Is China ready to host the Winter Olympics?

Over the course of 19 days, more than 3,000 athletes and thousands of trainers and support staff, as well as media and spectators are expected to converge on Beijing and neighboring Hebei province where events will be held. All participants will be inside a “closed loop,” with tighter restrictions than those seen at the Tokyo Summer Olympics. Volunteers began entering the closed loop this week, where they will stay until the end of the event.
