1. Generally, new buildings are dormitories for 6-8 people, and the two dormitories share a bathroom without a shower. There are also 6 to 8 people in the old dormitory, with a small number of 8 people. The first floor uses a large public toilet. If you have a campus network, you can also go to telecom to pull broadband yourself.
Freshmen generally don't give you a new building when they come in. Dormitory allocation seems to have little to do with any major. When to live in what dormitory depends on the arrangement of the school. For example, my junior year is almost over, and the school informed me to live in a new dormitory next semester. I have lived in my new dormitory for a year as a sophomore.
In addition, there seems to be no boys in the new building (but the conditions of boys' dormitory are much better than those of girls' old dormitory), but it is hard to say whether boys can live in a new dormitory. .
