Daughter-in-law to Jia Zhen. Of all the characters in the novel, the circumstances of her life and early death are amongst the most mysterious. Apparently a very beautiful and flirtatious woman, she carried on an affair with her father-in-law (as claimed by Jiao Da in chapter 7) and dies before the second quarter of the novel. Her bedroom is bedecked with priceless artifacts belonging to extremely sensual women, both historical and mythological. In her bed, Baoyu first travels to the Land of Illusion where he has a sexual encounter with Two-In-One, who represents Xue Baochai and Lin Daiyu. Two-in-One's name is also Keqing, making Qin Keqing also a significant character in Baoyu's sexual experience. The original twelve songs hint that Qin Keqing hanged herself even thought the cause of her death isn't specified in the chapter 13, chapter in which she dies.
