\n

Mohamed Sheikh Hassan, an agriculture officer of Garissa Township, said less than 5 percent of farmers in his county use solar despite the untapped solar bounty.

\n

"There is a huge potential for arid land farming along the areas like Fafi, Balambala, Garissa Township, Lagdera, Masalani and parts of Ijara," he said.

\n

The county has written proposals to international organizations such as the World Food Programme to strengthen their capacity and scale up the utilization of solar farming.

\n

"We are also exploring opportunities to work hand in hand with Chinese experts to expand solar farming in Garissa for our farmers to cut reliance on fossil fuels and fully harness this untapped resource," he said.

\n

The withdrawal of the Sustainable, Transformational and Accessible Water Interventions project, funded by the US Agency for International Development, caused a major setback for more than 200 beneficiaries before it could be completed, he said.

\n

To reduce postharvest losses, he said the completion of the Garissa Industrial Park will include cold storage facilities and is expected to enable local farmers to add value to crops such as tomatoes, lemons and rice.

\n

"This initiative seeks to transform Garissa's image from a climate-vulnerable county into a hub of innovation in arid land farming — demonstrating that even the desert can bloom," he said.

Displacement by AI worrying workers: Poll

\n

US people are deeply concerned over the prospect that advances in artificial intelligence could put swathes of the country out of work permanently, according to a new Reuters/Ipsos poll. The sixday poll, which concluded on Monday, showed 71 percent of respondents said they were concerned that AI will be "putting too many people out of work permanently". The new technology burst into the national conversation in late 2022 when OpenAI's ChatGPT chatbot launched and became the fastest-growing application of all time, with tech heavyweights like Facebook owner Meta Platforms, Google owner Alphabet and Microsoft offering their own AI products. Some 77 percent of respondents to the poll said they were worried the technology could be used to stir up political chaos, a sign of unease over the now-common use of AI technology to create realistic videos of imaginary events. More than half of US citizens, some 61 percent, said they were concerned about the amount of electricity needed to power the fast-growing technology.

Britain abandoned its demand that Apple provide so-called backdoor access to any encrypted user data stored in the cloud, US Director of National Intelligence Tulsi Gabbard said on Monday. Gabbard indicated London and Washington had resolved their high-stakes dispute over electronic privacy, writing on X that she and President Donald Trump and Vice-President JD Vance spent the "past few months" working with the UK government. The dispute surfaced at the start of the year with a news report that British security officials had issued the US tech giant with a secret order requiring the creation of backdoor access to view fully encrypted material. Apple challenged the order, which raised fears of electronic spying by national security officials.

\n

The Chinese yuan has strengthened steadily against the US dollar this year, with the offshore yuan gaining over 2 percent year-to-date.

\n

Economists attribute the increase to both external and domestic drivers. Globally, the US economy has been weighed down by high interest rates and trade policy uncertainties, weakening the dollar index. Meanwhile, domestically, China's resilient economic fundamentals, continued policy support, and more flexible exchange rate management have bolstered the renminbi.

\n

As of 4:30 pm on Tuesday, the offshore yuan, according to Wind Info, stood at 7.1857 per US dollar, up more than 2 percent since the start of the year.

\n

Wen Bin, chief economist at China Minsheng Bank, said, "Washington's new tax cuts and spending law, coupled with a downgrade of US sovereign credit rating, have heightened concerns over the sustainability of US fiscal policy, lending support to the yuan's appreciation against the dollar."

\n

At home, China has continued to roll out countercyclical, growth-stabilizing measures. With relatively steady economic data, advances in technological innovation and industrial upgrading, steps to curb "involution-style" competition that help stabilize prices, and recovering risk appetite in financial markets have all provided a firmer footing for the currency, Wen said.

\n

Duan Chao, chief macro analyst at Industrial Securities, said China's economy has shown notable resilience this year. Despite tariff-related headwinds from the United States, exports grew 7.2 percent year-on-year in the first half. He argued that China's commitment to high-quality development helps counter external uncertainties and contributes stability to global growth — a foundation for a stable yuan that is likely to persist.

