I bought books on Dangdang for about 1000 yuan, and there was no piracy. As for the appearance of the book, if you choose surface mail, there will be some wear and tear on the way, but it is not serious. It is normal and does not affect reading. And it is definitely a new book. Dangdang is one of the largest book buying websites in China, which is credible. It is because the price is cheap that it can be made so big. However, it is a pity that Alipay payment is not supported.
