Pronunciation: láo yàn fēn fēi
Interpretation: "Lao" refers to shrike and "Yan" refers to swallow, both of which are birds; "Flying apart" means that one flies this way and the other flies that way (it can't be written as "flying around"). This is the point of "separation" and "breaking up", which is similar to the meaning of parting ways, but Lao Yan's parting ways emphasize the meaning of "coming together is only accidental, and parting is inevitable", which means it is time to part.
Source: "Yuefu Poetry": "The shrike flies east and the swallow flies west, and the oriole meets the weaver girl."
Synonym: go, go their separate ways, go their separate ways.
Antonym: Luan Xiang Ji Feng, fly with me, the second time.
Ex: After graduation, we will fly together and do our own thing.
