When buying books in Pinduoduo, the words "brand" behind the store name or in front of the commodity name are basically genuine books, and the price is relatively expensive. Besides, other stores also have genuine products, so we have to identify them carefully. The same is true of Taobao stores. Just because a general business store or Tmall is less likely to buy pirated books doesn't mean there isn't one. I bought it at Tmall, and the other party will only return it if they take a photo of the same size as the genuine book.
If you don't mind buying pirated books to save money, or want to buy out-of-print books, you can still buy books in Pinduoduo or Taobao, but it will only affect the reading experience, and you won't be able to sell them in the future, just like none of the books handled by book lovers for catching more fish have passed the acceptance test.
2. Confucius Old Books Network
Now Confucius' old book network is not as good as before, and he buys pirated books, especially books marked "brand-new". When you see the out-of-print books that can't be bought by major websites, the new books that are normally priced in Confucius are basically pirated. Look at the store's recent transactions, evaluations and grades before buying. Generally, old shops don't sell such books.
So when you buy books about Confucius, as long as you see actual pictures and books with reasonable prices (expensive ones), they are generally genuine books or even new books. Other old books are rarely pirated unless the shopkeeper doesn't know that there are pirated old books on his bookshelf, but this is rare. Relatively speaking, Confucius second-hand book network is still an important channel to buy genuine books.
3.JD.COM, Dangdang and Zhongtu.com.
Let me start with China Book Network, an old website founded in 1998. Not expensive, and they are all genuine books. It's a pity that some books I bought are second-hand, and the title pages have been torn off. Although I can return it, I didn't return it because of the trouble. In fact, when picking goods, as long as you hold them in your hand, you can see that they are old books, indicating that they still deliver goods with the psychology that customers are too troublesome to return them.
JD.COM and Dangdang can buy their own books with confidence, but third-party sellers outside the flagship store of the publishing house cannot guarantee to buy genuine books. If you see that your store or flagship store is out of stock, but other stores have it, you have to ask if it is genuine. If the other party replies "just like a picture, you can return it if you are not satisfied", then you can judge it as piracy and never buy it.
