I heard that if you read a book online, is there a copyright problem?
The copyright issues involved in reading novels or other literary works on the Internet were decided by the copyright owner. If the copyright of the work has already belonged to an organization or individual, then any form of communication on the Internet may violate copyright, including online reading. Therefore, if you want to read novels or other literary works on the Internet, it's best to confirm the copyright status of the work and abide by the relevant regulations of the copyright owner. If the copyright of the work has not yet belonged to any organization or individual, it is legal to read it on the Internet. However, if you want to adapt the works you read into other forms of work, such as writing, making a movie or TV series, you need to obtain the permission of the copyright owner first. Without the permission of the copyright owner, any form of adaptation was illegal.
