Abstract: Laughter and Tears revolves around “jokes” and builds a complex world of jokes based on the essence of jokes in the real world. The artistic charm of Laughter and Tears is not only reflected in the profound meaning behind jokes, endowing “jokes” with richer connotations, realizing the artistic expression of “jokes” in the novel, but also in the structure of the novel with “jokes” as the core, connecting the human world, dreams, and ghost realm, making it always revolve around the life trajectory of the characters and expressing the unspeakable content of life clearly. All of this can be attributed to LIU Zhenyun's aesthetic pursuit of smile and tears, his conscious adherence to the folk standpoint, and his persistent pursuit of philosophy.
