/kloc-Wei Yuan, a famous historian and geographer in the 20th century, summarized the main migration trend of China in the Qing Dynasty as "filling lakes in Jiangxi".

During the Chongzhen period of Ming Dynasty, due to the peasant uprising of Zhang, there were frequent wars in Deyang area. In the sixteenth year of Kangxi, the Qing army killed innocent people in order to destroy the rebels, and the population was exhausted and deserted. According to the decree of the Qing court, many residents in Jiangxi, Hunan and Hubei were forced to move. People call this great migration "Jiangxi fills Huguang and Huguang fills Sichuan".

From Yongle period of Ming Dynasty to early Qing Dynasty, immigrants from Jiangxi and other provinces moved into Hunan and Hubei. Although it is not as violent as the Hongwu period, the total amount is still considerable because of the long time. These immigrants mainly seek economic development. In addition, the wasteland of the two lakes can be reclaimed at will, and some people voluntarily immigrate to Huguang because of the heavy taxes in Jiangxi, unlike the government forced people to immigrate to Huguang during the Hongwu period. Compared with Hongwu immigrants in the early Qing Dynasty, the scale of this immigration climax is smaller. Because after hundreds of years of development, the population pressure of the two lakes has already appeared. When immigrants from Jiangxi and other provinces moved westward, many people in the two lakes moved westward in order to find better development opportunities, forming the famous "Huguang filling Sichuan" immigration movement.

War is only an external thrust for the migration movement of more than 1000 years to continue to develop. The fundamental reason is that the economic development of Hunan and Hubei lags behind that of Jiangxi, Anhui, Jiangsu and Zhejiang, and there is quite broad room for development to accept immigrants. Therefore, the process of migration is also the process of the development pattern of the Yangtze River basin gradually expanding from east to west.
