Are the books in Yunnan Province bigger than those in the city library? What documents do I need to apply for a library card? How much does it cost?

Of course, the Yunnan Provincial Library is bigger than the municipal library, at least it has more books than the municipal library.

If you want to apply for a library card, you need an ID card and take photos in person.

As for money, it depends on what you want to do.

I got one when I was in college in 2005.

If you only study in it for one year, if you don't borrow it, you have to pay it to 50 yuan for one year.

If you want to lend this book, you need a deposit 100, and it will be returned to you after one year, valid for one year.

As for other kinds, you'd better go to the library. I forgot too.

Get a student ID card. Just try it. It should work.
