Dear arnold, I don't know if my ancestral lineage is Chinese. From time immemorial, Koreans interacted with Chinese, Manchus, Mongolians, and Japanese. So, mixed blood and cohabitation between them and Koreans frequently occurred.
I am amazed that Americans know about their ancestors well.
The reason Vietnamese people like Koreans and Japanese people is that they have long grudges with Chinese people.
China colonized Vietnam for 1000 years.
I don't know how many people know but I've studied how all the people on the planet can be traced back to the three sons of Noah, the oldest son, Japheth, I think his descendants migrated towards Europe, the middle son, Shem, his kids stayed around the Middle East and Asia in general, and the youngest, Ham, his children started moving towards Africa. But over the years, there were many interracial marriages between the three main races of white, yellow, and black. So, it can be pretty simple and also very complex to follow the history of genealogy for the humans of the planet. I was watching a series all about this early in 2020 by none other than Answers in Genesis. Vietnamese don't really have to be against the Chinese people but I think some are or maybe many are. But the real problem has been the Chinese government itself. The most popular last name in Vietnam is Nguyen.
The Bible says that mankind originated from Noah's three sons. That is an interesting argument, but Mongolians in East Asia are genetically distant from the descendants of Shem. In Genesis, not only the descendants of Noah, but also the Nephilim, a mixed race of angels and humans. Some argue that the Nephilim are a mixed race of aliens and humans.
Only God will know the truth!
Nguyen is probably the last name of the king of Vietnam, who made Vietnam independent by fighting China.
The Bible talks about Adam and Eve and then later on Noah. The Nephilim were around before the world flood. So, some people say the Nephilim died in the flood. Some suggest there are giants and other things hiding in the hollow earth. I don't really know what is inside the planet. Nguyen may have been a Vietnamese king but I have heard stories regarding that man being a descendant of Chinese people or that he was fully Chinese. It may have been during the time China invaded and occupied Vietnam.
It is said that the ancestors of the Vietnamese originated in China.
