In ancient history, the territory of Mongolia should have belonged to the territory of China, but during the Qing Dynasty, the Mongol Empire took advantage of the decline of the Qing Dynasty's power and gradually became independent with the help of Tsarist Russia, leaving the Qing Dynasty's sphere of influence, so the ownership of Genghis Khan became a problem.

Mongolia regarded Genghis Khan as a great hero and the creator of the Mongol Empire, and today statues of Genghis Khan are often seen all over Mongolia, and Genghis Khan occupies an important place in the minds of Mongolia until modern times, whether Genghis Khan was Chinese or Mongols has always been controversial.
Historians have their own opinions, and in the history of our country, Genghis Khan was once called the Emperor of the Ages, not only the Mongols, but also some other ethnic minorities, who all formed part of the Chinese nation. From the point of view of the place of birth and the area of activity, Genghis Khan was born in Mongolia and grew up in Mongolia, from which it is certain that Genghis Khan's ancestral home belongs to Mongolia.
Genghis Khan's descendants were active in China, and Kublai Khan occupied China, established the Yuan Dynasty, and posthumously recognized Genghis Khan as Yuan Taizu. In addition, the Manchu Qing dynasty once conquered Mongolia, conquered China after entering the customs, and now the Manchus can fully integrate into China, and the territory of that year should belong to China, so Genghis Khan should belong to China, and genghis Khan should belong to Mongolia just by relying on his birthplace, obviously no one is willing to recognize it.
All in all, the fact that Kublai Khan, the grandson of Genghis Khan, established the Yuan Dynasty in China is ironclad, indicating that the Yuan Dynasty belongs to China, so Kublai Khan must have Chinese. Historians today prefer to believe that Genghis Khan was Chinese, but he belonged to the Mongol ethnic group, and at least 18 million people around the world are descendants of Genghis Khan, but the descendants of the Golden Family are very rare. In the eyes of these descendants, the fact that has always remained unchanged is that Genghis Khan was a Chinese, not a Mongolian.
