君子有诸己而后求诸人，无诸己而后非诸人。
释义Explanation
这句话的意思是：君子先让自己具备某种品德，然后才会要求别人具备；先让自己没有某种缺点，然后才会批评别人。它强调以身作则和推己及人的恕道精神，认为只有自己做到了，才有资格要求他人。在现代，领导者、教师、家长都需先正自身，才能让人信服。
This saying underscores the Confucian principle of leading by example. A junzi (gentleman) first cultivates the virtues he expects in others and eliminates his own flaws before criticizing others. It reflects the "shu" (reciprocity) ethic: do not demand of others what you cannot do yourself. The message is that authority and moral influence derive from personal integrity and self-discipline, not from mere words or status.
使用场景Usage
在职场中，管理者要求团队遵守规章，自己却迟到早退，团队自然不服。这句提醒领导者，应先做到再要求别人。教育子女时，家长要孩子少玩手机，自己却沉迷屏幕，效果也差。以身作则是建立信任和威信的根本。
In the workplace, a manager who demands punctuality and hard work while being frequently late loses credibility. This quote reminds leaders to model the behavior they expect. Similarly, parents who tell children to limit screen time while constantly scrolling themselves undermine their own message. Leading by example builds trust and authority far more effectively than words alone.
