Why are there so many Vietnamese surnames Nguyen?

Because of the war between the Ming Dynasty and Vietnam, Daming overthrew Hu and ordered all people surnamed Hu to change their surnames to Ruan. Moreover, the last emperor of Vietnam was surnamed Ruan, so Ruan became the first surname in Vietnam. There are many surnames in Japan, so you can choose your name at will. They choose their names according to the things around them, that is, no matter where they live, they are called. If you live in a field, it's called Tian, and if you live by the ferry, it's called Watanabe. Korean surnames are very concentrated, not as sparse as Japan. Most Korean surnames are Kim, Lee and Park.

When it comes to concentration, the most concentrated surname is Vietnam, and 40% of Vietnamese are surnamed Ruan. Because of this, the name Ruan ranks among the top ten in the world. Although there are many Vietnamese surnames Nguyen, there are less than a few hundred surnames China. Speaking of Ruan, I think of Ruan Cishan, a famous person in China.

In fact, the Nguyen surname of Vietnam was handed down from China, because Vietnamese aborigines did not have their own surnames, and Vietnam has been a vassal of China for thousands of years. During the pre-Qin period, a large number of people immigrated to Vietnam. After the ancient Shu kingdom was destroyed by Qin, the King of Shu led 30,000 people to Vietnam to rebuild the country. These 30,000 people not only brought technology and culture, but also brought their surnames.

During the Wei and Jin Dynasties, there was a famous celebrity named Ruan Ji, one of the seven sages of bamboo forest and one of the seven sons of Jian 'an. In order to survive, Ruan family went all the way south and settled in Vietnam. During this period, Nguyen expanded, Vietnam became accustomed to the arrival of foreign surnames, and Vietnam became the best place to accept Nguyen.
