There were a few points to note when writing doujinshi: 1. Respect the original work: Doujinshi is created on the basis of respecting the original work. It cannot distort, tamper with or defame the original work, and it cannot violate the copyright of the original author. 2. Prominent elements of the original work: Doujinshi should emphasize the elements and characteristics of the original work such as characters, plot, background, etc., so that readers can understand and accept them more easily. 3. A reasonable integration of different cultures: Doujinshi is a cross-cultural creation that requires a reasonable integration of different cultural elements and characteristics to make the work more diverse and readable. Pay attention to the writing style and language: The writing style and language of the doujinshi should be similar to the original work but not too simple or plain. It needs to have a certain degree of expressiveness and appeal. 5. Prominent character's personality: Doujinshi should highlight the character's personality and characteristics so that readers can easily understand and like the character, and be able to resonate and move from it. 6. Maintain continuity and integrity: Doujinshi must maintain continuity and integrity without any logical errors or contradictions. At the same time, it must be consistent with the original plot and character settings. Writing a good doujinshi required a deep understanding of the original work and a reasonable creation and expression based on one's own creative inspiration and cultural background.
