Jia Yucun helps Daiyu's uncle, Jia Zheng, and is reinstated. Daiyu becomes close to her cousin, Jia Baoyu, but Wang Xifeng, a daughter-in-law, schemes to marry Baoyu to Xue Baochai, a relative of the family's matriarch. When Baoyu falls ill after losing a jade, the family forces him to marry Xue Baochai, pretending that she is actually Daiyu. Daiyu is heartbroken and dies shortly after. The family eventually declines, and Baoyu becomes a monk.
