The accommodation environment in Hongqiao Campus of Polytechnic University is very poor, with 8 people living. There is no toilet and toilet in the dormitory, and there is a public toilet on each floor. You have to go out and take a bath, it seems to be only 500. Because the accommodation environment of most schools in Nanjing is similar, such as Nanyi and Hongqiao Campus, where there are few people, only three colleges have graduate students, and doctoral students are in Dingjiaqiao Campus, where the environment is similar and close to Hongqiao. It seems that big 1 liter, big 2 changes dormitory and has to run all over the street.
