It seems that each library has different procedures for obtaining library cards and borrowing books.

I have been to two different cities.

One is to change the library card into the library board at the door when you go in, and then go in and pick it out.

When you come out, change the library board into a library card, give it to the administrator together with the book, then register it on the computer and you can go.

In another library, you don't need anything to go in, because simply reading books is free of charge. Pick out the books when you come out, then give the library card and books to the librarian, register and go.

In fact, people in libraries generally have a good attitude. If you don't understand it for the first time, you can read the introduction or ask others, and the familiar ones will be easy to master ~ ~
