The ethnic evolution of Sanhan.

The main members of the residents in the southern part of the ancient Korean peninsula were Koreans. There are three kinds of Korea, namely Mahan, Chen Han and Han Ge. Chen Guo is one of the cradles of ancient Korean culture, and its residents are mainly Koreans. Chen may be an older and looser tribal association, rather than a national form.

In the process of its formation, the Korean nation took Koreans as its absolute subject, and then absorbed the Han immigrants from China who moved eastward to the south of the Korean peninsula and the Japanese who crossed the Japanese archipelago to the Korean peninsula, thus forming the Korean nation.
