During the 19th Asian Games in Hangzhou, the squash battle is held in the transparent "Crystal Palace," a specially-designed squash court located at Hangzhou Olympic Sports Center. The president of the World Squash Federation, Zena Wooldridge, has emphasized that the glass courts used in squash are a unique feature of the sport. These courts allow players to have a partial view of the surroundings, while spectators have a clearer view of the game. According to Wooldridge, squash is a sport that aligns well with modern lifestyles. It can be easily learned and played with the right equipment, and requires only a short amount of time. Playing squash also provides a good level of fitness, and allows for fun and tactical gameplay.
