All three Athletes' Villages have opened. Two are in Beijing, and one in the co-host city of Zhangjiakou in neighboring Hebei Province. On Thursday, the facilities welcomed more than 360 people from twenty delegations, including those from China, Italy, Switzerland and Canada. The villages are under what organizers call a closed-loop management system, to prevent the spread of COVID. CGTN's reporter Ning Hong has more details in the city of Zhangjiakou in Hebei Province. Zhangjiakou is one of the three competition zones of the Games.
