鱼无泪鱼眼泪
[yú wú lèi yú yăn lèi]
"Fish Without Tears" or "Fish and Its Tears" is somewhat poetic. Generally, fish can't shed tears due to biological reasons but this implies the owner's heartache or sorrow so profound, they are like fish unable to weep. In Chinese culture, sometimes 'Fish Eyes' also symbolizes longing or helplessness.
