Take the 102 bus from the railway station (not too far) and get off at Jiang 'an Primary School (also called Xinlitun). Jiang 'an Primary School is across the street. You can look at the specific location first. Then you walk in the direction where you came (that is, to the east), and you will see a signal light in a few minutes. There are many small restaurants and many clean restaurants in the east and north of that intersection, and there are hotels nearby, so your lunch and dinner can be easily solved.
If you want to go to Qiqihar University, you can see the bus stop on the north side of the intersection just mentioned. There is a 104 bus, which can take you directly to Qiqihar University.
