If it is a general express delivery, such as Shentong, Tong Yuan, Zhongtong and Dayun, you don't need to write the specific address. Just write the main campus of Tianjin Normal University, No.393, Extension Line of Binshui West Road, Xiqing District, Tianjin, with the zip code of 300384, and then write XXX to get it, because they are all notified by phone or SMS to pick up the courier, as long as the mobile phone number is written correctly. If you use EMS, you'd better write down the floor number, because the express delivery of the school post office is stored in different floors.
