猫尾不让鱼生
[māo wĕi bù ràng yú shēng]
Literal translation: 'Cat’s tail refuses the life of fish.' This may mean a cat is too proud and won’t settle for an undesired choice (living as a fish). Metaphorically, it reflects a strong will, not willing to compromise, possibly referring to someone with a clear personal standard who prefers their own path in life.
