Northeast China is the land of "Longxing" in Qing Dynasty. Since ancient times, in addition to the minority Han people in Liaodong and western Liaoning, the vast areas centered on Baishan Heishui are dominated by ethnic minorities, especially Manchu, Mongolian and other riding, shooting and nomadic ethnic groups. During the prosperous period of Kang Yong's rule, the Qing Dynasty implemented a strict "closed door" policy, forbidding Han Chinese to enter Kanto. After the prosperous period of Kang Yong's rule, the national strength of the Qing emperors became weaker and weaker. Coupled with the invasion of foreign enemies, the policy of "going outside the customs" existed in name only, which led to the tide of "going to the East" in the late Qing Dynasty and the early Republic of China. A large number of people from Shandong and Hebei entered the northeast, bringing the "yangko-based, lotus-based" duet from inside Shanhaiguan Pass to the outside.
