All the genuine books I sell in the book market are affixed with "Zheng Authorized" anti-counterfeiting marks. This is the new "Zheng Authorized" anti-counterfeiting logo launched by "The Story of Pipiru". Illuminated with a money detector, there is a watermark in the anti-counterfeiting logo. Without this anti-counterfeiting mark or with an anti-counterfeiting mark and no watermark, it is a pirated book. Now the Z Planet prop card is genuine, if not, look at the watermark.
