1. Lanzhou is located in Gansu Province. As an industrial city, its heavy industry is relatively developed. Due to the long and narrow east-west direction and mountainous terrain on both sides of the north and south, the air here is not easy to circulate, so the pollution is more serious. Students studying here will naturally find it difficult to adapt.
2. The economy of Gansu Province is underdeveloped, and the area of Lanzhou Jiaotong University is relatively small, and the infrastructure may be worse, such as old dormitory, poor environment, small playground area and imperfect equipment.
