1. Low content quality: pirated books often have quality problems in printing, binding and translation, which leads to poor reading experience. Children may not get high-quality knowledge and information from it.

2. Legal risk: It is illegal to buy and use pirated books, so children may break the law and have a negative impact on their growth.

3. Affect values: pirated books infringe the intellectual property rights of authors and publishers, and children may have a wrong understanding of this behavior during reading, thinking that infringing on the rights and interests of others is tolerable.

4. Lack of choice of genuine books: Pirated books occupy the market, limiting the choice of genuine books, and children may not have access to more high-quality book resources.

5. Affect reading interest: pirated books often attract consumers at low prices, but the quality and content cannot be guaranteed. Children may have negative views on reading, which will affect the cultivation of their interest in reading.

6. Impact on libraries and publishing houses: Pirated books weaken the economic strength of libraries and publishing houses, which may lead these institutions to reduce the purchase of new books, thus affecting children's reading resources.

In order to protect children's reading experience and cultivate good reading habits, parents and teachers should encourage children to buy and use genuine books, and at the same time, they can popularize copyright awareness to children and let them know the importance of respecting intellectual property rights.
