Stendhal's novel, Red and Black, tells a story about social class division and moral values in France in the first half of the 19th century. The protagonist of the story was Francois Stendhal's fictional character, Rastine. He was born into a noble family, but as time passed, he gradually realized that his social status and lifestyle were wrong. He tried to get rid of his noble identity, but in the process, he suffered all kinds of difficulties and setbacks. In the novel, Stendhal described the gap between the social classes in France and the moral and ethical problems faced by people of different classes from the perspective of Rastine. Rastinie's neighbor, the doctor, Charles-Francois Bertrand, and the noble lady Bernadette made all kinds of incomprehensible behaviors under the influence of different moral values and social status. Through the experience of Rastine, the novel explored the problems of morality, social status and interpersonal relationships, and also revealed the gap and injustice between the social classes in France.
