The airport takes the subway to the downtown area (Tiyu West Road, the most prosperous area in Guangzhou) for 4 minutes. Six hours, high consumption, out of the sports center to Zhengjia Square, shopping, food, entertainment through train, or to Chigang, visit Xiaoman waist, the tallest building to enjoy the scenery of Guangzhou. (The same security requirements as airplanes).
The spending power is average. Go to changshou road subway station to visit Shangxiajiu Pedestrian Street, where Guangzhou cuisine is the most authentic. I recommend porridge and ginger milk, and Lianxianglou's snacks are good.
