Abstract: The episode of JIA Baoyu Being Beaten acts as a pivotal plot that links the novel’s preceding plots to its subsequent ones in A Dream of Red Mansions. Furthermore, this episode serves as a crucial window, allowing readers to discern significant insights from minor details within the story. From the holistic perspective of familial power struggle, this conflict unveils the existential crisis of succession lurking beneath the surface of the well-disciplined parenting of the declining aristocracy. Moreover, it touches upon the deeply entrenched and long-standing triple contradictory relationships between father and son, the hierarchy between sons of the principal wife and concubine-born sons, and mother and son. All the triple contradictory relationships are concealed beneath the facade of the Rong Mansion’s thriving population. The plot can be regarded as a milestone in Baoyu’s growth. In this context, tracing his maturation reveals an evolving family transformation. This transformation unfolds from an early pattern marked by a strict father and doting mother to a later reversal, where the father becomes indulgent and the mother increasingly stern.
