Northwest University for Nationalities now has two departments, one in Yuzhong and the other in Lanzhou. I wonder which department your girlfriend is in? If you are in Yuzhong, everything is very cheap. There are many hostels at the school gate, and the price is between 10-20 yuan. The environment is ok. The food is also very cheap, much lower than Lanzhou. If you are in this department, you can stay in a hotel with relatively high grade and acceptable price nearby, which is very close to the school. Welcome to Lanzhou, welcome to Northwest University for Nationalities!
