If you want to go to Hohai University next to Suiyuan Campus of Nanjing Normal University, you can take bus No.36 to Huamu Company, one stop in front of Nanjing Railway Station. Where is the bus to the entrance of Hohai University? I don't remember the number. I took it. It comes from Hongshan Zoo. Or you can go to Heather Normal University with Jiacang. The west gate is connected with the river and the sea, across the road.
