Did Korean ancestors originate from Han nationality?

Koreans are immigrants, not native minorities in China. It has been nearly 100 years since Koreans immigrated to China.

/kloc-In the middle and late 20th century, there was a great famine in Korea, and a large number of Korean refugees entered the northeast of China and the present Yanbian area to make a living. Since then, Korean refugees have been pouring into the northeast to reclaim land and colonize. After the merger of Japan and South Korea, Japan began to implement the strategy of colonizing the Northeast with fresh people in an attempt to "freshen up" the Northeast. After the "September 18th Incident", Northeast China fell into the period of Japanese puppet rule. After Japanese imperialism invaded the northeast of China, it adopted an extremely sinister strategy of "governing China with food" and formulated a "Korean immigration plan" to move a large number of Koreans to various parts of northeast China. 1936 In August, the puppet Manchukuo government and the North Korean Governor's Office jointly formulated the Manchurian Korean Code, agreed to immigrate from North Korea 1 10,000 households every year, and decided to regard Korean immigrants as "constituent elements" of Manchukuo nationals. Only in the five years from 1937 to 194 1, 24,468 Korean immigrants moved to all parts of Northeast China. According to Jones's "Northeast China after 193 1 year", "before the recovery of China's northeast in 1945, there were as many as 3 million Koreans living in the northeast of China, which was more than 5% of the total population in the northeast." 1945 After the recovery of the People's Republic of China on August 15th, some Koreans living in China moved back to the Korean Peninsula, but a large number of Koreans still stayed in China.

After the founding of People's Republic of China (PRC), the China government granted these Koreans in China China nationality and minority status for humanitarian reasons.
