Doujinshi referred to novels that were created based on film and television IPs. They usually re-created the characters, scenes, and plots of the original film and television works to create their own stories. In the field of online literature, signing a contract referred to signing a contract, publishing a book, and other rights. If you want to sign a contract with a fan writer, you need to pay attention to the following points: 1. The work should meet the market demand: the writing direction should meet the reader's preferences and have a certain audience. 2. Beautiful writing and attractive storyline: You must have enough literary attainments and creative ability to attract the attention of readers. 3. Have sufficient creative ability: In the second creation, you must grasp the IP value of the original film and television works to create works with uniqueness and value. 4. Strong willingness to cooperate with the platform: to cooperate with the platform and actively communicate with the platform to display works to increase exposure. The creation of film and television doujinshi novels was challenging, but if one had enough literary attainments and creative ability to meet the market demand and platform requirements, then there was great potential for development. I suggest you pay more attention to market trends and actively communicate with the platform to improve your creative level so that you can sign a contract to get royalties and publishing rights.
