Why is the little toenail with two petals?

The characteristic of little toe is that the toenail of little toe is divided into two parts, the outer part is small and the inner part is big. Some people have thick and incomplete little toenails. There are two types of human little toenails, one is composed of two petals, that is, there is a crack on the toenail, which is called double petal type, and the other is composed of a complete toenail, that is, there is no crack on the toenail, which is called single petal type. Double valve type is dominant and single valve type is recessive. This kind of multi-toed little toe is widely distributed in East Asia, and it appears most frequently in the Han population. Folklore is a symbol of Sophora japonica in Shanxi. On the internet, it is said that the compound toe comes from Huns, Qiang people since ancient times and Manchu people. Anyway, I said everything. The compound toe of the little toe is not deformed because it has no dysfunction. The compound toe of the little toe also has the characteristics of delay. Some people don't show it when they are young, but they develop obviously in adulthood. Han people are divided and combined, and the south is less than the north. Other ethnic groups are divided and undifferentiated. Looking up the ancient and modern materials of China, from the period of the Yellow Emperor to the early years of the Tang Dynasty, there is no record that Han people have double toes. Well-known Confucianism has long been the dominant ideology in China society, and Confucianism attaches great importance to its own health. Don't throw away your hair, nails, beard and other parts, and there is no record of "abnormal phenomenon" of little toe cover. Answer with a sentence in the Book of Filial Piety, that is: the body is damaged, parents are afraid of damage, and filial piety begins. Imagine if people found their little toe cap "cracked". It really doesn't make sense without a book to prove it. Then there is only one reason-at that time, the little toe cover of the Han people was complete. The first person in the Han nationality who discovered that he had double toes was Emperor Taizong. He was annoyed when he found this phenomenon. He once sent a secret order to check everyone's little toes in the palace. As a result, he was surprised. It turns out that not only he, but almost half of the people in the harem have double toes. These people are Xianbei people. So where did Li Shimin's compound toes come from? Of course, this comes from his three mothers, because Li Shimin's mother is also a Xianbei person. It turns out that the little toe cover of Xianbei people is forked. Xianbei people originated in Daxinganling. Around the 4th century A.D., Xianbei moved south to the Central Plains, and established the regimes of Houyan, Xiyan, Southern Yan, Xiqin, Nanliang, Northern Wei, Eastern Wei, Western Wei, Northern Qi and Northern Zhou in northern China. The ruling class of Xixia also came from Xianbei, which is the largest minority in China's history. Qidan is a branch of Xianbei. The Khitans once established the Great Liao State, with an unprecedented territory. The Khitans established the Western Liao Dynasty in Central Asia. The Khitans further introduced toe genes into other ethnic groups. Xianbei people were mostly integrated into the Han nationality during the Southern and Northern Dynasties in China, and at the same time, they brought the tiptoe gene into the Han nationality. Xianbei people who are integrated into other ethnic groups bring their toes into other ethnic groups. After several generations of reproduction, in the Song Dynasty, toe duplication of Han people in the north increased sharply, while most Han people in the south immigrated from the Central Plains to escape the war, and Xianbei people rarely joined, so toe duplication was of course rare. So that in the Ming dynasty, people thought that tiptoe was a patent of the Han nationality. Zhu Yuanzhang, the founder of Zoroastrianism, once ordered that "anyone whose little toe cover is not split is a Mongolian and should be killed". At that time, I didn't know how many Han people were killed by mistake. The legend of "big pagoda tree" originated in the Ming Dynasty. In fact, the Han people near the pagoda tree are not authentic Han people, but highly degraded Han people. So people who come out of the "big locust tree" are all double toes. After dynasties, wars, immigration. Previously, the Han people who went south from the Central Plains without toes were not considered authentic, but the "Han people with toes" who were incorporated into Xianbei became authentic, which is actually a "Central Plains plot" of China people. In the Qing Dynasty, people from the Central Plains immigrated to Shanhaiguan, commonly known as going to Guandong. Most of the Han people and Saman people who went to Shanhaiguan came to Shanhaiguan with Xianbei compound toes. So what was the little toe of Manchu outside the customs at that time? Manchu is the descendant of Nuzhen of Sushen Department, and Nuzhen has no toe duplication, which means that the authentic little toe cover of Manchu is complete. Incomplete also comes from Xianbei. Mongolians also have double toes, because they come from Xianbei. The situation of toe duplication of ethnic minorities in southern China is unknown. Attachment: The legend of Sophora japonica, also known as "Tong", is located 2 kilometers northwest of Hongtong County. This ancient tree with thick trunk, withered branches and ravines is the ancient pagoda tree. "Ask me where my ancestors came from, Shanxi Hong Tong Sophora japonica. What's the name of your ancestral