A literary genre refers to a literary style, literary tradition, or a collection of literary styles, usually with unique aesthetic characteristics and creative methods. There were many literary schools, including classical literature, modern literature, romanticism, realism, realism, post-realism, and so on. In the field of novels, literary schools were often used to refer to different writing styles and narrative methods. For example, many classic works in classical literature, such as Dream of the Red Chamber and Journey to the West, used traditional narrative methods and character creation methods. Modern novels, on the other hand, adopted more modernist writing styles, such as the Sun Also Rises by Ernest Hemmingway and The Sound and the Fury by Faulkner. Different schools of novels also have different literary characteristics and topics. For example, realist literature usually focuses on social reality and the description of characters, while romantic literature pays more attention to the expression of emotions and human nature. Therefore, understanding different literary schools would help one better understand and appreciate different literary works.
