Books on law are on the east side of the third floor, as are books on management. There is a bulletin board in the lobby on the third floor, and study rooms on the fourth and seventh floors. There is also a study room on the eleventh floor, but it is rented by students. You must have a campus card of bohai university to enter the library, and punch in when you enter. Also, notice that you just entered the library hall on the second floor, not the first floor, so pay attention. What you don't know can be added.
