尹夫人 / Lady Yin (Cao Cao)
尹夫人 / Lady Yin enters the wiki through Hanji 1013 as the widowed daughter-in-law of 何进 and the mother of 何晏. The source says 曹操 takes her into his household after her husband dies.
Lady Yin’s main role in this episode is connective. Through her, the source moves from Cao Cao’s household conduct to He Yan’s later cultural afterlife, including beauty, incense, drug use, and qingtan as parts of 魏晋风度文化后效.
