The apartment in South School is a big bedroom for 12 people, with three separate rooms, four separate bathrooms and a large bathroom.
The ordinary dormitory in the North School is one room for 8 people, with separate bathrooms, but it is very convenient and close to all places, such as canteens, public toilets, playgrounds, classrooms, libraries and so on.
The ordinary dormitory in South School is very complicated. I'm not sure about the details, because I'm from North School.
What's more, you said that "the dormitory is still short of water and electricity, so it is inconvenient for students to carry water upstairs and take a shower." This situation has been solved, no longer exists, and it is very convenient now. As for what can't be spicy, there is a special window for non-spicy, and you can also cook and don't eat Chili. It is about 1 hour drive from Changsha city. The traffic is convenient and there are many cars, so don't worry about not having a car.
