Does anyone know what it means to meet again by chance?

Meet by chance, this sentence is a farewell blessing, in fact, it is very close to the meaning of seeing you later. Generally, when two people meet for the first time, if they hit it off and get along well with each other, then when it comes to never say goodbye, one party will say that it is not meant to be, that is, they hope to meet again in the future and have a good communication. Such words also reflect their nostalgia for each other.
