What is the contradiction between Chaoshan people and Zhanjiang people?

Mainly fighting at school .. rarely going out of society. ..

Zhanjiang is actually Leizhou ... I'm from Zhanjiang ... but not Leizhou. My friend got along well with Chaoshan people when he was at school ... and often drank tea. ..

Mainly because people in these two places and many fellow villagers go to the same school ... so whenever something happens, everyone will call people out ... If they don't fight, it's useless ... Then people in the school fight ... So do people in another school. Come back after reading and talk to those who just went out to study ... and the problem between the two groups is getting bigger and bigger ... even if the other party does nothing ... it will be solved.

I don't know what to say about your guess .. I don't know the previous history, but I don't think there will be such a thing.
