In fact, except for the textbooks that freshmen are forced to buy, we usually copy them. Generally speaking, about ten yuan! Or when seniors leave school every year, they will sell old books at a price of two or three yuan each. And you can borrow books from the library! The university library has a huge collection of books, a knowledge system, and even magazines and newspapers. Don't worry about having no books to read! Of course, if you buy books too expensive, buy pirated books. The quality is almost the same, three or four times cheaper.
