What is the quality of Confucius' old books?

As the name implies, Confucius second-hand book network certainly sells second-hand books. But some so-called second-hand books only refer to the backlog stored in the library, so some books are better, just like new books. Nine finished products should be good.

If you are still not at ease, you can go to Dangdang Zhuoyue to buy it. If you are not satisfied with the book, you can go there to return it. After all, Confucius secondhand book network is mainly a place to sell secondhand books. Some books are out of print, so I will consider buying them there if I can't buy them. And the discount is not much different. Also, online shopping is risky after all, so pay more attention.