\n

Duan added that China's economic resilience has kept the yuan steadier than the dollar, while policies introduced after US President Donald Trump's return to the White House have created major uncertainties, denting confidence in holding US assets over the long term.

\n

The US dollar closed the first half of 2025 with its steepest drop since 1973, as the dollar index, which measures the greenback against a basket of currencies of the US's key trading partners, slid about 11 percent during the first six months.

\n

While the currency rebounded 3.2 percent in July, recovering part of its losses, Morgan Stanley Research forecast further weakness, warning of an additional 10 percent decline by the end of 2026.

\n

The downturn was fueled by April's tariff announcements and the resulting policy and economic uncertainties, compounded by mounting concerns over growth, inflation and public debt.

\n

With the delayed effects of tariffs on growth and jobs, coupled with ongoing policy risks, downward pressure on the dollar is expected to persist. Foreign investors have also increased hedging on currency exposure to US assets, a move Morgan Stanley said will likely deepen the dollar's slide.

\n

In contrast, during this period, the steady performance of China's economy provided strong support for the yuan exchange rate. Accelerated cross-border capital inflows and increased holdings of yuan assets also boosted the currency, said Wang Youxin, a senior researcher at a research institute backed by Bank of China.

\n

China's central bank released its monetary policy implementation report for the second quarter of 2025 on Friday.

\n

The report reaffirmed the need to pursue a managed floating exchange rate regime based on market supply and demand with reference to a basket of currencies. It stressed upholding the decisive role of the market in the formation of the exchange rate, enhancing the resilience of the foreign exchange market, stabilizing expectations, firmly correcting pro-cyclical behavior, addressing any conduct that disrupts market order, and guarding against the risk of exchange rate overshooting, so as to keep the yuan exchange rate basically stable at an adaptive and equilibrium level.

\n

A research note from China Galaxy Securities pointed out that the central bank's remarks once again sent a policy signal of its commitment to maintaining basic stability in the currency market, helping guide market expectations and providing a proactive response to the potential rise in global financial market uncertainties.

\n

Chinese electronic games are continuously thriving in global markets, and are increasingly becoming carriers of culture to promote cross-cultural understanding and exchanges as a new universal language, said industry experts during the recent 22nd China Digital Entertainment Expo & Conference, better known as ChinaJoy, in Shanghai.

\n

By the end of June, China had a record 679 million gamers. In the first half, actual sales revenue of the domestic game market totaled 168 billion yuan ($23.3 billion), up 14.08 percent year-on-year, according to a report released on July 31 by Zhang Yijun, first vice-chairman of the China Audio-Video and Digital Publishing Association.

\n

Overseas sales of Chinese games exceeded $9.5 billion in the first half, growing 11.07 percent year-on-year. The United States, Japan and South Korea continued to be the main overseas markets for Chinese games, accounting for 55.63 percent of total sales. European nations such as Germany, the United Kingdom and France are becoming emerging destinations for more Chinese games, said the report.

\n

From a global perspective, China continued to hold the position as the world's largest game exporter in the first half, ranking first with a share of 32.6 percent of global total, according to a report released by mobile analytics firm AppsFlyer.

\n

Over the past five years, Chinese games have entered the markets of more than 100 countries and regions around the world. In particular, games such as Honor of Kings and Genshin Impact have accumulated hundreds of millions of users globally, said Ao Ran, executive vice-chairman of the China Audio-Video and Digital Publishing Association.

\n

"China's gaming industry has shown a positive trend toward high-quality and sustainable development in recent years, since a large number of Chinese enterprises are collaboratively creating world-class innovative video games within the global supply chain. Notably, the fine traditional Chinese culture is becoming the unique source of innovation and a differentiating advantage for Chinese games," said Richard Yu, vice-president and editor-in-chief at Tencent Interactive Entertainment Group.

\n

The hit title Black Myth: Wukong, an action role-playing video game rooted in Chinese mythology, is a prime example of the worldwide appeal of Chinese video games with a strong cultural identity. Industry experts agree that games are rapidly developing beyond products for entertainment, and becoming a new cultural form integrating with advanced technologies and an important carrier of Chinese cultural aspects that keep expanding globally.

