Where is the ladder classroom 3 of Ningbo University? How to get in from the east gate?

Go straight to an intersection (Anzhong Building on the left) and there is a path on the right. When you walk in, you will see two buildings, one is Huangchen Yueli Building, and the other is the campus 1 10. If you point forward, you will go to another road, cross that road and you will see the library. Go straight ahead and there is a door (the side door of Building 4). Go straight in.
