Are Vietnamese descendants of Han nationality?

Vietnam is also divided into many ethnic groups, and the Jing and Chinese ethnic groups are stronger. So to answer lz's question, we should start from the origin of the yellow race. The earliest yellow people originated in Tibet and Yunnan-Guizhou Plateau. During the Ice Age, some yellow people from Yunnan-Guizhou Plateau entered Myanmar, now Vietnam, which is called Baipu ethnic group in ethnology. Those who have settled in Vietnam now have become the Jing nationality, that is, the relatively standard Vietnamese image we usually see, and have a deep blood relationship with the residents of Guangdong Province in China. Another yellow race migrated northward after the Ice Age and settled in the Central Plains of China, becoming what we call the Han nationality. However, with the development of the Chinese nation, some businessmen or craftsmen immigrated to Vietnam and settled there. They are descendants of the Han nationality in Vietnam and are called Chinese in Vietnam. Although they hold the considerable economic lifeline of Vietnam (especially Ho Chi Minh City), they only account for 1.2% of the Vietnamese population.