\n

Yu pointed out that more Chinese game producers are ramping up efforts to make high-quality original games that draw both domestic and international players. Instead of simply putting cultural elements together, they explore deep into Chinese cultural connotations and strive to interpret them in innovative, globalized and modern ways.

\n

"As a composite cultural carrier that integrates various art forms such as literature, music, film and fine arts, games naturally possess the potential to promote cross-cultural understanding and boast the advantage of crossing cultural boundaries. Their interactivity turns the players into 'interpreters' of different cultures," Yu added.

\n

Not only Chinese producers, but also foreign companies are eyeing opportunities in the global collaboration and cultural integration with games as a bond. Representatives of over 200 companies from nations such as Japan, South Korea, the UK, France and Finland gathered for potential partnerships at the China International Game Developers Conference, which was held on July 31 as part of this year's ChinaJoy.

\n

"There were barely no really successful Chinese console and PC games 10 years ago, but recently we have seen game studios and producers instilling Chinese culture to create something different. China has a wonderful historical culture and that's part of the creativity. In France, we are very much into culture in general, and Chinese culture is no exception — it is something that resonates a lot with us," said Yves Blehaut, senior vice-president of strategic partnerships at Microids, a French video game publisher and developer.

\n

Sony Interactive Entertainment (Shanghai) Ltd and its PlayStation gaming platform are also actively looking to contribute to China's console game ecosystems. Following the success of Black Myth: Wukong on its platform, the company is expecting to cultivate more local game developers in China and better connect the nation's gaming industry and culture with the world. In 2016, the company established the "China Hero Project" to support Chinese console game developers, connect with global counterparts, and help them grow globally with games featuring Chinese culture.

\n

"China has the world's most game users and is one of the most critical and potential markets for PlayStation. We have noticed very early the potential and passion of Chinese game developers. Collaborating with over 400 Chinese game developers and publishers, we aim to introduce good Chinese games to the world," said Tatsuo Eguchi, chairman and president of Sony Interactive Entertainment, at the conference.

\n

To better navigate Chinese game developers in overseas markets, the Research and Service Center for Game Globalization was inaugurated in Shanghai at the conference. It aims to provide one-stop services such as overseas market analysis, compliance guidance, financial services, legal protection and copyright protection.

\n

Moreover, a first batch of guidelines targeting the Japanese, South Korean, British and French markets were also released at the event to support Chinese games' global expansion, comprehensively covering sectors including policies, regulations, market environment, culture, customs and user preferences. More guidelines on other countries in regions such as North America, Europe, Southeast Asia and the Middle East will also be released this and next year.

\n

"The globalization of games ultimately involves a two-way cultural exchange. Games themselves are self-contained digital worlds where different cultures meet and spark inspiration. So while publishing Chinese games overseas, we also help introduce global cultures into China," said Yu of Tencent Interactive Entertainment.

\n

"We obviously see more foreign friends and international participation at ChinaJoy this year. With games building a globalized platform, we expect to enhance exchanges, reduce barriers and accelerate integration, which will carry us all farther," he added.

\n

Running from Aug 1 to 4, this year's ChinaJoy attracted over 790 business exhibitors from 37 countries and regions including the US, Canada, UK, Germany, Japan and South Korea.

Jayden Daniels (left) of the Washington Commanders talks with Joe Burrow of the Cincinnati Bengals after an NFL preseason game at Northwest Stadium on Monday in Landover, Maryland.

\n

LANDOVER, Maryland — In a matchup of LSU Heisman Trophy-winning quarterbacks, Jayden Daniels rushed for a 14-yard touchdown in his lone possession, while Joe Burrow directed two touchdown drives in the Cincinnati Bengals'31-17 win over the Washington Commanders on Monday night.

\n

Burrow played three possessions, completing nine of 14 passes for 62 yards. The 2020 Heisman winner found wide receiver Charlie Jones for a four-yard touchdown reception on his final toss. Running back Chase Brown's one-yard touchdown on fourth-and-goal capped a 58-yard drive on the opening possession at Northwest Stadium.

