Positive descriptions, side descriptions, and the combination of positive and side descriptions were a rhetorical technique used in novel writing to describe characters, scenes, plots, and so on. The specific explanation was as follows: 1. Positive description: Directly show the positive characteristics and images of the characters or things, so that the readers can directly feel their emotions and style. For example," she has a pair of bright eyes "," he is tall and strong ". 2. Side description: By describing other aspects of a person or thing, indirectly showing its image and characteristics. For example," He's gentle and doesn't like to talk "," Her family is very rich and has many luxury goods." 3. Combining the front and side: Combining the front and side descriptions to show both the positive characteristics of the person or thing and the side characteristics. For example," He's tall and strong but gentle and is a good husband and father "," Her family is rich and has many luxuries but I know she's actually a very frugal person." Positive descriptions, side descriptions, and the combination of positive and side descriptions were all commonly used rhetorical devices in novel writing. They could allow readers to have a deeper understanding of the characters, plots, and scenes, enhancing the novel's expressiveness and artistic appeal.
