There is a hotel in 50 yuan for one day.

Hotels in 50 yuan can be found in suburban villages, such as Jiangsan Village in Binjiang District, Lianzhuang, Xintang Road near the old East Bus Station and Xiangfu Bridge near the North Bus Station.

I suggest you find an Internet cafe to sleep for one night. 15 yuan can get it and play. The chair in the internet cafe is still very comfortable to sit on, and two chairs can sleep when sitting opposite each other.
