Ladies and gentlemen, where is the place to recycle old books in Tongzhou, Beijing?

The southwest of Ximen Road intersection in Tongzhou District, Beijing (diagonally opposite to Century Lianhua Shopping Mall in Xinhua Street) is Tongzhou Ximen Market. There is a second-hand market to the south of the market. There are three shops specializing in buying and selling second-hand books in the second-hand market, and they will buy second-hand books according to their quality and variety. There is really no contact information. You can take a bus from the Canal Middle School.
