BS is on the first floor. After studying for half a year, I can't even recognize the teaching building. I usually go to play. Usually, it seems that the all-night classroom of four teachers (Boxue Building) can go up to 1 1: 30 at the latest, and the ordinary classroom can go up to 10 or so. The library closes at 9: 40 pm, and Sanjiao (Yucai Building) can stay until 9: 50 pm. But the teaching building is closed in winter vacation.

From the north gate of Zhengqianyu North Campus, there are four religions, and the buildings on the west side of the lake are three religions. You can sit in any classroom inside, nobody cares, as long as there is no one in the classroom at that time.
