放开拥抱就各奔一方
[fàng kāi yōng bào jiù gè bēn yī fāng]
It conveys that once we let go of each other after the embrace, everyone has to walk their own separate path. This reflects a sense of helplessness faced by two people in front of reality. Sometimes despite the strong emotional bond between them, factors like distance can drive them apart. So it carries a feeling of sadness for the transience of reunion and the pain caused by separations.
