What are the four parts of a novel's plot?

The four parts of a novel's plot generally depended on the genre and theme of the novel. But generally speaking, the plot of a novel could be divided into three main parts: The first part: The beginning is usually the starting point of the story and the foundation of the story development. This part usually described the protagonist's background, personality, experiences, and problems. Part Two: Development This part is the main part of the story and the main stage of the story development. In this part, the protagonist gradually grew and changed through a series of events and adventures, and solved the problems he had encountered before. The third part: The climax is usually the climax of the story and the end of the story. In this part, the protagonist would face greater challenges and tests, perhaps experiencing life and death tests or reaching a peak of his own and making a summary and reflection on his previous life. The plot of a novel can also include some additional parts such as the ending and the side story. These parts are usually used to supplement and deepen the plot or to provide more imagination and thinking opportunities for the reader.
