Sichuanese immigrated from there.

Most Sichuanese should have moved in during the migration from Huguang to Sichuan. Huguang filling Sichuan refers to two large-scale migration waves that occurred in China in the late Yuan Dynasty, the late Ming Dynasty and the early Qing Dynasty. Residents from Hunan, Hubei (namely Huguang Province) and Guangdong (mainly Hakkas) migrated to Sichuan and southern Shaanxi. According to research, there are also residents from more than a dozen provinces such as Jiangxi, Fujian and Guangxi.

During the last 30 years of the late Ming and early Qing dynasties, Sichuan suffered from frequent wars, famines and plagues, which led to a sharp drop in the population of Sichuan. According to research, the population of Sichuan in the early Qing Dynasty was only about 500,000, and there were only a few hundred households in Chongqing (now Chaotianmen to Qixinggang Tongyuanmen). There are only a dozen people left in some counties under the jurisdiction of Chongqing. Kangxi ordered to encourage large-scale immigration to Sichuan (including Chongqing), and the Qing government also promulgated a series of preferential immigration policies for this purpose. Let immigrants from Hunan, Hubei, Guangdong, Henan and other provinces migrate to Sichuan. In the late Ming and early Qing dynasties, the population of Sichuan withered because of the resistance to Mongolia and Qing Dynasty. However, after hundreds of years of population and economic recovery, Huguang Province began the second large-scale migration to Sichuan, especially from Hubei and Hunan, most of which were from Macheng, Hubei.
