The official print shop of Beihang University is located on the south side of Beihang Gymnasium, near the south gate of Beihang University, only about ten meters. It is very easy to recognize, because this is an iron house painted blue, which is called "blue house". There are many print shops in Beihang University, but only one is officially designated. The so-called official, that is, many things of Beihang University's educational administration are designated to type here. For example, the test paper that the course teacher needs to print is probably not only convenient for reimbursement, but also for safety reasons. Of course, there are many related functions. But for students, there are not many opportunities to contact this place, because ordinary printing can be done in ordinary printing shops. There are only two places that really need to communicate with them. One is the printing of graduation thesis, which must be printed at a fixed point here. Some colleges will deposit a sum of money here for students to print. The other is the purchase of real questions for graduate courses. Here, it is very useful to provide real questions for comrades who are preparing for the postgraduate entrance examination in the past three years. Let's pay a few dollars.
