Who said Genghis Khan was not from China? I laugh at who and that every day.

Only Koreans say Confucius is Korean.

Only people in China say that Khan is from China.

Cheng Khan, mentioned in the history of the world, has always been the Khan of the Mongolian Empire, and has never been the emperor of China.

If Cheng Khan is from China, then Mongolia should treat him as a foreigner?

First of all, Cheng Khan never ruled China. Second, even if the later Mongolian Empire occupied China, then Cheng Khan was not a native of China.

Because the Mongolian empire occupied too many countries, which occupied country should Cheng Khan be?

The Japanese also occupied half of the country-China, and established rule. So Hirohito is also from China?

Vietnamese never said that Qin Shihuang was Vietnamese.

Mongolians never say that Chiang Kai-shek is the president of Mongolia.

How did you become China in Cheng Han?
