Is Confucius' old book network a lie?

The price of garbage platforms is exorbitant, and many books are neither out of print nor only sold by them, making them look like priceless treasures. The same book, the regular website Dangdang Taobao has a genuine book for sale, and the price is also lower than the book pricing. However, the seller of Kongwang is disgusting, and the price of the same book is several times higher than the price. Especially books such as calligraphy art. I'm crazy about money, and one can be a group of bad garbage merchants! Pure disgust!