\n

The Bengals (1-1) planned on using their starters longer in preseason games to hopefully avoid a string of poor regular-season starts. Over the two games with Burrow playing at quarterback, Cincinnati has scored touchdowns on four of five possessions.

\n

"Those are just incredibly valuable reps. Usually, you work out those kinks in the first couple of weeks in the regular season, and we've worked them out the last two weeks," Burrow said.

\n

Head coach Zac Taylor had his share of nitpicks, as all coaches do, but said he likes "where this offense and this team is at right now, at this point".

\n

In Daniels' likely only preseason appearance, Washington (0-2) drove 74 yards on four plays to tie the score 7-7. Following runs of 19 and 40 yards by Deebo Samuel and Chris Rodriguez, respectively, Daniels evaded pass rushers and suspect tackling for a 14-yard dash up the middle. The reigning Offensive Rookie of the Year and 2023 Heisman recipient did not attempt a pass, nor a slide on the touchdown despite running into traffic.

\n

"I'm playing football. I know everybody puts an emphasis on the preseason, but it's a game to me," Daniels said.

\n

Washington head coach Dan Quinn would prefer his star quarterback to, at times, choose caution in those spots, "but it is part of his game. It's what makes him a special player".

\n

Considering the Commanders played without three offensive line starters, two starting receivers, and tight end Zach Ertz, limiting Daniels' exposure to hits and a slick field courtesy of pregame rain was probably the proper call. Terry McLaurin, a 2024 second-team All-Pro wide receiver, remains a non-participant amid a contract dispute.

\n

Rookie running back Jacory Croskey-Merritt raced for a 27-yard touchdown on Washington's second possession and finished with 46 yards on 11 carries. The seventh-round pick became a training camp sensation for the Commanders, and his scoring scamper won't dampen any enthusiasm. Rodriguez increased his chances for a rotation spot by rushing for a team-high 62 yards on six carries.

\n

Matt Gay's 27-yard field goal accounted for Washington's second-half scoring. Cincinnati kicker Evan McPherson drilled a 54-yard field goal with 3:06 remaining.

\n

Receiving notice

\n

Bengals roster hopeful Mitchell Tinsley made two impressive touchdown catches — both from quarterback Jake Browning — in a span of 20 seconds late in the first half. Following linebacker Barrett Carter's interception, the wide receiver's leaping, toe-tapping reception with 14 seconds remaining gave Cincinnati a 28-14 halftime lead.

\n

Robinson removed

\n

Commanders RB Brian Robinson did not dress for Monday's game, nor was he at Northwest Stadium amid recent reports of Washington seeking to trade the four-year veteran. Quinn said that he and general manager Adam Peters informed Robinson of their decision to sit him out on Sunday afternoon. Quinn declined to share Robinson's reaction. "News like that is not always that easy," the coach said.

\n

Robinson rushed for 799 yards and eight touchdowns last season, but the emergence of Croskey-Merritt has the Commanders reconsidering their backfield options.

There has been significant improvement in the scores of Chinese taking the Test of English as a Foreign Language and the International English Language Testing System exam over the past decade, a trend experts said reflected genuine advances in overall English proficiency, though persistent challenges remain.

\n

According to Omar Chihane, general manager at TOEFL, the average TOEFL score of Chinese students rose from 80 to 86 over the past decade, with reading scores consistently exceeding the global average since 2008.

\n

From 2008 to 2023, the gap between Chinese test-takers' TOEFL writing scores and the global average continued to narrow. In 2023, the average scores for speaking and writing among Chinese examinees were only 0.2 point and 0.1 point below the global average, respectively, he said.

\n

According to the British Council, one of the major administrators of IELTS, the overall average score of Chinese academic IELTS examinees reached 5.9 during 2023-24, a 0.2-point increase compared with 2018-19. Writing scores surged most notably by 0.4 point, while historically weak speaking skills improved by 0.2 point. Nearly 60 percent of candidates scored 6.0 or higher during 2023-24 — a 12 percent jump from five years earlier.

