Kongwang is the largest book trading website at present. When it was first established, it was mainly second-hand books. With the continuous development, more and more people know about it. Many publishing houses have online stores in Kongwang, and the books they sell are not limited to old books. Many new books or books published by publishing houses in previous years are also traded online. Of course, the sources are different. I am one of them, and the above is just my hole. ! !
