Gu Kuangsheng, whose life remains obscure, has an unknown real name, native place, and dates of birth and death. Only one work by this author survives, a book titled Zui Xing Shi (roughly, The Sobering Stone), classified in the library under social sciences. From the title and category alone, its specific content and structure cannot be confirmed, though the words "drunk" and "awake" carry a tone of admonition and moral awakening, suggesting a connection to writing on worldly conduct and edification. Because public information is limited, it is impossible to trace the author's intellectual lineage, circle of associates, or the circumstances of composition, nor to judge how widely the book circulated in its time. For readers today, Gu Kuangsheng is mentioned chiefly on account of Zui Xing Shi, and both the author's identity and the work's attribution still await further verification.
