Korean nationality is one of the cross-border ethnic groups in China, which was gradually formed when the neighboring Korean Peninsula moved in and settled in the northeast.

1982 during the national census, it was found that some Korean ancestors settled in North China and Northeast China as early as the late Ming and early Qing dynasties. For example, in Tagou, Qinglong County, Hebei Province, and Pujiagou Village, Gai County, Liaoning Province, Han surnamed Park has settled in the local area for more than 300 years.

Since the middle of19th century, more and more Koreans have moved in from the Korean peninsula, which is the main source of Koreans in China. Due to the cruel exploitation and oppression of the feudal ruling class in Korea at that time, especially the natural disasters in northern Korea for several years around 1869, hungry and cold Korean farmers left their homes one after another, crossed the Yalu River and Tumen River and came to China to reclaim land in the two rivers and live with the Han and Manchu people.
