10 Respectful Chinese Idioms for Teachers' Day (教师节)

Integrate many strands into one understanding

Literal: Merge and flow through completely

Zhu Xi gave the phrase its lasting sense in the collected works, describing the point a student reaches after long effort and thorough investigation, when the separate things learned melt together (融会) and run right through (贯通) one another — raise one corner and get three back, hear one thing and k...

Learning is limitless

Literal: Ocean of learning has no shores

This is from the second half of a well-known couplet, 书山有路勤为径，学海无涯苦作舟 — the mountain of books has a path, and diligence is that path; the sea (海) of learning (学) has no shore (无涯), and hard work is the boat. It is popularly attributed to the Tang essayist Han Yu, though the attribution is traditiona...

Learn many from one example

Literal: Raise one reflect three

Confucius, in the Analects, said he did not go on teaching a man who, shown one corner, could not come back (反) with the other three (三) — 举一隅不以三隅反，则不复也. The image is a square: you are given one corner and expected to supply the rest. It is a statement about what a teacher owes and what a student mu...

Learn new through studying old

Literal: Review old know new

Confucius, in the Analects: 温故而知新，可以为师矣 — one who warms (温) the old (故) and thereby knows (知) the new (新) is fit to be a teacher. 温 is the word for reheating food, so the image is of returning to what you already have rather than acquiring more. The claim is specific and quite demanding: review alon...

Student surpasses master

Literal: Blue comes from indigo plant

Xunzi opens his chapter on learning with it: 青，取之于蓝，而青于蓝 — blue (青) is taken from (出于) the indigo plant (蓝), and is bluer than the plant. The point is the student's, not the teacher's: nothing is being criticised, and the dye is better precisely because the plant existed. Common speech runs it as 青出...

Gentle, nurturing influence

Literal: Spring wind and nurturing rain

This is from the Mencius, which counts among a teacher's modes the one who transforms a student as a timely rain does — the spring wind (春风) and the rain that transforms (化雨). Nothing is forced; the growth is the student's own, and the teacher supplies the conditions. It is reserved for education ra...

Give out until nothing is left

Literal: Spring silkworm until death

This image comes from Li Shangyin's Untitled poem of the Tang dynasty: 春蚕到死丝方尽，蜡炬成灰泪始干 — the spring (春) silkworm (蚕) spins until death (死) before its thread is done, and the candle's tears dry only when it has burned to ash. The couplet is a love poem, and the silkworm is a figure for longing that d...

Humbly seek guidance

Literal: Move wine jar seek teaching

Moving (移) one's own wine cup (樽) across to where somebody is sitting, in order to receive (就) instruction (教). The gesture is the entire meaning: the person who wants to learn crosses the room, instead of summoning the teacher or waiting to be approached. Late imperial vernacular writing uses it of...

Learn from the worthy

Literal: See worthy wish equal

Confucius in the Analects: seeing (见) a worthy man (贤), think of (思) matching him (齐) — and seeing an unworthy one, turn inward and examine yourself. The second clause is normally left off and is the sharper half, since it makes every encounter instructive regardless of who you meet. What the phrase...

Constantly improve

Literal: Perfect seek more perfect

This descends from Zhu Xi's commentary on a line in the Analects about cutting and polishing: what has already been worked finely (精) should be worked finer still — 治之已精，益求其精. The phrase assumes the work is already good, which is what distinguishes it from ordinary diligence; the refinement it deman...
