Any restriction for chinese wifes father?

[ImagineMe 35]

My wife went back to China for a couple of months and is planning her return. I haven't been able to get reliable info through internet searches nor on here if her father can come back directly from China, or if they have to do a 2 week quarantine in a country not on the ban list. They want to come back in mid May. I've read that regular tourist visa holders cant come directly from a banned country. But does it also affect her father? She has a 2 year greencard and in the waiting process for the 10 yr greencard interview. And yes she has her extension letter.

He would need 2 weeks in Mexico wherever is convenient.

OK I was able to reread the presidential ban and decipher it. The language that first confused me was the parents thing but now realize that its for unmarried individuals under 21. For anyone else that may have this question here is the order highlighted.
