To determine whether a book was genuine, one could check the information such as the publishing house and the date of publication. You can search for the name of the publishing house online to see if there are online reading or download resources for the book, or if there are reports of copyright disputes or pirated issues. If the book was published by Huacheng Press and the publication date was within the legal range, then the book was likely to be genuine. In addition, you can check the official website of the bookstore to confirm the copyright status and purchase method of the book. It is recommended that when purchasing genuine books, you choose reputable editors and online bookstores to ensure the quality and copyright of the books.
