Didn't all Koreans in China immigrate to China in the late Qing Dynasty and the Republic of China?

In the first stage, during 1700-1869, some Koreans who could not bear the cruel exploitation and natural disasters of the feudal ruling class in Korea still lived in the northeast of China with their families and horses.

In the second stage, with the intensification of Japanese aggression against Korea, a large number of residents moved to the northeast frontier of China in order to find a way out, regardless of the ban of the Korean government. According to statistics, from 65438 to 0870, there were 28 Korean-inhabited towns on the north bank of Yalu River.

In the third stage, 188 1 year, the Qing government set up a famine relief bureau in Jilin and a reclamation bureau in Nangang (Hunchun), Yanji and Donggou to recruit immigrants, all of whom were China subjects.

In the fourth stage, in 19 10, Japan annexed the Korean peninsula, and the Korean people and some anti-Japanese patriots could not bear the cruel oppression and exploitation of Japanese imperialism and moved to the northeast of China in large numbers. 19 18, there were more than 360,000 Koreans in the northeast.

Until the founding of People's Republic of China (PRC), these North Koreans living in China were accepted as China citizens, and they are now North Koreans.
