[Shang-Chi, MCU & Marvel Comics] Spoilers (maybe): Ten Rings through History

It's not 100% clear in the film, but based on the opening showdown (Wenwu vs some Central Asian or Turkic citadel) and a throwaway line (something something >!["they've known me by many names" something "the great Khan"]!< something)... are we to understand that >![Shang-Chi's dad is actually Genghis Khan]!<? 

And if not, then which Khan was he? Is he Mongolian and not Chinese? How did he get called "Khan"?

Did the comics ever address this?

In the comics, originally, Shang-Chi’s dad was Fu Manchu which has been retired for being racist AF. Manchu was an immortal sorcerer in the 616. Manchu has also been renamed Zheng Zu to be less fraught. He was born in the 18th century, so was not a Khan from the Mongolia. 



Completely separate character from the Iron Man villain The Mandarin, who discovered the ten rings in an alien ship, and broke bad. Very different ten rings, at that. 

Xu Wenwu may have been Kublai Khan. Or it may have just been a title. Genghis was not the birth name and was a title. Temujin was the birth name of the man who would become Genghis Khan.
