鱼亡海哭
[yú wáng hăi kū]
The phrase 'fish dies, the sea cries' expresses an exaggerated form of despair. The idea that if a fish (possibly representing a person or part of one's self) dies, then even the sea, something vast and enduring, will grieve. It signifies a deep level of sorrow or distress beyond what might normally be expected.