\n

Lan Xi, director of studies at New Channel International Education Group, a Beijing-based overseas study consultancy, said the English test scores reflect significant improvement in the actual English language proficiency of Chinese students.

\n

"The narrowing score gaps in speaking and writing are the result of moving away from rote test-taking techniques toward holistic language proficiency development," Lan said.

\n

Digital learning resources have significantly lowered access thresholds to quality materials, while teaching frameworks now prioritize critical thinking over knowledge transfer, he added.

\n

Student motivation for English learning has evolved from achieving target scores to meeting the practical demands of future overseas study or global workplaces. This has resulted in more proactive engagement in holistic training in all language skills, he said.

\n

Lan highlighted several concrete improvements: Students now construct thesis-driven arguments in their academic writing instead of relying on templates, analyze authors' evidence during critical reading rather than translating texts word-by-word, and actively engage in classroom debates instead of giving passive responses.

\n

Shen Zhourong, a teacher at Beijing International Studies University's School of Interpreting and Translation, said that vocabulary expansion has boosted students' foreign journal reading abilities.

\n

In output skills, classroom debates and daily expression show upward trends. However, academic writing continues to be a challenge, Shen said.

\n

He noted that even native Chinese speakers need continuous refinement in Chinese academic writing, adding that English academic writing demands greater logical coherence and lexical precision, leaving many students struggling despite strong speaking competence.

\n

Wu Peng, dean of the Overseas Education College at Jiangsu University, noted a similar trend. While pointing out "modest upward trends" in domestic English proficiency test scores, he cautioned that high scores do not necessarily reflect commensurate improvement in practical language skills.

\n

To address English speaking and writing deficiencies among students, the school has introduced more practical learning tools, such as English debate competitions and drama performances. It has also incorporated digital resources to provide personalized learning, real-time feedback and one-on-one tutoring.

\n

Both experts confirmed the persistent score-application gap. Shen attributed this to the structural nature of standardized tests, which allow targeted preparation that boosts scores without necessarily improving practical language ability.

\n

Wu of Jiangsu University said that exam-oriented traditions prioritize scores over communication skills. Students lack authentic practice opportunities and fear making mistakes due to cultural factors favoring passive learning.

\n

Nevertheless, the phenomenon of "mute English" — students mastering grammar and vocabulary but struggling to speak — is showing signs of easing.

\n

Shen of BISU attributed the progress to three factors: China's growing international engagement, early exposure to English education and increasing parental emphasis on language learning. Wu pointed to study-abroad programs, international student exchanges and digital platforms facilitating global communication.

\n

Wu emphasized that sustaining this improvement requires a fundamental mindset shift: Students should view English as a communication tool rather than merely a test subject. Such a shift is critical for China's deepening global integration, he said.

Scientists at Tianjin University have developed a high-energy lithium metal battery with an energy density two to three times greater than that of existing lithium-ion batteries, according to findings published in the journal Nature recently.

\n

The breakthrough was achieved by redesigning the battery's electrolyte to improve the movement of lithium ions. With batteries of the same weight, the range of electric vehicles is expected to multiply.

\n

The findings are a significant step in meeting the urgent demand in fields such as electric transportation and the low-altitude economy for high-energy, long-duration rechargeable batteries.

\n

Energy density, the amount of energy that can be stored per mass, is a core performance indicator for batteries.

\n

"For a long time, scientists have hoped to increase the energy density of batteries while ensuring maximum safety, enabling batteries to store more electricity with lighter weight and smaller volume," said Hu Wenbin, a professor at the School of Materials Science and Engineering at Tianjin University and leader of the research team.

\n

Developers have faced challenges in improving the performance of traditional lithium batteries, Hu said. The electrolyte of traditional lithium batteries is generally composed of a single salt and a few solvents, forming a point-like structure. That structure limits the migration capability of lithium ions, resulting in imbalances in the electrolyte and restricting the battery's energy storage and cycling performance.

\n

To address the problem, the team designed an ultra-dispersed electrolyte, or UDE, after years of research.

