Korean ancestors came from which dynasty in China?

Historically, South Koreans have migrated to North China for a long time. Koreans have also immigrated to China many times.

China people immigrated to North Korea on a large scale in history, mainly as follows:

1, when there were few Koreans. During the Shang and Zhou Dynasties, Ji Zi, a noble of Shang Dynasty, led 5,000 Shang Dynasty people to move eastward to Korea and established Jizi Korea. This is the earliest civilized regime in North Korea.

In Qin dynasty, many people fled to the south of Korean peninsula to escape the tyranny of Qin Shihuang.

3. In the early Han Dynasty, Wei Man and other Youzhou people invaded Korea, overthrew the ji zi regime and established Wei Man Korea.

4. After Emperor Wu of the Han Dynasty destroyed Wei Man Korea, a large number of immigrants migrated to the northern part of the Korean Peninsula for a long time. This process lasted until the Western Jin Dynasty more than 300 years later.

5. The Tang Dynasty destroyed Koguryo and annexed the northern part of the Korean Peninsula, with the Datong River as the boundary and Silla as the south. The Tang Dynasty immigrated to the north of Datong River for a long time.

6. When Mongolia invaded China, a large number of South Koreans fled to North China.

7. When Manchuria invaded China. A large number of Koreans fled to the north of China. Now the genealogy of North Korea records that many people's ancestors were in the Song Dynasty or the Ming Dynasty.
