亡鱼是深海的旧疤浮云是天空的旧伤
[wáng yú shì shēn hăi de jiù bā fú yún shì tiān kōng de jiù shāng]
This name compares a lost fish as an old scar in the deep sea, and fleeting clouds as an old injury in the sky. It reflects melancholic emotions and memories which are painful yet inevitable parts of life, suggesting the speaker may be someone who harbors pain or loss but continues to exist alongside these feelings.
