An imaginary historical novel could quote characters or poems that really existed, but one had to pay attention to the accuracy of the quote and the background explanation. Quoting real characters or poems from the era required the accuracy of their identity, status, historical background, and relationships. If the background of the novel is an era that exists in real history, then it is necessary to give appropriate background explanations to the quoted characters and poems so that the readers can understand their environment and the background of the era in order to better understand the plot and the relationship between the characters. In addition, fictional historical novels often required the use of fictional characters and events. These characters and events also needed corresponding backgrounds and settings to avoid conflict or contradiction with real history. When using real-life characters or poems, you need to pay attention to maintaining accuracy and background explanations so that readers can better understand the plot and character relationships of the novel.
