Seems to be some travel headaches for winter Olympic athletes. Since the global crisis, flights to and from China have dwindled making it a a challenge for people to get to the events.
Further, and complicated this year due to the crisis, are the challenges to host such a mega event.
One good thing is that vaccines are required or face a 21 day "layover."
Oh yeah, be sure to watch Curling (photo from 2018, Vegas men's world Championship).
