Where did the massive migration of Jiangxi population to Huguang originate?

The large-scale migration of Jiangxi population to Huguang originated in the late Yuan Dynasty and early Ming Dynasty. According to relevant data, due to political and economic reasons, a large number of Jiangxi people moved into Huguang area, which is now Hunan and Hubei provinces. This is a large-scale immigration activity. After the Yuan Dynasty was destroyed in the Ming Dynasty, in order to consolidate the new regime and develop the economy, eight large-scale immigration activities were organized during the fifty years from the early years of Hongwu to the fifteenth year of Yongle, forming the famous Huguang Movement in Jiangxi.
