Sanhan immigrants

Donglai refers to the northern part of Jiaodong Peninsula, and the Korean Peninsula is covered by the circle of Chinese civilization, so there are undoubtedly China immigrants there, and it is very close to Jiaodong Peninsula, which can be described as separated by a strip of water and facing each other across the sea. Therefore, it is more likely to immigrate from Donglai-but history needs rigorous textual research to determine. However, Dongyi is an indigenous people in ancient southeast coastal tribes. Dongyi is the title of the people in the marginal areas in the Central Plains. At that time, it was uncivilized and less civilized than the Central Plains, so it was called barbarians. Therefore, the Korean peninsula has nothing to do with the title of Dongyi.
