Colleges and universities in Beijing are all public bathhouses, and there are two public toilets on each floor of the dormitory. I don't know if the teaching building you mentioned is newly built, but all of it? Universities generally have many teaching buildings, which can't all be newly built, especially those with a long history, both old and new. Actually, it depends on what you value If it's employment, don't worry. As far as the geological industry is concerned, a large area is the best. If you want to enjoy it, I suggest choosing another one. Looking around the universities in Beijing, I think they are actually not better than those outside Beijing. So it depends on what you value. I wonder if you are satisfied? If you have any questions, you can ask me. I am a big country (Beijing) and I know it better.
