面子 — the concept of face

面子 (miànzi) is social face — reputation, dignity, and standing in the eyes of others — and it sits near the center of nearly every Chinese social interaction. 'Giving face' (给面子) means actions that publicly honor or defer to someone: praising them in front of others, accepting their invitation, letting them win a minor point. 'Losing face' (丢脸) is the opposite, and it's most damaging when it happens publicly.

In practice, this means critical feedback is normally given privately, not in front of a group; direct public criticism of a colleague, student, or family member is avoided even when it's factually justified, because the public setting is what causes the real damage. Refusing an invitation or a gift outright, without a face-saving excuse, can cause the other person to lose face just from being refused.

Face-giving works both ways and builds real social credit (人情): helping someone look good in front of their boss or family is a favor that's expected to be reciprocated later, and accepting a small favor or invitation is itself a way of giving face back to the person offering it. 死要面子 ('would rather die than lose face') describes someone who takes this to an unhealthy extreme, spending beyond their means or refusing help just to maintain appearances — a recognized cautionary idea within the culture itself, not just an outsider's critique.
