你是谁的谁为誰掉眼泪
[nĭ shì shéi de shéi wéi shuí diào yăn lèi]
Expressing the confusion and emotion when someone is entangled in complex interpersonal relationships: whose who, and for whom one weeps? It conveys an emotionally tangled sentiment, suggesting being lost among the roles of love, friendship, and strangers, with unknown affectionate confusions.
