Hmmm, perhaps Shang's father will be replaced by the Mandarin? As some of you may have heard, Kevin Feige mentioned something interesting during an interview on Reddit. The article comes from here

So we know the Mandarin is coming back. And some fans have speculated (just speculated) that the Mandarin will be revealed as Shang-Chi's father. Now we've talked about this before and stated how there should be a difference between the Mandarin and Zheng Zu. Hell, I was one of those that said there should be a difference. The more I think about it though, hey, it could work. I think it could work mainly because the changes are superficial. I'm willing to bet he'll still be a long lived, nigh immortal Chinese bad guy who has been craftily manipulating events behind the scenes. The character will still be Zheng Zu, just packing the ten rings and called "The Mandarin." I'm honestly hoping that he becomes one of the main bad guys in the MCU moving forward.
In terms of comics, I think it's pretty easy for Zheng Zu to become the new Mandarin. The old Mandarin is dead, right? So Zheng Zu just finds the old Mandarin's rings, becomes the new Mandarin, and continues to want to take over the world. Easy.
Again, this is all speculation. Who knows, the Mandarin and the Ten Rings could become the latest bad guy in the Winter Soldier/Falcon series? So, as usual just playing with potential ideas here.
