The reason why Chinese sci-fi novels left people with a particularly vulgar and crude feeling was that they were often influenced by Chinese culture and social reality. They often focused on expressing personal feelings and desires and ignored the deeper and more complicated human subjects. Chinese sci-fi novels were often created by experienced people who might have a deep cultural background and life experience, but they often lacked the language and narrative skills of western sci-fi novels. Therefore, they may appear too simple and lack depth and beauty. Chinese sci-fi novels tended to focus on the grand history and worldview while ignoring the details and human nature. This made it difficult for them to explore the problems and challenges facing mankind in detail like western science fiction. Finally, due to political and cultural constraints, it was often difficult for Chinese science fiction to obtain the freedom of creation like Western science fiction. This also made it difficult for them to get rid of the shackles of traditional culture and obtain a broader development space in the field of science fiction.
