Where did the Han nationality in Jiaojiang, Quanzhou, Guangxi come from?

Inland. Because of Qin Shihuang's reunification campaign, Lingnan was incorporated into the unified territory, and troops and businessmen were sent to Guangxi. In addition to stationing a large number of troops in the local area, many Han people went to Lingnan from Zhongyuan. This is the original immigrants who claimed to be Han Chinese, and the number reached nearly 600,000, which also formed the earliest Han ancestors who came to Guangxi. So the Han people in Jiaojiang, Quanzhou, Guangxi are from the mainland.
