凫胫虽短，续之则忧；鹤胫虽长，断之则悲。
释义Explanation
这句话以凫（野鸭）腿短、鹤腿长的自然之态为例，强调万物各有其天然本性。强行续短或断长，都违背自然，只会导致痛苦。庄子借喻阐明，人为干涉、削足适履往往适得其反，尊重天性与差异方为智慧，引导人们放下偏执的标准，接纳各自本然的存在状态。
This saying uses the natural shortness of a duck's legs and the length of a crane's legs to illustrate that every being has its inborn nature. Forcibly lengthening the short or shortening the long violates nature and only causes distress. Zhuangzi suggests that artificial interference often backfires; true wisdom lies in respecting innate differences and letting things be as they naturally are.
使用场景Usage
在教育中，一味要求所有孩子在同一个标准下竞争，就如同续凫断鹤，忽视个体天赋差异，易使孩子丧失自信与热情。在管理上，若强行将不同性格的员工塞进统一模板，也会扼杀创造力。这句话提醒我们因材施教、量才适用，顺应而非扭曲本性。
In education, forcing every child to compete under identical standards is like lengthening a duck's legs or shortening a crane's—it ignores natural talents and may crush confidence. In management, squeezing diverse personalities into a uniform mold stifles creativity. This proverb urges us to adapt methods to individuals, honoring innate dispositions rather than distorting them.
