I am a graduate student at Sipailou, and there are very few undergraduates here. The address can be written: No. 2, Sipailou, Nanjing City + department + major, your classmate’s name and phone number. Generally, each department will have someone assigned to pick up such letters from the mailroom, and then distribute them to everyone. Dormitories are usually located in the dormitory office downstairs. Both Qunying Building and Huihui Building of Dongda University have 14th floor.
