Kunshan Gymnasium is about 235,000 m3, with a 40-meter× 70-meter competition hall in the infield, which can accommodate nearly 6,000 spectators. There are fixed stands on three sides and a stage area on one side. During sports competitions, the movable curtain wall at the entrance of the platform is closed, and the stage area becomes an independent training hall. The museum is a multifunctional, comprehensive, energy-saving and modern indoor museum, which can not only hold international and domestic individual sports competitions, but also carry out large-scale comprehensive cultural performances, mass gatherings, cultural entertainment, national fitness, trade exhibitions and other activities. So far, Hong Kong and Taiwan singers Jacky Cheung, Jay Chou and Cai Qin have all held concerts in the gymnasium, and all of them have achieved good box office.
