In which dynasty did Huguang fill Sichuan? What is the historical background?

At the end of the Ming Dynasty, when the peasants revolted, Zhang captured Sichuan, and all his army generals were knighted according to the number of people killed.

His army killed people in Sichuan, leaving Sichuan thousands of miles away. After Zhang was destroyed by the Qing army, the Qing dynasty saw that there was no one in Sichuan, which was not conducive to detection, so it began to migrate people from Huguang area to settle in Sichuan.
