There is a bus stop called Qiao 'an Apartment. The road to the west of this station is Qilian Mountain Road. It's two or three kilometers to Zaozhuang Vocational College. At the intersection of Qilian Mountain Road and Guangming Avenue, there is a tall sign that says Zaozhuang Vocational College, which is very obvious. You'll know it's Qilian Mountain Road when you see it. It is not easy to take a bus at that intersection. Because of the exam, I suggest you take a taxi from where you live.
Guangming Garden Station is in the east and expressway is in the west. There seems to be accommodation on a north-south road in the middle, and the price is not clear. It's near Qilian Mountain Road.
