This renowned work was composed by Liu Guo during his revisit to Anyuan Tower (also known as South Tower) in Wuchang. Situated on Huanghe Mountain in modern Hubei, Anyuan Tower served as a strategic military base during the Southern Song's resistance against the Jin dynasty. Twenty years after his youthful revelries here, Liu returns to find the landscape unchanged but human connections severed—friends scattered, the nation in turmoil. Through autumn scenery and introspective lament, the poem distills life's transience, national grief, vanished youth, and lost companionship. Its iconic line—"I'd buy osmanthus and wine for old-time cheer, / yet never taste that carefree spirit of my youth"—has resonated for centuries as the ultimate expression of temporal irrevocability.
