Abstract: LI Shangyin's poems often use allusions of the Gao-Tang (高唐) Goddess, and the poem "Stirred by Something" conveys a certain sense of defense. But after the completion of the Gao-Tang (高唐), the clouds and rain of Chu became suspicious, and both the rain and clouds of Chu had sustenance, which became a certain suggestion and sparked various speculations from later generations. The traditional metaphor of Vanilla Beauty provides a basis for this interpretation path, and the proposition of "why the author is right, why the reader is not" gives the interpreter power. These two reasons together constitute the path and history of LI Shangyin's "Untitled" poetry interpretation, which not only strongly guides the interpretation of LI Shangyin's poetry, but also affects the writing of "Untitled" poems after him.
