A pair of feet bear the weight of our entire body, help us to go anywhere we want to go, but compared to the hands people tend to ignore the feet, and because the feet need to wear shoes, long-term wrapping so that the feet will emit a strong smell, which is also known as foot odor, making people think that the foot is a dirty part.
In daily life, many women pay attention to the maintenance of the hand, do a variety of nail art, and make hand masks. As everyone knows, having a pair of beautiful feet is also particularly important for the overall image of people, especially when wearing slippers or sandals in the summer, a pair of white feet can add a lot of points.
I wonder if you have carefully observed your feet in life, and what is abnormal about your little toenails? Speaking of which, many people will suddenly think that their small toenails are divided into two things, is this a disease or a congenital malformation?
In medicine, the situation in which the small toenail cover is divided into two lobes is called the flap nail, which is a professional term that is really smooth to call, and the flap nail is a unique saying in ancient times.

Statement 1
It is said that during the Hongwu period of the Ming Dynasty, in order to supplement the regional population decline caused by a large number of wars, the government asked the people of Shanxi to move out, but the people who had lived in Shaanxi for generations were reluctant to immigrate.
Hindered by the pressure of the government and the power of some local officials, they also embarked on the road of immigration, and then secretly escaped in the middle of the road, but they did not expect that there was a mountain outside the mountain, and there were people outside the people, and the officials had long thought of this problem, so they cut a knife on the cover of everyone's little toe as a marker, which was easy to find and punish in the future.
So until now this saying has been slowly handed down, the small nails divided into two halves of people are the descendants of Shanxi people, but after all, it has been handed down through the ages, and there may be changes and exaggerations in the process of inheritance, which is not clearly stated in the historical records.

Statement 2
Some people regard the flap armor as a symbol of ethnicity and place, which is a unique feature of the Han people, but some scientists have also done research, collected data from 720 Xinjiang Uyghurs, and found that the incidence of semi-strong armor among the Uyghurs in Xinjiang is 52%, and the probability of 58% of the Han people is very similar, so the valve armor is a unique feature of the Han people, which is wrong.
Even studies of the race of flap armor were randomly selected from China, Switzerland, Norway, Portugal and other countries, but the results of the survey showed that semi-armor was not a trait of a certain nation or country, but a global feature.

Fudan University's study of Shanxi flap nails
The petal-like nail originated from the legend of the large locust tree in Hongdong, Shanxi in the Ming Dynasty, and a professor at Fudan University investigated and studied the petal-like nails of people in some areas.
Unexpectedly, this study did find a problem, the distribution of the petal nail has a certain relationship with Shanxi immigration to a certain extent, the general relationship is as follows: taking Shanxi as the starting point to the southeast direction shows a decreasing trend, the probability of the number of petal nails has dropped from 79.1% to 37%, which is consistent with the historical migration situation in Shanxi.
This can only mean that the flap armor has a certain regional influence, and does not prove the relationship with race or even ethnicity.
04
From a scientific point of view, what is the cause of the flap nail?
From a medical point of view, the valvular nail is a hereditary physiological phenomenon, which is autosomal dominant inheritance. And the flap nails will continue to grow with the growth of the human body, such as babies when they are born without armor, and do not appear until they reach a certain age.
Although the heritability of the valvular nail is only 70%, not 100%, the children born to parents with flap nails do not necessarily have such a problem, and it is not related to the gender of men and women.
05
Are flap nails harmful?
Flap nails are a normal phenomenon and generally have no harm, but if you feel uncomfortable wearing shoes, or affect your appearance, you can perform nail extraction surgery through a regular hospital to let them re-lengthen their nails.
People with flap nails should wear some loose and comfortable shoes in daily life, trim their nails regularly, and avoid scratching because the nails grow too fast, resulting in deformation of the toenails. If it is allowed to grow wildly, it is likely to cause redness and swelling of the child, a local infection, and a serious and may cause paronychia, at this time you need to go to the hospital to unplug it.
