君子不失足于人，不失色于人，不失口于人。
释义Explanation
此句强调君子在与人交往时，从举止、神色到言语都应保持得体与庄重，不可因情绪或场合而失态。'失足'并非摔倒，而是行为越轨；'失色'指表情管理失控；'失口'则是言语轻率。三者层层递进，说明外在礼仪根植于内在修养。现代人可借此提醒自己在社交中既尊重他人，也守护自身形象。
This sentence stresses that a noble person maintains proper bearing, composed expression, and careful speech in all interactions. 'Losing one's footing' figuratively means improper behavior; 'losing countenance' suggests emotional loss of composure; 'losing one's mouth' means speaking thoughtlessly. These three aspects progress from action to expression to word, showing that outward propriety stems from inner cultivation. It reminds modern people to respect others and protect their own integrity in social settings.
使用场景Usage

In modern workplaces, social gatherings, or online communication, this maxim reminds us to maintain composure.
