Mi Zhu Binding Himself to Plead Guilty Case

In 219 AD, during the Three Kingdoms period, Mi Fang, the administrator of Nan Commandery under Shu Han, surrendered to the Eastern Wu forces invading Jing Province. His defection directly led to the fall of the regional base and the subsequent death of the revered general Guan Yu. Upon learning of his brother's devastating betrayal, Mi Zhu, a high-ranking official and elder brother to Mi Fang, bound himself with ropes and voluntarily presented himself to Emperor Liu Bei, begging for severe punishment under the ancient principle of familial guilt. Though deeply grieved by Guan Yu's loss, Liu Bei personally untied Mi Zhu, absolving him of any blame, declaring that a brother's crime should not extend to the sibling. This case exemplifies Confucian tensions between collective family responsibility and individual merit-based loyalty in the Shu Han regime.

Liu Bei acquitted Mi Zhu of all charges, explicitly rejecting the notion of guilt by association. He personally removed the ropes, reaffirmed Mi Zhu's position and honor, and publicly declared that the sins of the younger brother should not be borne by the elder. Mi Zhu died of shame and illness roughly a year later.

The central dispute revolved around the application of the legal principle of yuan zuo (collective family punishment). The core question was whether Mi Zhu, as Mi Fang's brother, should be executed for his sibling's treason, despite Mi Zhu's proven loyalty, high status, and lack of complicity in the defection that led to Guan Yu's death.

The case reinforced the Confucian ideal of a merciful and discerning ruler in Liu Bei, contrasting sharply with the rigid legalist application of collective punishment. It highlighted the practical dilemma in state-building between upholding strict laws for deterrence and maintaining the loyalty of key aristocratic supporters. Mi Zhu's gesture set a moral benchmark for personal accountability, while his subsequent death from shame underscored the immense social and psychological weight of familial dishonor in ancient Chinese elite culture.
