Tragedy and comedy were two common forms of emotion in literature, but they were fundamentally different. Tragedies usually describe the sadness and misfortune in human life and resonate with the readers by telling tragic stories. The main purpose of tragedies is to make readers feel the fragility of life and the dark side of human nature, so as to reflect on human behavior and decisions. Comedy, on the other hand, produced joy and joy by displaying human wisdom, kindness, good wishes, and hopes. The main purpose of a comedy was to let the readers feel the beauty and hope in life, so as to have a positive view of life and the world. Although tragedies and comedies can both arouse the readers 'emotional resonance, their purposes and methods of expression are obviously different. Tragedies were more about delivering sadness and reflection through tragic stories, while comedies were more about delivering joy and joy through displaying beauty and hope.
