Are the people living in Dandong, Liaoning mainly Han or Korean?

Of course, there are many Koreans, but it's not too many, because after all, most of the Koreans in China are Korean immigrants, and because the Northeast is the birthplace of the Manchu Dynasty, it didn't get great development until the modern Northeast was allowed to open by the Manchu Dynasty. At that time, most Shandong people and Koreans went to the northeast. Because of the close distance between North Korea and the northeast, Korean guerrillas moved in the northeast and needed base areas. So it is conceivable that there are more Koreans, but now it may be balanced because of South Korea, but Koreans still have the advantage.
