There are two ways to buy genuine books online.

The first way is to go to regular online stores such as Amazon, JD.com, Dangdang, etc., which sell genuine books uniformly;

The second way is to go to the official website of the publisher to buy genuine books from the publisher, such as Panda, CITIC, etc. There is only one way to distinguish fake books from real books, which is to check whether the paper and content of the book have been precisely typeset or whether there are typos, and compare it with the genuine book. There is a difference in quality between pirated and genuine books.
