There are many Tianma resettlement communities where I live now. I got off at Fubuhe (202, 905, 9 13, Dadui 1) in Golden Apple Community. You can see many signs that say family hotel along the road. Students live there and say it's ok, about 30 a night (it should be possible to bargain). Ten minutes' walk to Tianma apartment.
It's similar here at school, 30-80. The more expensive is the hotel at Tianma T-junction. I forget what it's called. It's a single room of 80, but the environmental sanitation is really better than others.
Then there is Tianmu Hotel (south of Tianma Apartment, the building of Computer City, etc. 180+), Tianma Hotel (at the intersection opposite Tianmu, walk down for about 5 minutes. 180 or so), Lushan Hotel near Dongfanghong Square (behind buildings such as Mathematics College, Physics College and Experimental Building). It's hard to describe. You can ask for directions when you arrive. The price is not much different from the first two).
Upstairs said it was in the school. . Never heard of it. If you are an art student, you can consult the school. Schools are definitely safer. It is a good choice to ask the teacher if he has a place to live. If you live permanently, you can consider sharing a house with others in the resettlement community and mining institute.
good luck
