Dude, China recognize Yuan Dynasty as a Chinese dynasty.
Ditto Qing Dynasty.

If neither were considered Chinese, then China can't claim Tibet as historically belong to them.

We can't argue with wumao 🤣

Sometimes they say Mongolians were Chinese. Because Mongolians conquered Tibet and Xinjiang, these two regions must be inseparable parts of China.

But when we talked about war crimes committed by the Mongolian army, they suddenly change their tone and say, "Mongolians were not Chinese."
