First, look at the handwriting.

Genuine books are printed with clear handwriting, while pirated books may have turbid handwriting, even mottling and ink leakage because of their low production cost. In addition, typos in pirated books are more likely to appear.

Second, look at the publishing house

Because most pirated books are made by small factories and workshops, publishing houses are usually removed, while genuine books have the name, telephone number and address of the publishing house.

Third, look at the bar code

Authentic drawings will have bar codes, which can be found online. The number on the bar code is the ISBN number of the book, also known as the book number. The book number of each book is different, even the book number of the same supplementary book in different disciplines and grades will not be the same. In pirated books, a series of books often use the book numbers of several publishers. In addition, pirated books have no QR code and anti-counterfeiting code, so they can't be searched in official website.

Fourth, look at the packaging.

Genuine books are copyrighted, the packaging looks transparent, and the cover generally has obvious signs of genuine books. The packaging of pirated books is rougher than pirated books.

Fifth, look at the price.

Genuine Books Because of the copyright fee of the copyright owner and the cost of books, paper and materials, some books will not be too close to the people. Pirated books do not need copyright fees, all pirated books are extremely low in cost, and the price of pirated books that are often circulated in the market is also lower than that of genuine books.
