People in Huaibei, Shandong, Hebei and Henan died ten times, seven or eight times, so that "a hundred people stayed behind, and there were no crows thousands of miles away." The wounds of the war at the end of the Yuan Dynasty were not healed, and the "Battle of Jingnan" followed in the early Ming Dynasty. Hebei, Shandong, Henan, Anhui and other places have suffered greatly, and almost all of them are uninhabited. During the war at the end of Yuan Dynasty, Shanxi, which was ruled by Chahan timur and his son, was a different scene. Relatively stable, bumper harvest every year. Compared with neighboring provinces, it is prosperous in economy and population. A large number of refugees from other provinces flowed into Shanxi, and Shanxi became a densely populated area. After the Yuan Dynasty was destroyed in the Ming Dynasty, in order to consolidate the new regime and develop the economy, eight large-scale immigration activities were organized in the nearly 50 years from the early years of Hongwu to the fifteenth year of Yongle, involving 882 surnames in more than 490 counties and cities in 18 province.

In the Ming Dynasty, mop.com set up bureaus under Guangji Temple and Sophora japonica to handle immigration matters, and Sophora japonica became a gathering place for immigrants. When the immigrants left, they stared at the ancient pagoda tree, and the old stork who lived among the branches kept moaning, which made the immigrants who had left their homes cry and could not bear to leave. To this end, the locust tree has become a symbol for immigrants to bid farewell to their hometown. In the early Ming Dynasty, the immigrants who moved out of Hongdong and other places in Shanxi mainly distributed in Henan, Hebei, Shandong, Beijing, Anhui and Jiangsu, and a few moved to Shaanxi, Gansu and Ningxia. Immigrants who moved from Shanxi to the above places later moved to Yunnan, Sichuan, Guizhou, Xinjiang and northeast provinces.
