There are some brown genes and short black genes in the ethnic origin of Korean-Japanese. There are 30% to 40% brown genes in Korea, 40% dwarf black genes (albinism) in Japan, and the rest are mainly M 175.

The main characteristics of brown people are pie face, flat face, squint eyes and triangular eyes. Short and black is characterized by short stature and small and round face. Brown and short black are ancient genes that evolved 50 thousand years ago.

However, the Y chromosome of China Han people can hardly find brown, short and black. More than 90% of the genes were differentiated in the last 10,000 years. From the gene tree, Han people (mainly M 175) and Aryans (M 173) are cousins and Nordic people (M23 1) are brothers. And short black (YAP) and brown (M 130) can be understood as great-grandfather's brother or his descendants.

The main feature of China people's eyes is the phoenix eye (also a kind of squint eye). Among the Han people, double eyelids account for an absolute majority.

In addition, it is worth mentioning that the change of soft tissue properties and skin color is relatively easy. In order to adapt to the environment, great changes can take place in 1000, and African-Americans are much whiter now than in the past. Therefore, it is not very scientific to define ethnic composition by the shape of eyelids. Nordic people arrived in Europe relatively late from Asia, but they are quite different from us in appearance, aren't they? However, if we compare the shapes of noses and heads between northern Europeans and China people, we can find that they have more similarities.
