Welcome here ~ ~ The comprehensive building, a library and two study rooms are open in summer vacation. It is said that only the student ID card can enter, so it is not so strict. You can look around the campus, but the library can't get in without a student ID card, not to mention it hasn't been opened recently. Hehe ~ ~ I suggest you go to the main square, the path behind the computer center, the gymnasium and the research teaching building. These places are not bad, hehe ~
As for maritime affairs, it should also be open. It takes 10 minutes to walk from Dagong to Dongshan (marine engineering and navigation). Dongshan Mountain is general, and Xishan Mountain is worth visiting ~ ~
Have fun ~ ~
