10 Chinese Idioms With Mouth (口/嘴)

Repeated by enough people, a falsehood passes for truth

Literal: Many mouths melt gold

This is from the Discourses of the States, paired there with another line: many hearts make a city wall, and many mouths (众口) melt (铄) metal (金). Gold does not melt from talk, which is the point — enough voices saying the same thing achieve what should be impossible. The original is a warning about ...

Hide evil behind sweet words

Literal: Mouth honey belly sword

Li Linfu ran the Tang court for nineteen years by agreeing warmly with everyone and destroying them afterwards. The Comprehensive Mirror records the verdict of his contemporaries: Li Linfu has honey (蜜) in his mouth (口) and a sword (剑) in his belly (腹). The organs are not decorative — Chinese physio...

Read between lines

Literal: Watch words observe face

This psychological idiom combines watching words (察言) and observing expressions (观色), reflecting ancient Chinese diplomatic practices where court officials needed acute skills in reading both verbal and non-verbal cues. The practice became crucial during the Warring States period, where misreading a...

Live as a recluse in the wild

Literal: Pillow stream rinse stone

Sun Chu, meaning to say he would pillow on stones and rinse in the stream (枕石漱流) — the standard image of the recluse — got it out backwards as pillowing on the stream (枕流) and rinsing with stones (漱石). Asked by Wang Ji how a stream could be a pillow or a stone a mouthwash, he answered without pausin...

Speak without meaning it

Literal: Words not from heart

The Zuo Zhuan observes that where trust does not come from within — 信不由中 — pledges are worthless however elaborately they are dressed up. Words (言) that do not proceed (不由) from what is inside (衷) may be perfectly courteous and still mean nothing at all. The phrase is about the gap between what is s...

All talk no substance

Literal: Talk big and empty

To boast and boast (夸夸) in one's (其) talk (谈). The doubling is what carries the judgement — a single 夸 is simply to praise or to exaggerate, and repeating it turns the exaggeration into a manner rather than an occasion. The phrase says nothing about whether the claims are false, only that the speaki...

Penetrating deeply to the essence

Literal: Whip strikes into core

This descends from Cheng Hao of the Song, whose 鞭辟近里 urges driving study inward toward what is essential rather than accumulating surfaces. The image is of a whip (鞭) driving (辟) something in (入) to the interior (里), and the violence in it is deliberate: getting to the centre of a matter takes force...

Exhausted from excessive talking

Literal: Mouth dry tongue parched

Mouth (口) dry (干) and tongue (舌) parched (燥). The phrase is physical before it is figurative and describes the specific state produced by talking for a long time without drinking. Its normal use is as a complaint about wasted effort: 说得口干舌燥, to have talked oneself hoarse — with the implication, near...

Broadly satisfactory, better than feared

Literal: Somewhat rouses one's spirits

Emperor Guangwu, told that his general Wu Han was still ordering his troops while everyone else was dispirited, said 吴公差强人意 — Wu rather rouses one's spirits. 差 there means somewhat and 强 means to hearten, so the original is a compliment. The modern reading takes 差 as poor and produces the opposite s...

To sum up everything discussed

Literal: Summed up and put in words

Summing up (总) and thereby (而) putting it into words (言之). Unlike most of its neighbours this has no image in it at all — it is a piece of classical connective tissue that hardened into a set phrase, and its whole job is to signal that what follows is the conclusion. That makes it genuinely useful t...
