'Zhèng biǎoxiàn' literally combines 'zhèng' (to strive, to earn) with 'biǎoxiàn' (performance, behavior, or demonstration). It describes the act of deliberately trying hard — often in an exaggerated, insincere, or overly eager way — to impress authority figures like teachers, bosses, or parents. The connotation is usually negative: it suggests showing off, seeking approval through superficial effort rather than genuine contribution or competence.

This phrase is common in social and workplace contexts where hierarchy matters. It implies a lack of authenticity — for example, volunteering for every task before a supervisor, speaking up excessively in meetings just to be noticed, or over-praising someone publicly. While the characters individually are neutral, the compound carries strong pragmatic weight: it’s used to critique performative behavior, not sincere diligence. Native speakers often use it with mild disapproval or gentle teasing, especially when describing children or junior colleagues.
