There are three points: first, create typical characters in typical environments. The formation of the complex and contradictory character of the hero is caused by the specific social environment in which he lives, and also changes because of the change of the environment. The author successfully described the specific environment in which Julien lived: mercenary Villiers, gloomy Besancon College and shady aristocratic society in Paris. These three environments affect Lian's character and development from different angles.

Second, the psychological representation of success. The author firmly grasps the hidden inner activities in a specific environment and shows his complex and contradictory personality characteristics. For example, writing about his changing psychological state in the process of falling in love with the mayor's wife and marquis fully shows the sharp struggle between cowardice and courage, hesitation and firmness, inferiority and self-esteem, which makes this image vivid, natural and true to readers.

Third, the plot is compact and the structure is rigorous. Taking Julian's personal struggle history as the "warp" and his love life with Mrs. Drina and Miss Margaret as the "weft", the warp and weft are intertwined and consistent. The transition of the three typical environments is natural and smooth, and the characters are all related to the protagonist. The characters, plot and environment all appear to be clearly verified and orderly, forming an organic artistic whole.
