Highlights: The Capital Gymnasium is located on Baishiqiao Road and is a public institution directly under the State Sports General Administration in Beijing. The infrastructure in the Capital Gymnasium was rebuilt with reference to international standards. The roof is covered with colored steel plates with a span of 60 meters, and the light illuminance reaches 2000Lx (the international standard is 1500Lx). On both sides of the venue, two large color screens of 100 square meters are particularly eye-catching, with 6,900 beam spots per square meter to make the image restoration effect clearer. The stadium has one competition hall, three practice halls and six spectator lounges. The competition field of the competition hall is 88 meters long and 40 meters wide. The floor in the competition field can be moved and removed, and after the water is frozen, ice skating, ice hockey, figure skating and other ice sports competitions can be held.
