First of all, I saw it on the 28th floor. This is a four-story dormitory building with the door facing east. Some dormitories on the lower floors have been completely emptied. Its internal structure is that there are two bunks on one side of the dormitory, four beds in total, the odd number is the lower berth and the even number is the upper berth; On the other side, there are four groups of desks (computer desks) side by side-each computer desk has two groups of desks, with a keyboard that can be pulled in and out, and a drawer. The bookshelf on the wall is connected with the desk, and there are two floors, each with a height of 40-50 cm. There is a locker at the top of the bookshelf, which is about 50-70cm deep and covers an area of nearly 1 m2. There is an open space (or corridor) between the bunk bed and the desk, which is about 2 meters wide and the dormitory is about 8~ 1 1 meter deep. The low-rise dormitory was installed with iron fence and painted with dark green paint. The dormitory is well lit, mostly east-west.

The walls of the dormitory are newly painted and the furniture is new. Outside the dormitory, the towering ginkgo trees are flourishing. In the breeze, the leaves fluttered and made a loud noise. In summer, the dormitory on the 28th floor is cool because of the shade. In winter, the leaves are falling, the sun is shining and the dormitory is warm. It's warm in winter and cool in summer. Because some undergraduates now live on the 28th floor, they see that the security of the building is very strict, and they need a key card to get in and out before they can pass through the access control system. The building manager's office is on the inside of the building door, guarding the main road in and out.

I walked out of the 28th floor and passed by the 29th floor. As the 29th floor is a girl's dormitory, I didn't go into the building to know the situation. The 29th floor is also located in the center of Yanyuan Garden, with the overall east-west direction and the north-south direction of the dormitory, to the west of the 28th floor, to the east of the 3 1 building and directly opposite to the 30th floor. Among the four most legendary dormitory buildings in Peking University, there are the prestigious sculptures of science and democracy in Peking University. As we all know, "scientific democracy is unproven, but it is actually the motto of Peking University". Every morning when I wake up from my dream, I can see the sign of "scientific democracy" through the windows on the 28th and 29th floors. For Peking University students, a sense of mission and self-motivation arises spontaneously.

Then go through the 35th floor, the canteen and the 44th floor, and directly reach the 45th floor, 46th floor, 47th floor and 48th floor of Peking University, which are the most concerned. Here, I see all the dormitory buildings have been replaced with brand-new white plastic steel doors and windows, shining in the sun. The 45th to 48th floors are all of the same structure, so I randomly selected Unit 2, 46th floor, Peking University Student Dormitory. In the corridor on the first floor, two kind and dignified building directors are checking the facilities in place one by one.

Then, I visited the dormitory. When talking about the dormitory house number, the building manager gave an authoritative explanation: the meaning of the four-digit house number is that the first place is the unit number-45 ~ 48 floors are all three units on each floor; The 2nd and 3rd digits are layer numbers, the first layer is 0 1 02, the second layer is 03,04, ..., and the sixth layer is 1 1,12; The last digit is the room number, the left-hand side (west) of the building is a double number, and the right-hand side is a single number. When talking about network facilities, the building management pointed out that each dormitory will have two internet access ports, so students living on the 45th floor to the 48th floor need to prepare their own hub if everyone has internet access needs.
