2. generally not. But occasionally there will be a stall on Xishan Street at night, or there will be a flea market to sell at the beginning of school, graduation season or campus cultural festival, and some will go to bed to sell, but it is not recommended, and the aunt downstairs will not let me, and the students are also very disgusted.
Forget it, there are too many slopes and the campus is not big. A walk between classes is enough.
I suggest you use express delivery. Just write the address of Dalian University of Technology (if you live in Xishan, add "Xishan Living Area"). Usually you can pick it up in front of the building at noon. If you use EMS, it may be more troublesome. It is better to write all the dormitory addresses. The dormitory address I wrote last time was received by the college mailroom.
