People with little toes are half Han Chinese, half Huns and half Xianbei people? Why is there such a statement?

The little toe divided into two petals is medically called petal nail, also called compound nail, toe nail and so on. It is a slight defect of the little toe and does not affect the physiological function. This is because there are two folklores, and this physical feature is related to nationalities, one is Sophora japonica and the other is Li Shimin Jia Jian.

It is believed that the compound nail is inherited by Xianbei people

Legend has it that Li Shimin was the first person to elevate the composite nail to the racial level. Then he found that his nails had two petals, which was very strange. He ordered people to check everyone's toenails in the palace. Later, it was found that only half of the people in the palace had this phenomenon. He thinks this compound nail was inherited from Xianbei people because his biological mother is Xianbei people.

People think that Fu Jia is a symbol of pure Han people. Legend has it that after Zhu Yuanzhang established the Ming Dynasty, he decided to move the population of Shanxi to the south to promote the development of the south. These adherents were very reluctant to leave their hometown, so they concentrated under the big locust tree in Hongtong County and cut a knife on their little nails. Since then, all the rehabilitated people are descendants of the big locust tree. Because the Yellow River is the birthplace of Chinese civilization, it has also been promoted to the height of pure Han people.

3. Evidence of racial discrimination This sentence comes from the last Hun in the novel. A Han woman fell in love with a Xiongnu soldier and became pregnant with a child. The villagers tried to hang the soldier when the Han woman was pregnant. So people decided to have a baby. If it is a compound nail, it is a descendant of Han people, and if it is a smooth toenail, it is a descendant of Xiongnu people. Later, the son was born with smooth nails and was executed.

Anyone with a little knowledge of biology knows that a knife wound can never be passed on to the next generation. If this can be inherited, then Korean girls are not afraid to have babies after plastic surgery. In 2005, the School of Public Health of Fudan University counted that there was a village in Shanxi, Shaanxi, Henan, Jiangsu, Zhejiang, Jiangxi and Fujian provinces, and the result was very close to the legend. The re-nailing rate is 79. 17% in Hongdong County, Shanxi Province, 62.45% in Huai 'an City, Jiangsu Province, and only 37.80% in Yongtai County, Fujian Province, which is at the southernmost tip.

From this point of view, it seems that the gene of Compound A spread slowly with the southward migration of Sophora japonica, but the scientific nature of this data is still questioned by other scientists. This statistical sample size is small, and it is concentrated in one village, and the error is too big. For example, in a village in zhouzhi county, Shaanxi Province, only 78 households with 3 12 people participated in the survey. Therefore, as evidence of the inheritance of Sophora japonica, it is not convincing enough.

Why don't we look at the western medicine's explanation of compound nail? Westerners believe that compound nails are caused by the friction between feet and shoes, more like cocoons.

There are two reasons for nail duplication, one is hereditary, the first joint of the little toe is stiff, the mobility is reduced, or the little toe is everted, resulting in great friction with shoes, and this toe deformity gradually appears. Another reason is also the influence of the acquired living environment. If you live in the countryside, often engage in agriculture and need to keep walking, there may be a phenomenon of compound nail in a village.
