A total of 39 venues will be used for the Beijing 2022 Olympic and Paralympic Winter Games, including 12 competition venues. The venues have been divided into three clusters: Beijing, Yanqing, and Zhangjiakou.

Each cluster has its own athlete village. Of the 12 competition venues, six are in Beijing, two in Yanqing, and four in Zhangjiakou.

Beijing's downtown area will mainly host ice sports. Yanqing, the mountainous suburb of Beijing, will hold alpine skiing and the sliding events of bobsled, luge, and skeleton. Zhangjiakou in neighboring Hebei province will co-host snowboarding and ski events, including freestyle, cross-country, ski jumping, and biathlon.

"Tens of thousands of Winter Olympics constructors have devoted themselves to working according to the requirements of the construction of Winter Olympics since March 31, 2017," said Ding Jianming, deputy director of Beijing Major Projects Construction Headquarters Office.
