To tell the truth, because people in these two places live in compact communities and have a high degree of acceptance of their own culture, they also agree, so they form a phenomenon of exclusion and are incompatible with each other;

On the other hand, everyone is more United with each other, especially when wandering outside. Chaoshan has hometown associations and chambers of commerce. We Chaoshan people have a strong sense of local culture, because it is easy for everyone to get together in the relationship of fellow villagers. When one party is in trouble, all parties can help, because with the carriers and channels of hometown associations and chambers of commerce, we can know which ones need help and help each other; Zhanjiang's should be similar;

Between Chaoshan and Zhanjiang, at school, as far as I know, there are occasional contradictions and even fights, sometimes just trivial matters between two people. Later, a quarrel reached a fellow villager and developed into a struggle between two gangs. Sometimes out of passion, sometimes out of face. More likely, everyone thinks that there are many of them, so they should sit on a certain occasion, and no one can obey anyone. Then we must surrender to end this contradiction. That's what I thought!

But the root cause should be discussed from the aspects of regional culture and historical reasons!
