What is the origin of two petals of little toenail?

It is normal for the little toenail to have two valves without any source. The bifurcation of the little toenail is called epiphyseal nail and epiphyseal toe, and the scientific name is petal nail. This can happen to men and women. Some scholars have investigated the distribution of petaloid nails in rural areas of Shanxi, Shaanxi and Henan provinces. The results showed that the frequency of petaloid nail was the highest in Shanxi, reaching 79. 17%.

People whose little toe nails are petal-shaped nails belong to the majority in China, and it is a genetic trait. If the child has petal nails, then generally speaking, at least one parent has petal nails.

Legend has it that the little toenail will be divided into two petals.

1, which means that the knife cuts nails.

In some folklore, petal-shaped nails are related to the great immigrants from Shanxi in the early Ming Dynasty. China people have a strong local complex, and many Shanxi people who set foot on the road of immigration are trying to escape back to their hometown.

The officers and men racked their brains to prevent escape, and some magical sayings circulated among the people. Among them, the knife is widely used to cut nails. It is said that the officers and men cut a knife on the little toe nail of the immigrants, which can not only prevent them from escaping, but also facilitate the immigrants to recognize their relatives in the future.

2. Friction genetic theory

There is a friction genetic theory that is more reasonable than cutting nails with a knife. In ancient China, 5,000 years ago, people engaged in agricultural work for a long time, but without these professional and tenacious agricultural equipment, the fragile little toe nails were often rubbed. Under long-term friction, the little toe nail cracked, from one flap to two or three.
