None of these things can be used, which will be very inconvenient, but if you watch some news, you will find that it is right for the school to have such regulations.
A fire broke out in the female dormitory of a university in Shanghai. M-girls jumped from the sixth floor to escape and all died. The cause of the fire was that students illegally used the boiling water artifact in the dormitory. "Quick heating" is a very simple heating tool with very low safety factor. Coupled with shoddy construction and cutting corners, it is easy to cause safety accidents.
Many students are lucky. Accidents such as dormitory fires caused by illegal use of hot water or heaters happen almost every year.
High-power electrical appliances are restricted, on the one hand, because of load restrictions, on the other hand, for the safety of dormitory. University dormitories are densely populated and consume a lot of electricity. However, some universities were founded earlier, and dormitory buildings are likely to have security risks due to aging lines, which makes it difficult to bear excessive power load. Therefore, once a fire breaks out in the student dormitory, the consequences will be unimaginable. Therefore, for everyone's safety, schools generally take measures to limit electricity.
