Which bus should I take from Suzhou North Station to Cui Wen Student Apartment? Or which bus should I take from Dushu Lake Campus of Suda University to Suzhou South Station or North Station?

You mean North Bus Station and South Bus Station? Do you only have 180 ... 180 seems to be a newly opened loop? I haven't forgotten to take the bus for a long time, but you can sit in Xi Jiaotong University first. There is a bus to the bus station. You can take bus 16 to the south bus station and bus 178 to the north bus station (near the railway station).

If you mean the train station? The railway station is divided into North Station, Old Station and Park City Railway Station. The North Station is far away, and Dushu Lake needs to change trains to get there (Express Line 2 goes to the administrative center of the park first, and then transfers to 139). If the old station is near the North Bus Station mentioned above, just go directly to 178. The subway station in the park is relatively close, and you can get there at 1 15.
