Where did many Chinese immigrants to Guizhou come from during the Ming and Qing dynasties?

During the Ming dynasty (1368–1644) and the Qing dynasty (1644–1911/12), the Chinese government implemented colonization policies that encouraged significant migration into Guizhou. Many of these immigrants arrived from the provinces of Hunan, Jiangxi, and Sichuan, settling primarily in the central, northern, and eastern regions of the province.1
