A 1: As far as the National People's Congress is concerned, some majors have their own college libraries, and only students of this college can enter, which is inconvenient! Moreover, the variety, quantity and quality of books are definitely not as good as the national map.

The service in Guo Tu is the best in all libraries, and the environment is first-class. The university library must not have free water than Guo Tu (you can bring a cup).

A3: If it's self-study, of course, the school library will do. After all, it's near, but it's still a national map to find information or something.

A4: The national map has wireless network, and the National People's Congress teaching area has wireless network. I'm not sure if the library has it. Peking University doesn't know ~

The national map can be accessed with an ID card, and the university library must have a school card. Therefore, the national map is recommended.
