It is said that the dormitory of Peking University will be completely cut off at eleven o'clock every night, so it is not convenient to study at school all night, but there is still room for a closer look. Never go to the six restricted areas of Peking University alone at night, or you will see unexpected things. The six restricted areas are: classroom 609 of the Five Teachers' College, water room on the first floor of dormitory 58, sun room in the backyard of the old biological building, classroom 1 15 of the Six Teachers' College, corridor of the old library building, and the third computer room of the most horrible computing center.
The 609 classroom in five teaching departments is also called the study room for fifteen people. The teaching department was called Martyrs Building a long time ago. This is because there are always one or two dead-headed students jumping off buildings here every year. At that time, the sixth teaching department had not been built. Except for the inexplicable tower, the Fifth Teaching Department was the tallest building on the campus of Peking University at that time. Now, let's talk about Room 609. There are five teaching departments on the sixth floor 10 classrooms, and the four in the south are even numbers from 602 to 66544.
