Hello, classmates, there are no water heaters and drinking fountains in Room 6 and Room 4 of Polytechnic University. But you can rent the school water dispenser, and then you can ask the aunt in charge downstairs. If you want to pay a deposit, you can share it with your roommate. Of course, the water in Polytechnic University is free, and the school has three places to draw water, which is quite convenient, but this kind of water is not good to drink. There must be no water heater, hehe, I haven't seen it here for four years, unless it's a teacher's apartment.
