Generally, a six-person university room is more common, with only two lower bunks, and the rest are upper bunks, including a bathroom and a washroom (two swimming pool faucets, a mirror, and a place to put daily necessities). Everyone has an iron cook, and there are two big tables in the dormitory, one for three people, which can put books and other supplies.
The quadruple room where I lived in my freshman year was originally for graduate students, all of which were upper bunks. Below is my own big desk, which can hold many things such as computers, and even lie on it. O(∩_∩)O~ The bathroom is the same as a six-person room.
But there is no small bathroom between the eight rooms in our old school and the eight rooms in my classmate's school. Like high school, the whole floor shares two large bathrooms, and the room is crowded and messy, but there will definitely be an iron cook, which is reassuring.
Of course, my understanding is not very comprehensive, but it would be best if eight people can bring their own bathrooms, and nothing else is required.
