The video of book promotion is not easy to infringe.

Because your book is just a promotion, then you didn't use some of the contents of this material for oral play, or directly play some of the contents or plots of this book, so it won't cause infringement. This kind of behavior only exists for promotion, and there will be no infringement.

According to the relevant laws and regulations of copyright protection in China, recording reading into a video for the purpose of learning, communication and sharing, whether it is privately watched or uploaded to the network, does not constitute infringement.

However, for the purpose of making profits, recording reading into a video for distribution without the permission of the copyright owner constitutes infringement. However, books whose copyright protection period has expired under the author's name, whether or not they record videos for profit, are not regarded as infringement.
