Friends who love literature, what is popular literature and what is pure literature?

Popular literature usually refers to literary works that are targeted at the general public and are featured by easy-to-understand language and storylines. The theme and style are often more extensive, not pursuing depth and complexity, but aiming to satisfy the entertainment and entertainment needs of readers. Pure literature, on the other hand, focused more on depth and complexity, often based on the author's personal views and experiences, pursuing deeper thinking and exploration of human nature, society, and history. Pure literature works often required a higher level of literary attainment and reading level, and the language and artistic forms were more cumbersome and complicated. Of course, this was just a general definition. In fact, there were many different literary schools and types, such as classical literature, modern literature, science fiction literature, horror literature, etc. They all had their own characteristics and targeted readers.
