From different starting points, choose different angles, adopt different techniques, and describe the same type of events in a positive and obvious way many times to achieve completely different artistic effects. Jin Renrui (Jin Shengtan) summarized this view in "Reading the Calligraphy of the Fifth Talent": "There are serious crimes: for example, after Wu Song killed the tiger, he wrote Li Kui to kill the tiger, and then wrote two interpretations to fight for the tiger." In "Water Margin" After writing about the robbery of the law field in Jiangzhou City, he also wrote about the robbery of the law field in Daming Mansion. The two tribulations are roughly the same. Due to the author's ingenuity, he seeks avoidance while committing crimes, develops his individuality while seeking differences among similarities, and truly achieves the description of the two tribulations, "without any difference." The words and pictures are the same."
