鱼不能没有水我不能没有你
[yú bù néng méi yŏu shuĭ wŏ bù néng méi yŏu nĭ]
This is a metaphorical declaration of love or dependency on someone else. Fish cannot live without water – similarly, this person feels they cannot live without another particular person; it symbolizes how crucial and inseparable this bond or connection with the individual is.
