What is the origin of people whose little toe nails are split in half?

These people whose little toe nails are split into two halves are Shanxi people who migrated to the Central Plains during the Ming Dynasty. They did this to distinguish themselves from other residents, but with this It is unscientific to differentiate between races. This phenomenon is related to genetics.

From ancient times to the present, we have generally relied on some external characteristics to distinguish people of different races. The skin color of yellow people is yellow, the skin color of black people is black, and the skin color of white people is white.

In ancient times, there was another way to distinguish them, which was to distinguish them by the shape of their little toes. Some people’s toenails on their little feet were separated. According to medicine, this was a type of nail that grew due to friction. formed from cocoons.

This way of distinguishing comes from a story. During the Hongwu period of the Ming Dynasty, the population of the Central Plains region was greatly reduced due to war. At that time, in order to quickly increase the population, Shanxi, which had a larger population, was People who have lived in Shanxi for a long time are certainly unwilling to move to the Central Plains, but they dare not resist and can only comply.

So in order to distinguish them, during the migration process, the soldiers cut off the little fingernails of the people who migrated from Shanxi. These people with cracks on their toenails were from Shanxi. Immigrated to the past.

However, this method is not valid according to scientific basis. Several people in some families may have different conditions, which may be related to genetic inheritance.
