The Case of Zhang Tang, a Man of Longxi, Who Cursed and Caned His Master

In Longxi Commandery during the Western Han Dynasty, a man named Zhang Tang committed a severe breach of Han social hierarchy and law by verbally abusing (mao li, 骂詈) and then physically striking his master with a staff (caning). Under Han statutes, particularly those governing the relationship between masters and servants or retainers, such an act by a subordinate against his lord constituted a grave felony. The local magistrate, bound by strict legal codes emphasizing filial piety and absolute obedience within the master-servant relationship, arrested Zhang Tang. The case was deemed so serious that it may have been submitted for review to the Commandant of Justice (Tingwei, 廷尉), as was customary for capital offenses, marking a direct confrontation between a bondsman and the entrenched patriarchal order sanctioned by Han law.

Zhang Tang was found guilty of the extremely serious combined offense of cursing and assaulting his master. In strict accordance with Han statutes, which prescribed death for a servant who struck his master, he was sentenced to public execution by beheading (Qishi, 弃市) in the marketplace, a punishment designed to humiliate the criminal and reinforce the absolute, inviolable nature of the master-servant hierarchy.

The central legal dispute lay in determining whether Zhang Tang's actions constituted the standard capital offense of "assaulting one's master" or the more egregious and symbolically charged crime of "Bu Dao" (不道, violation of the moral order), given the combined elements of verbal insult (mao li) and physical battery. The case also questioned the degree of intent and whether the master's own conduct, if any, might mitigate the punishment under the nuanced interpretations of Han judicial precedent.

The case served as a stark public reinforcement of the rigid Confucian-based social hierarchy that underpinned Han legal and social order. It was cited in legal commentaries and by officials as a quintessential example of the absolute prohibition against insubordination, demonstrating that the state would use its ultimate punitive power to protect the sanctity of the master's authority and the patriarchal family structure, thus deterring any challenge to the foundational principle of "li" (ritual propriety).
