Generally speaking, the best dormitory is a school dormitory with 4-8 people. Generally, student dormitories are divided by the school and cannot be changed. But when choosing a bed, you can pay attention to choosing the best position. If it is a bunk bed, you can choose the position on both sides of the window. Because of the good light, it is not as cold as the door in winter. If you are a student who likes cleanliness, you can choose the upper bunk to avoid other students sitting on your bed after coming. If you don't like tossing, it is more convenient to choose the lower berth, and it is also convenient to take things back and forth.
