As early as 2005, Professor Bian Jianchao of Fudan University made a genetic statistical analysis and found that the proportion of cracked toenails gradually decreased from north to south. However, this data does not support the view that "cracked toenails are pure Han people".
The follow-up study counted 2980 Han people and 72 1 Uygur people. The statistical results show that 58.97% of Han people and 5 1. 15% of Uighurs have the characteristics of cracked toenails, which means that cracked toenails have nothing to do with whether they are Han people or not.
There is no scientific statement of pure Han people. We are not a country across the ocean. They like to distinguish people according to their ancestry. We mainly divide ethnic groups according to cultural identity, and even have no habit of pure blood for animals. Our ancestors lived in the Central Plains with a pleasant climate and derived advanced cultural etiquette, so they called the tribes with backward surrounding culture barbarians.
The core of the difference between China and Yidi is that Yidi agrees with our culture just like us. It can be seen that our ancients did not say anything about lineage.
Confucius wrote "Spring and Autumn Annals", saying, "When Yidi entered China, it was China's, and when China entered Yidi, it was Yidi's". It is believed that as long as you accept the Central Plains culture and Chinese civilization, you are from China, no matter what race or origin you are. This is essentially the difference between civilized people and barbarians.
Han Yu's The Original Way: Confucius' Spring and Autumn Annals also tells us that when a vassal uses foreign gifts, it is foreign, and when he enters China, it is China.
Han nationality and Han nationality are a big concept, which is formed by the continuous integration of the Chinese nationality in the ancient Yellow River valley with people from other nationalities and regions for thousands of years. Therefore, the word "pure Han Chinese" has neither scientific reason nor cultural connotation.
We don't know who first discovered the phenomenon of little toe cracking, but the earliest record about whether little toe cracking is related to bloodline is Li Shimin of Emperor Taizong. After all, he is the emperor, and his ideas are far easier to record and pass on than ordinary people. But the problem is that Li Shimin is a descendant of Xianbei people, so toe cracking is not a unique physiological phenomenon of Han nationality.
Some people say that the little toe has a cleft flap because many people cut the little toe's nails with a knife as a mark in order to facilitate future generations to find their ancestral roots before going through the migration procedures under the big pagoda tree in Hongdong, Shanxi Province in the Ming Dynasty. From then on, no matter where they moved, the offspring born can know that their ancestors came from the big locust tree in Hongdong, Shanxi Province according to the petals of the little toe. Such stories and legends can only be heard as short stories to pass the time, but they are actually against genetics. According to this logic, are Yang Guo's descendants all one-armed?
