2. The school has no limit on what time to come back at night. According to the school regulations, the door under the dormitory 1 1 is closed, but some buildings are not locked for fear that some students will come back late. If you get along well with the aunt who is in charge of the dormitory below, you can knock at night, hehe, that's what I do.
3. The evening self-study school stipulates that all freshmen should attend evening self-study in the first semester, and it is not mandatory in the future, but some colleges will continue to attend evening self-study next semester (liberation after sophomore year)
In addition to self-study in the evening, freshmen should have an early physical examination in the morning, which means you have to get up at 6 am and run out to sign. (That's good, provincial colleges and universities have been sleeping. )
As for the electricity fee, a dormitory sends 8 kwh electricity, and then pays it after use. At one time, electricity was 70 cents, and water was free. You can't use hot things and things like that in the dormitory. If you plug them in, it will trip (some dorms won't, depending on your luck).
I wish you a happy stay at Agricultural University!
