Photo taken on June 12 shows the National Aquatics Center, otherwise known as the "Water Cube", which will be transformed to host curling events at the Beijing Winter Olympic Games in 2022. Chinese experts have been working on key technical issues related to transforming the venue originally designed for water games into a stadium for winter sports, and have already upgraded the dehumidification, sound and lighting systems, as well as mechanical and electrical facilities, in order to reach the standard necessary for the curling event. After the Winter Games, the venue will be used as a site for ice sports, regular training and performances.
