You mean teaching books, right? The first thing is to go to Xinhua Bookstore. But the textbooks of our school are all imported from Xinhua Bookstore. We all need several sets of books in the bookstore, and there are few books left. I bought it before, but I haven't been to Xinhua Bookstore, but there are still one or two, depending on your luck, but there is still one.

Hero Mountain cultural market,

You should go, right? Where do you sell books and things? Anyway, you have to sell more cultural things. There are many books and everything. You should go to them. If you really don't have one, you can make a copy, or get on well with your teacher and use his. I have given you all the ideas I can think of. Pick me, hehe.
