Why do Cantonese call Jiangxi people cousins?

Jiangxi people are the ancestors of China's southern provinces. Historically, Jiangxi was rich in natural products and densely populated. Due to the sharp increase in population or commerce, Jiangxi people moved to other provinces in large numbers. For example, the ancestors of most people in neighboring Hunan, Hubei and Anhui are from Jiangxi. Jiangxi fills Huguang and Huguang fills Sichuan. A large part of the population who moved to Sichuan came from Jiangxi, or moved directly from Jiangxi to Sichuan when Huguang filled Sichuan.

Many Hakka ancestors in Guangdong came from Jiangxi, and many ancestors of Chaoshan people moved from Jiangxi. In addition to moving from Jiangxi to Guangdong, during the Ming and Qing Dynasties, many Hakkas in Guangdong also moved to the south of Ganzhou, such as the ancestors of Ansu. In 1930s and 1940s, a large number of people in Chaoshan, Guangdong Province fled to Ganzhou, just like the grandmother who answered the Lord. All these relations show that Guangdong and Jiangxi have strong geographical and blood relations, especially the Hakka in southern Jiangxi and the Hakka in northern Guangdong. Therefore, it is not difficult to understand that it is called cousin.
