The Distribution of Surname Culture in China

First, the inheritance of China people's surnames in history is continuous and implicit. It reveals that in the course of history, the traces of consanguineous culture expressed by China people's surnames are basically consistent with the evolution of life genetic material, especially paternal genetic material, and the expression of traditional culture in China.

Secondly, China has always had the custom of cohabitation with the same surname and genealogy, with a small marriage radius and relatively fixed marriage area, thus forming the distribution of people with the same surname. The distribution of surnames in China mainly reflects the distribution law of people with the same surname. There are two surnames or people with the same surname in China, that is, a big surname and a small surname, or a common surname and an unusual surname. Ordinary 100 surnames, which account for less than 5% of the total surnames, account for more than 85% of the population, while unusual surnames, which account for more than 95% of the total surnames, only represent less than 15% of the population. The distribution of 100 common surnames is the main factor reflecting the genetic composition of people in different regions, which determines the scale of population migration in China history and the degree of kinship among people in different regions. People with unusual surnames show their regional characteristics and relatively high degree of isolation.

Third, the main direction of population migration reflects the flow of China people's genes. At the same time, from the perspective of population genetics, it is once again confirmed that there have always been two Han populations in China, the north and the south, which are genetically different, and the geographical dividing line of 1000 should be in Wuyishan and Nanling. Therefore, studying the distribution of surnames and people with the same surnames in China may become a new and important way to explore the origin of China people, especially the evolution of paternal genetic material.
