忘了水的鱼还会不会哭
[wàng le shuĭ de yú hái huì bù huì kū]
The title translates to 'will a fish that forgot water still cry?' It's metaphorical for a situation where a person might feel lost and out of place in their familiar environment. The expression evokes sadness and confusion about adapting after forgetting or losing one's roots.
