Don't let students stay on the first floor on the west side? No. The first floor is the social science lending library. Books borrowed by humanities are all on the first floor, and they are not only opened for a short time. They open at 8 am and close at 4: 30 pm, which is normal time. The first floor is social science lending, the second floor is natural science lending, the third floor is electrical and electronic lending (plus architecture), the fourth floor and above are all kinds of reading rooms, and the seventh floor is the study room. The stairs outside are part of the building. Don't you think there are high stairs outside the Great Hall of the People just to look solemn?