\n

"Compared with the relatively single composition of traditional electrolytes, this electrolyte integrates multiple solvents and salts, significantly enhancing the disordered solvation micro-environment. It creates a face-like microscopic environment, effectively reducing the kinetic barriers to lithium-ion movement," Hu said.

\n

The new electrolyte design optimizes performance and achieves internationally recognized high energy density targets, Hu added. Pouch cell energy density exceeds 600 watt-hours-per-kilogram, and battery pack energy density exceeds 480 Wh/kg.

\n

By comparison, United States electric car manufacturer Tesla's 4680 battery has an energy density of about 300 Wh/kg, and Chinese electric vehicle company BYD's Blade Battery is around 150 Wh/kg.

\n

"This lays an important foundation for the future application of lithium metal batteries," Hu said.

\n

The team also discovered that within the dispersed microscopic environment formed by the UDE, a solid electrolyte interphase, or SEI, develops inside the battery.

\n

"This robust and stable interface enables the electrode to remain stable during prolonged cycling, which is crucial for enhancing the lifespan of high-performance lithium metal batteries," Hu said.

\n

The researchers used artificial intelligence to screen electrolyte materials, significantly shortening development time. They collaborated with the National University of Singapore and several Chinese companies.

\n

With support from national-level platforms such as Tianjin University's National Industry-Education Platform of Energy Storage and the National Key Laboratory of Precious Metal Functional Materials, the team is promoting commercialization and practical application of the findings.

\n

A pilot production line for high-energy lithium metal batteries is operational, and the technology has been tested in three models of domestically developed micro electric drones. Their flight endurance increased by up to 2.8 times compared with current battery systems.

The Tien Kung Ultra robot (third from left), developed by a Beijing-based company, claims 100m gold at the 2025 World Humanoid Robot Games in Beijing on Sunday, finishing in 21.5 seconds.

\n

The inaugural World Humanoid Robot Games in Beijing have showcased how sport is accelerating robotics innovation and capturing public imagination.

\n

Over three days, more than 500 robots from 280 teams across 16 countries competed in 487 events that ranged from athletics and soccer to combat and hotel service simulations.

\n

At the closing ceremony on Sunday, organizers announced the establishment of the World Humanoid Robotics Games Federation, dedicated to advancing humanoid robot sports, with Beijing set to host the second Games in August 2026.

\n

Spectators were left astonished as humanoid robots sprinted 1,500 meters at speeds rivaling university athletes or performed synchronized dances dressed as Terracotta Warriors. Some robots veered off track or collided with referees, drawing laughter and applause, while others passed soccer balls flawlessly, occasionally scoring in their own goals. The mix of impressive feats and endearing mishaps underscored both the rapid progress and the challenges that remain in better managing humanoid mobility and coordination.

\n

"These Games bring together top-tier teams from across China and around the world, providing a platform to showcase their latest research and achievements in robotics, and it also fosters mutual learning and collaboration among participants," said Lou Kaiqi, who directed a Terracotta Warrior-themed dance performance.

\n

His team developed group-control software to synchronize nine robots in complex routines.

\n

"Each unit was precisely calibrated to move in rhythm, creating a visually striking performance," he added.

\n

The growing publicity around such events has drawn broader attention to the robotics industry, particularly to advancements in robotic movement. This has significantly accelerated technological progress in the field over the past two years, driving remarkable developments in robotic capabilities.

\n

"This event's greatest value lies in public engagement," said Huang Siyuan of the BIGAI-Unitree team, which competed in the hotel service challenge. "People can see how autonomously and efficiently these robots handle everyday tasks, something many care about."

\n

The Games are also accelerating technical breakthroughs by taking humanoid robots out of laboratories and into real-world scenarios. The competition acts as a testing ground, helping refine viable innovations and push them toward wider adoption. Huang said humanoid robots hold significant potential to revolutionize hotel cleaning operations.

\n

"The benefit of humanoid robots is safety and privacy. Many people worry about inconsistent cleaning quality in hotels, but robots can perform tasks with higher reliability and precision, ensuring greater trust. Their standardized execution reduces human error, making them a preferable solution for some environments," Huang said.

