Now is the place for self-study in summer vacation. It is estimated that only Xinhai Building will open from the north gate and you can see it on your right.

Simon, if you don't know whether to open the door now, of course you can go in. There is a Haiyun Hotel at the entrance of Taolin Road. If you go to the teaching building, it's near the east gate. If you go straight along the road, you can see it. As for the way, people are not all with one mouth. Just ask Haida, not much.
