Editions disagree on this lot. Two name Su Xiaomei testing her husband, one names Su Qin stabbing his thigh to stay awake over his books, and a second story in one edition tells of a lowly army cook who talked the Yan generals into freeing the captive King of Zhao. The Su Xiaomei tale suits the poem best. In a Ming story collected by Feng Menglong, Su Xiaomei, the brilliant younger sister of the Song poet Su Dongpo, set her new husband Qin Shaoyou three literary puzzles on their wedding night before he could enter the bridal chamber. He was stuck on the last couplet until Su Dongpo slipped him a hint. The sister is a figure of legend, not history. Poems at dusk, singing under the moon and a couple joined at the end: a happy middle lot that still leans on a helper.
