Why have many Northeasters emigrated to China and abroad in recent years?

Economic factors are the primary consideration of population mobility. Statistics show that in addition to Sanya, which is famous for its large population in the northeast, the main areas of population outflow in the three northeastern provinces are Beijing, Tianjin, Hebei, Shandong and other places. In addition to domestic immigrants, in recent ten years, more and more Northeasters have emigrated overseas through various channels, and gradually compared with the traditional immigrants from Zhejiang, Fujian, Guangdong and Hongkong.
