The Dream of the Red Chamber

Baoyu is married to Baochai because the family elders, Grandmother Jia, Lady Wang, and Xifeng, scheme to secure the Jia bloodline. They believe Daiyu is too frail to survive childbirth, while Baochai is seen as healthier and more suitable to continue the family lineage. They also hope the marriage will cure Baoyu's manic episodes, using deception to make him believe he is marrying Daiyu.

Early on, Daiyu's frailty is established when she arrives at the Jia household as a sickly adolescent, setting the justification for the family's decision.

Jia Zheng beats Baoyu after he helps the prince's favorite actor escape, an act that brings scrutiny and pressure onto Jia Zheng to locate the runaway actor. This defiance of his father's strict expectations, combined with Baoyu's refusal to focus on studying for government exams, triggers Jia Zheng's harsh punishment.

Baoyu's strained relationship with his father is evident from the start, as Jia Zheng constantly pushes him to pass exams and abandon his literary pursuits.

Daiyu's health declines due to a combination of her frail constitution from childhood and the emotional turmoil caused by her relationship with Baochai. Her jealousy intensifies when she sees Baochai gaining Baoyu's attention, and learning about the secret wedding plan accelerates her decline into illness and death.

Daiyu arrives at the Jia household as a frail adolescent after her mother's death, establishing her vulnerability from the beginning.

The family conceals the wedding plans because they need Baoyu to cooperate with the marriage to Baochai. They believe he would refuse if he knew the truth, so they trick him into thinking the bride is Daiyu. This deception is meant to protect the family's future and supposedly cure Baoyu's madness, even though it ultimately destroys both lovers.

The conspiracy begins after Zijuan's prank triggers Baoyu's breakdown, giving Grandmother Jia and Lady Wang justification to take control of his future.

Baoyu's manic breakdown is triggered when Zijuan plays a prank on him, pretending that Daiyu is moving out of the Jia mansion. The false news sends Baoyu into a frantic state, causing the household to intervene and Grandmother Jia to order that Daiyu remain in the mansion.

Earlier, Daiyu had expressed intentions to return to her own family, providing the setup for Zijuan's cruel trick.

Baoyu becomes a Buddhist monk after two devastating losses: Daiyu dies just as he discovers Baochai is his bride, and the emperor's decree strips the Jia family of their wealth and position. With his beloved dead and his world collapsed, Baoyu rejects worldly attachments entirely and seeks spiritual refuge.

Baoyu has always shown indifference to material success and societal expectations, preferring literature and poetry over official career paths.

The emperor removes Jia Zheng from his government post and confiscates the Jia family's assets because the family has lost the emperor's trust. This likely stems from the incident where Baoyu helped the prince's favorite actor escape, bringing shame and political consequences to the family.

The earlier escape of the prince's actor creates political trouble for Jia Zheng, establishing the family's vulnerability to imperial displeasure.

Daiyu withdraws emotionally because she sees Baochai leaving Baoyu's residence at night, believing Baoyu's feelings have shifted. Her fragile emotional state and jealousy cause her to push Baoyu away, even though he tries to reassure her. This emotional distance deepens her tragedy, rejected by the one she loves while the family secretly arranges his marriage to another.

Baochai's arrival and her captivating presence over Baoyu marks the beginning of Daiyu's jealousy and withdrawal.

The family elders favor Baochai because they view her as more suitable to continue the Jia bloodline, Daiyu is seen as too frail and sickly to survive childbirth, while Baochai is healthy and intelligent. They also believe marrying Baochai to Baoyu will stabilize his mental state and secure the family's future.

From her arrival, Baochai is presented as calm, intelligent, and capable, everything the family believes Baoyu needs for a proper marriage.

Daiyu's funeral is barely attended because the family keeps her death secret to avoid scandal during the wedding celebrations. Only Zijuan, her loyal maid, and Baoyu are present to mourn her. The contrast between the grand wedding and this somber funeral underscores the tragedy of Daiyu's forgotten life.

The wedding is rushed forward while Daiyu lies dying, showing the family's priority on the marriage rather than her wellbeing.
