If you are not a student of Tongji University, you are not allowed to live in the dormitory on campus. Unless you know acquaintances or friends to provide you with accommodation, you should be able to sneak into the dormitory. First, it must be managed through the aunt's dormitory, so it is not easy to mix up.

The cadre training building does provide accommodation for foreigners. I remember that in the past, the North Building of the cadre training building was a relatively cheap guest house, with three rooms and a bed in 45 yuan every day. I wonder if there is any price increase now. There is a standard room in the south building of the cadre training building, but the standard is higher. I guess you are a student and won't live like that, but you can ask.

Walk from the gate of Chifeng Road to Quyang No.2 Middle School for 5- 10 minutes.

There is a guest house on Chifeng Road, next to Xinya Dabao. I don't remember the name. The standard room is about 150.
