Mo Han Zhuren is a pseudonymous author whose real name and life remain unknown. Only one work by this author survives, Twelve Laughs (Shi'er Xiao), commonly classified as classical literature. Due to limited public information, nothing certain can be established about the author's native place, dates of birth and death, or the origin of the sobriquet; only the pen name and the work itself offer a glimpse of the author. Judging from its title, Twelve Laughs is likely a collection of short stories built around the theme of laughter, close in style to the humorous fiction of the Ming and Qing periods, using ridiculous people and absurd situations to convey moral instruction and social satire. This approach forms a distinct strand in classical vernacular fiction, treating human nature and social manners in a light tone so that readers may reflect on the warmth and coldness of the world amid laughter. The name Mo Han Zhuren resembles the "Mo Han Zhai" studio name of the late-Ming writer Feng Menglong and may reflect his influence, though this cannot be confirmed. Despite consisting of a single work, it still reveals the author's thematic interests and linguistic taste.
