What is the difference between children's literature and adult literature?

There are too many differences between children's literature and adult literature, which can be seen from the genre theme of children's literature (such as children's poems, fantasy stories, picture books, myths and fairy tales), the knowledge base of children's literature (characters, stories, theme structure, style and focus), the ideology, history and culture, gender, politics and pluralism of children's literature, the cultural world of children's literature, the world of children's understanding, children's toys and so on. In every category, there are differences between children's literature and adult literature, and every text of children's literature and adult literature is different. Every large area can be broken down into small points, and each small point can be written as a monograph or dozens of monographs. Therefore, the question or study of literary problems should focus on in-depth study from the nuances.