\n

Huang added that hotel service robots need to perform autonomous navigation and interactive operations within the environment, such as picking up a suitcase or collecting trash and disposing of it in a bin. These actions demonstrate humanoid robots' strong interactive capabilities in real-world scenarios.

\n

The Games also highlighted Beijing's ambitions to become a global robotics hub. The city has rolled out multibillion-yuan investment funds, innovation centers and industrial policies to support humanoid robot research, manufacturing and deployment. Its humanoid robot sector now accounts for about a third of China's market, with revenues up nearly 40 percent in the first half of this year, according to data released by authorities.

The US State Department issued its annual human rights report on China on Tuesday last week, in which it once again groundlessly pointed an accusing finger at the country for alleged human rights abuses.

\n

The report is divorced from reality and constitutes a grave interference in China's internal affairs. The US' double standards on human rights issues and its intention of weaponizing human rights for its own geopolitical interests are plain to see.

\n

China's human rights achievements are widely recognized around the world. The country's development is about providing a better life for the 1.4 billion Chinese people and the country follows a people-centered development approach. It has charted a path of human rights development that suits China's national conditions. The path has been embraced by the people and conforms to the trends of the time.

\n

In the Xinjiang Uygur autonomous region, people of different ethnic groups enjoy their rights according to law. The region has achieved noticeable results in advancing socioeconomic development and human rights, and it remains stable and tranquil. As a result, it has been able to open its doors wider to the outside world, receiving more than 200 million domestic and foreign tourists annually. It has also become a major hub of the Belt and Road Initiative and a major channel for the China-Europe Railway Express.

\n

Likewise, human rights in the Xizang autonomous region and its development have made evident progress. The success of the Hong Kong Special Administrative Region in practicing "one country, two systems" is also there for everyone to see.

\n

While China is willing to engage in dialogue and exchanges on human rights with all countries, it will never allow any country to interfere in its internal affairs, jeopardize China's interests, or tarnish China's image under the pretext of "human rights". The nation is firmly opposed to the politicization and weaponization of human rights issues, and the arbitrary use of human rights by some developed countries to suppress developing countries that pursue independent and autonomous policies.

\n

Before lecturing other countries on human rights, the US should face squarely its own human rights issues. The State Council Information Office of China on Sunday released a report on human rights violations in the US in 2024, indicating how grave the human rights conditions are in the country.

\n

The inequality in US society continues to increase, with the rich getting richer and the poor getting poorer. As a result the US public is deeply disillusioned with the country's democratic system in which money dictates policy. For instance, the root cause of the US' opioid crisis lies in interest hijacking, government-business collusion and regulatory failure. Interest groups, driven by profit, have intensified their lobbying efforts and deceptively promoted the use of opioids. The number of fatal overdoses involving synthetic opioids and stimulants has surged in the past few years.

\n

Gun violence remains rampant in the US. According to the Sunday report, there were 503 mass shootings and 45 school shootings in the US in 2024. In all, 40,000 Americans were killed by gun violence last year, including over 1,400 children. Meanwhile, police brutality — particularly against non-white ethnic minorities — persists in total disregard of human rights. African Americans, for instance, are three times more likely to be shot and killed by police than white Americans.

\n

Worse, the human rights issues the US creates are not just restricted to its own territory.

\n

While hyping up fabricated violations of the "human rights" of Uygurs and other ethnic minorities in China, particularly Muslim groups, the US administration pays no heed to the ugly role it is playing, both directly and indirectly, in the worsening humanitarian crisis in Gaza.

\n

The US is also the world's biggest user of unilateral sanctions. It has increasingly imposed them on some less-developed countries in recent years. More than 60 percent of low-income countries are now under some form of financial penalty imposed by the US, according to the report.

\n

Under the collusion of power and capital, human rights have been distorted into mere props in a political "show" and bargaining chips in a power "casino", completely deviating from their core values and fundamental principles. As the report says, the tumultuous political stage of the US in 2024 acts as a prism, reflecting the structural dilemmas of US-style human rights.
