Yang Xiu’s execution, prompted by the ambiguous password “Chicken gristle,” turns an indirect reading of Cao Cao’s intentions into a capital offense. The password is only the immediate trigger: the narrative connects the killing to accumulated suspicion over Yang Xiu’s clever interpretations, his friendship with Cao Zhi, and his involvement in the contest over Cao Cao’s heir. Cao Cao later recognizes the wisdom of Yang Xiu’s advice and has his body exhumed for burial with full military honours, giving the execution a stark reversal without undoing its consequences.

Circumstances of the Password

During a campaign marked by danger and uncertainty, Cao Cao receives a bowl of chicken soup containing a piece of gristle. Asked for the password for the night, he answers, “Chicken gristle.” Yang Xiu, Cao Cao’s primary secretary, hears the password and tells his men to pack for the return journey. When Xiahou Dun asks why, Yang Xiu explains his interpretation: gristle has no meat, though it adds flavour; likewise, the army can neither advance nor withdraw without risking disadvantage, so it has no option but to go home.

Yang Xiu’s reading treats a brief, unexplained password as a compressed statement about the campaign’s prospects. His interpretation is sufficiently persuasive to prompt preparations across the camp. What Cao Cao meant by the password is not presented as an explicit order to withdraw; instead, the episode turns on the gap between Cao Cao’s words and the inference his secretary draws from them.

Immediate Cause and Earlier Mistrust

When Cao Cao discovers that the troops are packing, he becomes furious, accuses Yang Xiu of making up stories, and orders him executed. The password supplies the immediate occasion, but the account stresses that Cao Cao and Yang Xiu have a longer history of misunderstanding. Yang Xiu has repeatedly interpreted characters written by Cao Cao in unexpected ways. Cao Cao is fascinated by this ability, yet also annoyed by it: the same intellectual acuity that attracts his attention unsettles him.

The execution is therefore not portrayed as a response to an isolated joke or a single mistaken command. It is the culmination of suspicion that has gathered around Yang Xiu’s habit of finding meanings beyond the surface of Cao Cao’s words. In the password episode, that interpretive skill becomes consequential at precisely the moment when military uncertainty makes the army’s next move sensitive.

The Succession Dispute

Cao Cao’s distrust is also tied to Yang Xiu’s friendship with Cao Zhi, Cao Cao’s third son, during the struggle to determine the heir. Cao Pi, the eldest son, sought help from the senior adviser Wu Zhi. To keep the visit from Cao Cao’s notice, a plan was made to conceal Wu Zhi in a large container used for storing silk and bring him to Cao Pi’s quarters.

Yang Xiu informed Cao Cao of the plan. Cao Pi learned that it had been exposed, cancelled Wu Zhi’s visit, and filled the container with silk rolls instead. When Cao Cao’s investigators examined it, they found only the silk and reported that result. From then on, Cao Cao believed Yang Xiu intended to harm his eldest son. The episode deepened mistrust within an already charged succession struggle: Yang Xiu’s actions were understood through the suspicion that he was aligned against Cao Pi, while his friendship with Cao Zhi gave that suspicion a political context.

Execution and Reversal

The account gathers these misunderstandings, mistrust, and suspicions into Cao Cao’s growing desire to be rid of Yang Xiu. The chicken-gristle password becomes the excuse that makes the decision actionable. Yang Xiu is thirty-four when he is executed, and his head is displayed at the camp entrance as a warning. The stated circumstances make the severity of the outcome striking: an interpretation that others accept as a practical conclusion about the campaign is treated by Cao Cao as intolerable insubordination, against the background of personal and political distrust.

The next morning Cao Cao rides into battle. After Ma Chao attacks from behind, Wei Yan also attacks Cao Cao’s force and knocks him from his horse with an arrow. Pang De’s charge prevents Wei Yan from killing him, and Cao Cao is carried back to camp. During treatment, Cao Cao recalls Yang Xiu’s view that the army should return home and recognizes that the advice was wise. He orders Yang Xiu’s body exhumed and gives him full military honours at burial. The recognition comes only after the execution: it restores honour to Yang Xiu’s memory, but cannot reverse the killing that Cao Cao had authorized.

Narrative Significance

The incident brings together military judgment, interpretation, and court politics. Yang Xiu reads the password as a clue to the campaign’s limits; the later course of events makes that judgment appear sound. Yet the killing is shaped not only by the immediate question of whether to advance or retreat, but by Cao Cao’s accumulated resentment of Yang Xiu’s cleverness and his concern about the succession struggle. The episode’s movement from password to execution and then to posthumous recognition gives the reversal its force: Cao Cao first treats Yang Xiu’s inference as a threat, then acknowledges its value when events press the same conclusion upon him.
