Where do people have irregular toes and nails? I heard that these people are all from the same place, so I want an authoritative basis.

Your question is very interesting! Let's talk about the legend of "six toes" first. Many people of Han nationality in China have their little toes split in two, and the outer one is smaller. It is said that in Linfen, Shanxi, an ancient primitive tribe, people had six toes on each foot, and then the two little fingers were combined for a long time, but the nails of this little finger were not completely combined.

Let's talk about a famous pagoda tree in Hongdong County, Linfen City, Shanxi Province. In the Ming Dynasty, China organized 18 large-scale immigrants by the imperial court. At that time, many immigrants from Shanxi concentrated under the locust tree in Hongdong and then moved to other provinces in batches. Now it is found all over the country. Because people who came out of the locust tree at that time usually had two little fingers with nails, maybe this gene has been passed down to the present. Therefore, there are still many old people who often say to their friends, "I am a person who came out under the big locust tree in Hongdong, Shanxi"! Because they all have little toes with two nails.

There is also a wider legend: it is said that when people immigrated, officers and men cut each little toenail with a knife. So far, the little toenails of the descendants of immigrants from Sophora japonica have two petals. "Who is the ancient locust immigrant, taking off his little toe to check the shape of his nails?" If you are interested, you may wish to check it yourself. At that time, in order to prevent immigrants from escaping, officers and men tied them up behind their backs, then connected them with long ropes and escorted them to the road. People look back step by step, and the adults look at the big locust tree and tell the children, "This is our hometown, this is our hometown." Today, descendants of immigrants say that the ancient pagoda is their hometown, no matter where they live. Because the immigrant's arm was tied for a long time, his arm became numb and he soon got used to it. Later, most immigrants liked to walk with their hands behind their backs, and their descendants also followed this habit. On the way to escort, because of the long distance, people often have to pee, so they have to report to the officers and men: "Sir, please help yourself, I have to pee." The more times, the more simplified the verbal request. As long as you say "Sir, I want to relieve myself", everyone will understand that you have to pee. Since then, "jieshou" has become synonymous with peeing.

The questioner asked for authoritative basis. I can only say that the migration of Sophora japonica is a fact, and other stories derived from it have not been heard of scientific research so far!
