亡鱼是深海的旧痕
[wáng yú shì shēn hăi de jiù hén]
'Wangyu shi shenhai de jiu hen', translated as 'Lost Fish is an Old Scar of the Deep Sea', expresses the pain from past events that may feel far off but have profound impacts on oneself; 'Lost fish' metaphorically refers to something precious but irrecoverable. The deep sea suggests where the pain has been submerged deep within.
