The original work referred to the original direction of a literary work, the content and emotional clues that the author originally wanted to express. The original work was usually regarded as the core and soul of the work, which was the key to understanding the work. Doujinshi referred to the second creation of the original work. It was usually an adaptation, continuation, translation, etc. of the original work to make it have a different cultural background and audience. Doujinshi works usually deviate from the original work, sometimes even completely, but their purpose is to express the specific feelings, values, or cultural background of the author or the audience. The relationship between the original novel and the people of the same genre was complicated. On the one hand, the original work was regarded as the core and soul of the literary work, which was the key to understanding the work. On the other hand, the creation of the same culture aims to express the emotions, values, or cultural background conveyed by the original work and provide readers with different reading experiences. In addition, doujinshi novels could also cause distortions and misunderstandings in the original work, damaging the reputation and value of the original work. Therefore, we should maintain a prudent and critical attitude towards the original works of literature and readers of the same language in order to better understand and appreciate literary works.
