However, Cavalli Sforza's research in the early 1990s showed that the Yangtze River was the main obstacle to gene exchange between people in Northeast Asia and Southeast Asia. His research pided the people of southern China into groups with Vietnamese and other Southeast Asians.
然而，卡瓦利·斯福尔扎（Cavalli Sforza）在90年代的早期研究表明，长江是东北亚人和东南亚人之间基因交流的主要障碍。他的研究将中国南方人与越南人和其他东南亚人分为一组。

Vietnam is a country located in the Southeast Asian Peninsula region, with a population of nearly 100 million and 54 ethnic groups. The largest ethnic group in Vietnam is the Jin nationality, but also known as Vi , accounting for 86% of the country's population. The Jin nationality itself is a cultural center nation, not a genetic center nation. The Jin nationality can be considered as the Romans. People become the Jin nationality while accepting the Jin culture and nationalism. This explains the appearance, customs, habits and cuisine of the Jin people in all provinces and regions.
