There are many cars from Sanxiang to Gongbei. They are all from Zhongshan, via seven roads and three townships, to Zhuhai. You don't have to wait at Ping 'an Station. Waiting at any bus stop, you can see the words Gongbei waving. Ticket price, 8 yuan.

Personally, I like to take Sanxiang Bus No.605 (2 yuan) to Cai Hua Antique City, and then transfer to Zhuhai Bus No.31to Gongbei (air-conditioned 2.5 yuan

Not air-conditioned 1.5 yuan).
