There were usually several differences between the author of a novel and the original: 1. copyright and ownership: the author of the novel usually owns the copyright and ownership of the novel, which means that they can freely modify, create, publish, and share the novel. The owner of the original work was usually the copyright owner of the novel, such as the publishing house, distribution company, etc. They had all the rights of the novel, including modification, adaptation, re-creation, etc. 2. Writing style and style characteristics: The author of the novel may create the novel according to his own writing style and characteristics. For example, the author may add his own personal elements, emotions, and opinions. The original work would usually maintain the original style and characteristics of the novel, perhaps more faithful to the original form of the novel. 3. Revise and edit: The author of the novel may modify and edit the novel to suit his own writing style and target audience. The owner of the original work would usually carry out more in-depth editing and modification to ensure the quality of the novel and meet the publishing standards. 4. Promotion: The author of the novel may promote the novel to attract more readers. The owners of the original works would usually promote it more widely, including through social media and publishing channels. The difference between the author and the original novel was usually in copyright and ownership, writing style and style characteristics, modification and editing, and publicity.
