Did China's ancient South Vietnam disappear?

South Vietnamese people have not disappeared, and this ancient nation has evolved into many ethnic groups in modern Lingnan area. Nanyue people, a branch of Baiyue in ancient times, are an ancient nation with strong cultural characteristics, living in Lingnan, mainly distributed in the Pearl River Basin and Hanjiang River Basin. With the continuous large-scale migration of Central Plains people to the south, the indigenous South Vietnamese and the Han people lived together for a long time, and most of the indigenous people gradually merged with the Han people, eventually becoming Chinese. The non-Chinese aboriginal settlements are gradually decreasing. These indigenous people later evolved into Li, Zhuang, Yao, She, Miao and other ethnic minorities, retired to the mountains and distributed in Guangdong, Guangxi, Hainan, Yunnan and other places in China. The Jing nationality, the main ethnic group in Vietnam, is also directly related to ancient South Vietnam.
