Zhongzhu Building is 4-500m away from the entrance and exit. After passing the customs, go two blocks ahead (north). On the west side (left hand side), there is a dessert shop on the first floor. But you have to check the bus time in Zhuhai first. It seems to leave on the hour, and the whole journey takes 50 minutes. Take a taxi about 100- 120 yuan. I suggest that you must clear the customs before 3 o'clock.
