Online literature and traditional literature are two different forms of literature. Although they have similarities in some aspects, they also have many differences. Therefore, the integration and symbiosis of online literature and traditional literature was not a simple problem. Online literature usually used electronic media as the main platform, such as novels, comics, games, etc., which had an interaction and multi-media nature. Compared with traditional literature, online literature paid more attention to expressing personal feelings and thoughts, emphasizing storytelling and innovation. At the same time, online literature also had a wide audience and social media influence, which made online literature more disseminated and trending. Traditional literature paid more attention to the formality and professionalism of paper media such as novels, essays, and poems. The writing style and theme of traditional literature were relatively fixed. It often took a long time to write and repeatedly revise before it could be polished into excellent works. Traditional literature also had a wider readership and a more professional publication market, which made traditional literature more valuable and meaningful. Although there were differences between online literature and traditional literature, they also had many similarities. Therefore, the integration and symbiosis of online literature and traditional literature needs to maintain their own unique characteristics while finding common ground, strengthening communication and interaction, creating more innovative and practical literary works to meet the needs of readers and promote the development and prosperity of literature.
