I know some of you guys often visit to the Pusan National University. Maybe someone already study there. first of all, sorry for write here. The reason i wrote here is i don't know where to post about this subject.
I'm here to introduce the website(or android app) that could help you guys a lot. It is called 'pnumap' which you can use when you find certain building in PNU. it will show you a picture and the information of the building that you looking for. I believe it could be very useful for the foreign students who came to PNU recently. Thanks
