Khublai was not an emperor of China, he just conquered China

Khublai Khan, one of the Mongolian great ancestors, had never been a Chinese, he was a Mongolian Great Emperor. His biggest mistake during his rule over Mongol China was that he moved the Mongolian capital city from Khar Khorin to Beijing (because at that time the territory of China was Mongolian territory). Because of this, Chinese think and like to talk that Khubilai was their King, but this is a huge misunderstanding, Khubilai was just ruling them.
