Side descriptions were a literary technique that portrayed characters by describing things, environments, and plots outside of the characters, allowing the readers to have a deeper understanding of the character's personality, psychology, and behavior. For example, in the novel " One Hundred Years of Solitude," the author, Marquez, described the history of the Marquez family and the relationships between the characters to show the various defects and contradictions of the family, allowing the readers to have a deeper understanding of the fate of the family. This was an example of a side profile. In writing, side descriptions are a common literary technique that can make the work more vivid, profound, and rich. At the same time, it can also help readers better understand the story and characters. However, it should be noted that side descriptions could not replace positive descriptions. Positive descriptions were the main means of depicting characters.