home? The old nest under the big locust tree. " For hundreds of years, this folk song has been widely circulated in China, and is well known to women and children. If we want to trace the source, we have to start from the last years of the Yuan Dynasty. At the end of the Yuan Dynasty, floods and famines occurred frequently in the Huanghuai Valley, ethnic conflicts intensified, and the Red Scarf Army uprising broke out. The Yuan government brutally suppressed and fought fiercely for more than ten years. People in Huaibei, Shandong, Hebei, Henan and other places were killed 10, and the originally prosperous places became impassable and deserted. The tug-of-war of "Jingnan Battle" in the early Ming Dynasty was even worse, and many places were deserted. Different from the neighboring provinces of the Central Plains, Shanxi, as the hinterland of the central part under the rule of the Yuan Dynasty government, has no natural and man-made disasters, favorable weather and prosperous economy, which makes the population here prosperous. Coupled with the settlement of a large number of refugees, Shanxi, especially southern Shanxi, has become a densely populated area. In order to develop the economy and consolidate the political power, during the fifteen years from Hongwu to Yongle in the early Ming Dynasty, the Ming government organized and implemented eight large-scale immigration activities for more than fifty years. There used to be a temple here-Guangji Temple, which was built in the second year of Zhenguan in Tang Dynasty (AD 628). The temples are large in scale, magnificent in halls, full of monks and pilgrims. There is a "tree surrounded by several acres of shade" next to the temple, and the old people on Fenhe Beach build their nests in the tree, which is very spectacular. Under the tree, the avenue of chariots and horses crosses, and pedestrians in all directions are in an endless stream, which is the traffic hub. Because Hongdong is located in the densely populated center, the terrain is open and extending in all directions, which is convenient for centralized immigration. The Ming government set up a bureau in Guangji Temple to specialize in immigration affairs, and the pagoda tree became a gathering place for immigrants. Immigrants are mainly distributed in Henan, Hebei, Shandong, Beijing, Jiangsu, Anhui, Hubei and Hunan, and a few have moved to northern Shaanxi, Shaanxi, Gansu and Ningxia. These immigrants later moved to Yunnan, Sichuan, Guizhou, Xinjiang, Northeast China and other places. For such a long time, the people of one side were scattered in various places in an organized and large scale, which is unique in the history of China. At that time, it was here that the immigrants began their journey after accepting the "Zhao Zhao Chuan Zi". When they left, the immigrants turned their memories into memories and looked back frequently. In the end, they only saw the big locust tree and the old man's nest, which became a symbol for the immigrants to bid farewell to their homeland. As time goes by, people can't remember whether they moved here from He Cun, but that big pagoda tree is deeply rooted in the hearts of generations. According to ancestors, all close relatives of the same family moved to the big pagoda tree in Hongtong. Brother Niu smashed a cauldron when he moved, and each of them took a piece of broken iron as a souvenir, so he was called "beating the pot cow". Hebei, Henan and other places also have the legend of beating a pot of cattle. People want to hug for the last time before leaving because of their nostalgia for the big locust tree. There is a family of eleven brothers who are hard to get through hand in hand, and it was finally realized after the eldest sister-in-law joined. Therefore, it is conceivable how big the locust tree is. It is said that in order to prevent escape, every officer and soldier registered one. They asked immigrants to take off their shoes and cut a knife on their little toes as a sign. Therefore, until today, all the little toenails on the feet of the descendants of immigrants from Hu Aixiang have two petals. "Mo Daoyuan has no textual research, and the private account is the most true." "So, the old legend tells anecdotes and asks you how to point to the fruit?" If you are interested, you might as well check it yourself. In the process of migration in some counties of Shandong, Shaanxi and Henan, officers and men often use the form of binding to prevent people from escaping on the way, and then connect them with a long rope and escort them to the road. Because of the long distance and time, carrying hands has become a habit. Most immigrants still like to walk with their hands behind their backs, and their descendants also follow the habit of factories. Also, the commonly used word "boundary head" comes from immigrants. It is said that during the long journey, when people need convenience, they should report to the officers and men: "Sir, please relieve yourself, I have to pee." The more times, the simpler the language. Just say "Sir, I'll stop here" and both parties will understand what it means. Since then, jieshou has become a noun with a specific meaning. After immigrants move into their new homes, they plant locust trees in front of them to remember their homesickness. Some immigrants named villages after their original places, such as Zhao Chengying, Zhou Pu Camp, Changzi Camp and Hong Tong Camp in the suburbs of Beijing, which explained their migration places in those years. Many genealogical inscriptions handed down to this day also record the process of migration. These are all historical witnesses of immigrants leaving their homes in those years.
