The main period of Huguang filling Sichuan occurred from the 21st year of Qianlong (1756) to the 34th year of Qianlong (1769). At that time, Sichuan had no policy to increase taxes, it was difficult to collect taxes, and the population decreased sharply. Therefore, the central and local governments at all levels took a series of measures to attract foreign immigrants, of which Huguang province had the largest population.
After the unification, the Qing government implemented a series of policies of "filling Sichuan"; Mainly to encourage immigrants from other provinces to enter Sichuan for reclamation. If it is stipulated that those who wish to enter Sichuan will give an acre of land for eternal business. Those poor people in all provinces who bring their wives to Sichuan are allowed to naturalize. The preferential policy for recruiting people into Sichuan is closely related to the promotion of political achievements of officials at all levels and the encouragement of land reclamation; Implement additional preferential tax policies.
Kangxi issued an imperial edict to levy taxes on mu of land reclaimed by immigrants from five years. And never impose taxes on the breeding population. It also provides for the authorities of the immigrant origin and the authorities who enter the Sichuan settlement authorities to arrange for the registration and registration of the registered residence. These policies have created a good environment and conditions for immigrants.
