I have a certain right to interpret whether I choose the upper berth or the lower berth as a freshman, because I have lived in the upper berth and the lower berth in college. ? First of all, I have lived in the upper bunk since I was a freshman and a junior. Because I was used to living in the upper bunk when I was in high school, what I want to say here is that if some students like the upper bunk, they can stay in the upper bunk. After all, they are used to living in the upper bunk. I suggest some students love cleanliness, because when living in the lower bunk, there are probably some students lying in your own bed. So at this time, you must choose a shop with an upper berth. Generally, no one goes to the lower berth of your bed. You may let others do it in your bed or sleep. After all, there are many people, and they are usually used as stools, the same size. So at that time, considering this, I chose the upper berth. It's relatively clean, because usually only one person goes up to rest, and others don't want to go to the upper berth, so she goes. Therefore, for students who love cleanliness, it is best to choose the upper berth, otherwise they will not be used to the lower berth. But students like convenience in their hearts, so they must choose the lower berth, and I will live in the lower berth. Later, I found that sleeping in the lower berth was really comfortable. At least the space of the lower berth is relatively larger than that of the shops, because the lower berth is more convenient, whether at noon or at night. I didn't know I had to take off my shoes every time I went to the upper bunk. When I get to the lower berth, I will lie on it and put my feet on the ground, which is very convenient. And after the lower berth, it is also very convenient for us to buy bed curtains. Unlike in the upper bunk, we have to use wire to draw a curtain shape in the lower bunk and hang it directly on the main shaft of the bed.
