You should take bus No.51from Hainan University of Economics and Business and get off at Hainan Provincial Library.

You want to go to the back door of Haijing: after getting off, cross the road and turn right (that is, the direction of Haifu overpass). Walk about 30 meters, and you will see the bridge across the Meishe River. Don't cross the bridge Turn left and walk along the river. If you see the fire brigade, you will find it.

Haijing's back door is directly opposite the fire brigade! !
