How did Chaoshan people come? Is it divided into several areas?

According to documents, the ancestors of modern Chaoshan people came from the Han nationality in the Central Plains. It can be traced back to the Qin Dynasty (about 2 14 BC), when Qin Shihuang sent troops to unify the southern region into a China. This is considered to be the beginning of the transfer of the Han nationality in the Central Plains from the central region to the Chaoshan region. The second large-scale southward migration of the Han nationality in the Central Plains took place in the Western Jin Dynasty in 265-3 16. With the so-called Yongjia Rebellion, serious natural and man-made disasters spread all over the ancient Central Plains, forcing people to flee everywhere and move to the vast and peaceful south. During this period, Han immigrants from the Central Plains gradually influenced the indigenous people in the south in various ways. Until the end of Song Dynasty and the beginning of Yuan Dynasty, almost all the aborigines in Chaoshan area were assimilated by Han people in Central Plains. It should be pointed out that from a historical point of view, the Han nationality in the Central Plains did not move directly into the Chaoshan area. Instead, they settled in Fujian first and then gradually moved to Chaoshan area.
