R How many years did Huguang immigrate in Qing Dynasty?

This is not done at a certain time, but a continuous process, which can reach hundreds of years at the longest, without strict time limit.

It is generally believed that "Huguang fills Sichuan" twice, once in the late Yuan Dynasty and early Ming Dynasty, and once in the period of Kang Yong.

Immigrants in the Qing Dynasty lasted for more than 100 years, and the number of people entering Sichuan was about one million, of which Hubei and Hunan provinces each accounted for half. Roughly in the thirty-third year of Kangxi (A.D. 1694), an imperial edict named "Recruit People to Fill Sichuan in the Thirty-third Year of Kangxi" was officially promulgated. Since then, immigration has been regarded as a government act (there have been spontaneous immigrants before), which lasted until the Qianlong period.
