When did Jiangxi fill in Luzhou, Sichuan?

Jiangxi filled Luzhou, Sichuan in the 16th year of Kangxi, that is, 1677. Years of wars at the end of Yuan Dynasty and the beginning of Ming Dynasty made the rural areas of Changsha desolate, scattered, Lusheng a city, and many places deserted. As a result, the Ming Dynasty moved a large number of Jiangxi immigrants to Changsha (Hubei and Hunan, when the two provinces were one province, called Huguang Province), and allowed flags to be planted to occupy an area, which staged a grand epic of Jiangxi's filling in Huguang in history. 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 filling Huguang and Huguang filling Sichuan.
