Because Weihai has an aid program for Shanda Library, provided that Shanda Library is open to the public free of charge and should be barrier-free. But you need a library card. If you can't get in, ask your classmate to tell him that you forgot to bring your card when you were a student and ask him to help you borrow the card inside.
He sends it out, you can go in together. Ordinary students will help you, so you can't verify it if you don't worry.
You can enter the study room at will, nobody cares.
