Thousands of years of China, with a long history, Yanhuang's descendants are endless.
The Yandi and Yellow Emperors are the roots of the Chinese, and today, we are legally recognized as Chinese and legally rational. Conquest in ancient times was more brutal, and the inhabitants of defeated countries and tribes were naturally included in the demographic composition of the victorious countries.
So did Genghis Khan Chinese?

He conquered vast areas, defeated other countries, and established the Great Mongol Empire, but in terms of roots, Genghis Khan was not a Chinese, he was not our Chinese descendants, and for the Chinese at that time, Genghis Khan was a barbarian and a foreign enemy who needed to be united and defended.
And we start from the Xia Shang Zhou, the Spring and Autumn and the Warring States, to the end of the Tang, Song, Yuan, Ming, and Qing dynasties, the roots of China have never changed, even if the later foreigners invaded the Central Plains and unified China, but the roots of Chinese civilization were not blocked, but silently absorbed and integrated one ethnic minority intruder after another, and finally many invading tribes and nationalities were incorporated into the Chinese civilization system, and everyone who had been the descendants of the invaders was born in Si and grew up in Si, and their roots were on this land, of course, they should be called Chinese!
The story of Genghis Khan we all know that he was an eagle on the steppe, a sweat horse on the steppe, and a hero gifted by that era.
His exploits.
1. Created the Mongol Empire, the largest territory in the world
2. Established the world's earliest transportation liaison system
3. Push military art to the highest peak of the era of cold weapons
4. The first emperor to practice political democracy
5. Pursue the policy of the freedom of religious belief
6. The first to put forward and practice "globalization"
Genghis Khan was born in the north of the desert, when the Mongol tribes were not really included in the rule of the Song or Liao and Jin, and until his descendant Kublai Khan established the Yuan Dynasty, Kublai Khan was called "Yuan Taizu", we can say that he was the emperor of the Central Plains Dynasty, of course, can also be regarded as the Chinese. Many people think that Genghis Khan is Kublai Khan's grandfather, and think that it is natural to classify him as a Chinese, which is a bit of a sense of self-deception, can not blindly follow the will of the public, unrequited thinking that Genghis Khan is Chinese.
The founder of the Yuan Empire was not Genghis Khan, and Genghis Khan did not become the emperor of China, so Genghis Khan was a fake Mongol.
In the spring of the second year of the Song Dynasty, the Mongol nobles held a meeting at the source of the Nan River, and "Genghis Khan" was recognized by the various kings and other Mongols.
But in fact, before the late Qing Dynasty, there was no record of the title "Genghis Khan" in the collection of Chinese literature and history in the Yuan, Ming and early Qing dynasties.
Many people think that he is a hero, and that classifying such a brave man as a Chinese can increase the pride of the nation, so many people have always thought that he is Chinese.
Where are the descendants of Genghis Khan today? Do they admit that they are Chinese?
It is rumored that there are now more than 16 million descendants of Genghis Khan, who are mainly distributed in Europe and Asia (Mongolia, Afghanistan, Russia, Iran and other countries) and the western region of China. The main surname of the descendants is the Boer only Jin clan (Mongolian royal family name), in China there are also Yu, Yu, Yu, Jin and other surnames distributed, no matter what the surname is, in China, of course, you can proudly declare that you are a dignified Chinese.
