In the Tang and Song Dynasties, with the change in the political system and the southward shift of the economic center of gravity, The scale of immigration from north to south has been expanded at an accelerated pace and the process of national integration has also accelerated. Its main manifestation is the formation of the minorities in the south of the Han nationality and the maturity of some southern minorities, laying a new pattern of ethnic relations in the south. Due to space limitations, this article only briefly discusses the formation of two Han Chinese civilians such as the bosses and Hakkas in Southeast and South China.
