Did the ancestors of the Han people in Vietnam immigrate from the Central Plains in the pre-Qin period?

It is a popular and controversial view that the ancestors of Vietnamese were descendants of Han people who immigrated from the Central Plains in the pre-Qin period. It was these Central Plains immigrants who spread Chinese civilization to Vietnam at that time.

According to ancient records, Qin Shihuang set up a management organization in this area in 207 BC. Since then, Vietnam has been under the direct rule of China feudal dynasty, which is called the county era in history books. In the peasant war at the end of Qin Dynasty, Zhao Tuo, commander-in-chief of Qin Longchuan County, broke away from the rule of Qin Dynasty and established Nanyue State in Lingnan, with its capital in the South China Sea, which is now Guangzhou County, calling himself the King of Nanyue. This is recognized by Vietnamese as the first independent country in Vietnamese history.

In the eyes of some historians, Vietnamese and China people are of the same ancestry, and both are descendants of China people.
