12 Essential Chinese Idioms for HSK 4 Learners

Foresee big from small signs

Literal: See small know large

The Han Feizi observes that the sage sees (见) the minute (微) and thereby knows what is sprouting, sees the beginning and thereby knows the end — to catch the small sign is to know (知) the large development (著) it precedes. The skill named is not prediction but attention: the evidence was there the w...

Trace back to source

Literal: Chase root trace source

To chase (追) the root (本) and trace (溯) the source (源). Both halves are the same instruction in different terrain, one botanical and one riverine, and 溯 specifically means moving against the current — the work is upstream and harder than going with it. That is the sense the phrase carries: not merel...

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).

Find value among worthless

Literal: Sift sand pick gold

The Grades of the Poets quotes Xie Hun comparing two writers: Pan Yue's verse is brilliant as unrolled brocade, fine everywhere, while Lu Ji's is like parting (披) the sand (沙) to pick out (拣) gold (金) — treasure turns up, and you go through a great deal to reach it. Liu Zhiji later used the four-cha...

Have great vision

Literal: Hills and valleys in heart

Hills (丘) and ravines (壑) already inside the chest (胸有). The phrase belongs to landscape painting, where the whole terrain was expected to exist in the painter's mind before the brush touched the silk — the same claim 胸有成竹 makes about a stalk of bamboo, and the two are near neighbours. What distingu...

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...

Plan strategy carefully

Literal: Work the counting rods in the command tent

Liu Bang, asked why he had won the empire when Xiang Yu was the better soldier, named three men he could not equal. Of Zhang Liang he said: 运筹帷幄之中，决胜千里之外 — turning the counting rods inside the tent curtains (帷幄), he decides victory a thousand li away. The Records of the Grand Historian keeps the spe...

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...

Hide malice behind smile

Literal: Hide knife in smile

This descends from accounts of Li Yifu, a chancellor under the Tang, who was mild in manner and unfailingly courteous, and who destroyed anyone who crossed him. Contemporaries said he carried a knife (刀) hidden (藏) inside (里) his smile (笑). It is also the tenth of the Thirty-Six Stratagems. The smil...

Overcome all obstacles

Literal: Cut thorns break brambles

The History of the Later Han records Emperor Guangwu presenting Feng Yi to his court as the man who had been his registrar when he first raised troops: 为吾披荆棘，定关中 — he cut through the thorns for me and settled the land within the passes. The four-character idiom grew out of that sentence, adding 斩, t...

Study extremely hard

Literal: Hang beam stab thigh

Two men, two methods. Sun Jing, of the Han, tied his hair to the roof beam (悬梁) so that nodding off would pull him upright. Su Qin, generations earlier, had been sent home from Qin in disgrace after ten memorials went unread, and read through the night with an awl beside him, stabbing (刺) his own th...

Study despite poverty

Literal: Pierce wall steal light

Kuang Heng's family could not afford lamp oil, so he bored (凿) a hole in the party wall (壁) and stole (偷) the light (光) that came through from the neighbour's side. The account is in the Miscellany of the Western Capital, which adds that he hired himself out to a rich household and asked to be paid ...
