Shen Jin, deputy director, Beijing 2022 organizing committee's venue planning and construction department: We've designed plans for the reuse of all new venues prepared for Beijing 2022, and sustainability has been key throughout the whole process－from the planning phase to the Games themselves and the post-Olympic era. A lot of the Winter Olympic venues are built for highly technical and difficult sports that not everyone can try. Yet, we've planned thoroughly for each of the facilities and will turn them into multifunctional venues after the Olympics to cater to more activities, such as sightseeing, conferences and outdoor leisure activities.
