Chu people migrated to Lingnan.

During the Qin Dynasty, most of the Qin Jun in Lingnan were Chu people recruited nearby, and even later there were fewer and fewer Qin people in the army. So don't say it's back support. It would be nice not to go north to destroy Daqin.

After Qin Shihuang unified the six countries, he took a fancy to Lingnan area. Then he personally led an army and brought all the areas north of Vietnam into the territory of the Qin Dynasty. Since then, Lingnan area has become a part of China. Qin Shihuang left 500,000 Qin Jun in Lingnan area, while fighting bandits and developing production in Lingnan area. But it didn't take long for the Qin Dynasty to face extinction. Qin Jun in other border areas went back to support, while Qin Jun in Lingnan did not send a single soldier.

Most people want to know why Qin Jun, who left Qin Shihuang in Lingnan, didn't go back to rescue him. If he had done so, the Qin Dynasty might not have perished. This problem has also become a puzzle in history. Some people say that it was because Qin Shihuang left them an order that no matter what happened in the imperial court, they were not allowed to go back. But this statement is unrealistic. If Qin Jun in Lingnan is from A Qin, he heard that his hometown was besieged. How could he not go to the rescue? So, this order can't be true.

According to many buried objects found in Guangdong and Lingnan areas of Guangxi. According to experts' research, the funeral culture of Qin Dynasty is almost nowhere to be found in Lingnan, and it is all the funeral habits of Chu people. In this way, when Qin Shihuang conquered Lingnan area, most of them were Chu people, so Qin Jun in Lingnan had no opinion of the Qin Dynasty, so he would not support it when the Qin Dynasty perished. It is precisely because of their ambition that they neither saved Qin nor returned to Chu, but established their own country-Nanyue State.
