1, look at LOGO. Although the imitation is very similar, but careful identification can still see some subtle differences. My first real book was hand-embroidered, with clear lines. The fake part is that the names will be very similar, but there are subtle differences, such as First Book or My Book. Logo will be deformed to a certain extent, and even some imperceptible trademarks will be added to mislead consumers.

2. Just scan the bar code of my first book with my mobile phone.

3. Look at the material. All the materials used in my first book have passed six national safety certifications, which are tasteless and nontoxic. Many pirated products are made in small workshops, and the materials used are also very casual, with a dusty smell and rough sewing, and some are made of inferior cardboard as interlayers.
