Common counterfeiting methods include the following: First, dyeing. Ancient books from a relatively recent period are dyed to pass them off as older editions, and modern photocopies are even dyed to pass them off as older editions. The more common method is to use tea water for spray dyeing, with different shades. The book is full of botched counterfeiters to save trouble. The slightly finer ones gradually become lighter from the edge of the book to the inside, resulting in a naturally formed old image. The second is insect infestation. Ancient and old books have been circulated for many years and are inevitably infested by insects. Counterfeiters take advantage of this feature to artificially create the illusion of being infested with insects. What's more, some even deliberately damaged the corner of the book and the edge of the book. In addition, professional forgers will place the damage on the key points of the ancient book’s publication year and publisher’s identification, thereby causing erroneous judgments. The third is to mix the fragments into a book to create the illusion of a complete book. The counterfeiters will mix two or more fragments into a book. The sophisticated ones will choose books of the same type or the same edition in different volumes to assemble them, while the crude ones will only use Combine any book of the same format. The fourth is to delete and modify the catalog and volume number of ancient books. The table of contents at the front of the book was deliberately deleted to create a correspondence between the number of volumes and the table of contents and to conceal the incomplete truth. Or change the content of the same volume into two or three volumes.
