You stopped a rose-red "Shantou-Liusha" car in the direction of Shantou at Jinye Building, and said to get off at Xidi, probably in 7 yuan. There is a bus stop under a tree opposite Xidi Station Road. Take the No.25 2 yuan and get off at the Exhibition Center (Wal-Mart). After getting off the bus, ask where the library is. Because I am not familiar with Shantou, I have to go back the same way.
