Purchase tickets and join the fans at a game at Guangzhou Gymnasium. If there's nothing happening while you're there, you might like to check if they give a guided tour of the facilities.
This sporting facility is located in Baiyun District, a place that has lots going for it! Yuexiu Park, Museum of the Mausoleum of the Nanyue King, and Zhenhai Tower are other worthwhile attractions close by when you've finished up at Guangzhou Gymnasium.
