What are the Korean names? How did it come from?

The seeds are sealed there. The Spring and Autumn Period was the land of Yan State, when South Korea was underdeveloped. According to historical records, korean king of the Han Dynasty was a native of Yan. Qin destroyed Yan, and Yan people basically moved to the south of Korea. During the China chaos, a large number of Han people went to Hexi Corridor and Liaodong. Liaodong includes not only Liaoning, but also most parts of North Korea. At that time, Zhongyuan people fled to the south because of the war, and so did Liaodong people. It is absolutely no accident that there are compound surnames such as Nangong, Zhuge and Huangfu in North Korea. There are not many surnames like China. It can be seen that 90% of Koreans are immigrants from the Central Plains. Most of them are Yan immigrants. It is said that this Korean surnamed Kong comes down in one continuous line with Kong's family in Qufu, Shandong, China.
