The Case of Cui Zhu Marrying Tang Jiang and Duke Zhuang of Qi's Adultery

Cui Zhu, a powerful minister of Qi, married the widow Tang Jiang. Duke Zhuang of Qi committed adultery with her and even publicly humiliated Cui Zhu by taking his hat and giving it to another. Enraged, Cui Zhu feigned illness and laid an ambush at his residence. When the duke came to visit, Cui Zhu's followers killed him. After the assassination, Cui Zhu installed Duke Jing of Qi and took power as chancellor. The grand historian recorded in the annals: "Cui Zhu assassinated his lord." Cui Zhu executed him; the historian's younger brother continued the same record and was also killed. A third brother wrote it again, and Cui Zhu, realizing their resolve, let him go. Another historian from the south was seen carrying bamboo slips, ready to record the truth, but turned back upon learning it had been recorded. Yan Ying, a senior official, mourned the dead duke according to ritual, balancing loyalty and survival.

There was no formal judicial trial. Cui Zhu successfully eliminated Duke Zhuang and installed Duke Jing, becoming the de facto ruler. Two years later, internal strife orchestrated by Qing Feng led to the collapse of the Cui clan; Cui Zhu committed suicide. The grand historians' relentless commitment ensured the truthful record survived, and their account was preserved in the official annals.

Whether Cui Zhu's killing of the duke was a justifiable revenge for personal dishonor or an act of usurpation and regicide. The tension between a ruler's moral transgressions and a subject's duty of loyalty. The conflict between political power and the historiographers' integrity, as Cui Zhu attempted to suppress the truth through murder. Yan Ying's nuanced position on obligation to the state versus allegiance to a fallen ruler.

The case became a hallmark of moral and political disorder in the Spring and Autumn period, illustrating the collapse of reciprocal obligations between ruler and subject. The courage of the historians in facing death to record the truth became a timeless symbol of historiographical integrity, celebrated in Chinese culture. Confucius retained the entry "Cui Zhu assassinated his lord" in the "Spring and Autumn Annals", exemplifying the "praise and blame" principle in chronicles. The event served as a cautionary tale about the dangers of a ruler's personal depravity and the vengeance of dishonored ministers.
