原浊者流不清，行不信者名必耗。
释义Explanation
源头混浊，水流就不会清澈；行为不守信用，名声必定受到损耗。墨子以此比喻内在品性对外在声誉的决定作用，强调诚信是立身之本。如果一个人做事不讲信用，即便暂时获得名声，最终也会因失信而名誉扫地。这句话提醒我们，要想拥有良好声誉，必须从自身行为做起，保持诚实守信。
This saying uses the metaphor of a muddy source producing an unclear stream to illustrate that dishonest conduct inevitably damages one's reputation. Mozi emphasizes that inner integrity is the foundation of external trust. Even if someone gains temporary fame through deceit, that fame will eventually collapse because of broken promises. Therefore, to build a lasting good name, one must act with honesty and consistency. The message is that reputation is not built by words or appearances but by the steady practice of trustworthiness in daily life.
