The political opposition between Cao Cao and Liu Bei

The political opposition between Cao Cao and Liu Bei gives the novel a personal frame for the struggle over who may claim to act in the Han dynasty’s name. Cao Cao holds the emperor and the machinery of the court, presenting himself as the dynasty’s protector; Liu Bei claims imperial descent and the duty to oppose ministers who have usurped the emperor’s authority. Their relationship consequently shifts between hospitality, mutual calculation, secret resistance, and armed conflict. The contrast is not merely between two rival commanders: it exposes how the same language of service to the Han can support competing claims to legitimate power.

Competing claims to authority

Cao Cao’s position depends on his command of imperial institutions. When advisers urge him to kill Liu Bei at a moment when Liu Bei is vulnerable, one argues that Cao Cao has promised to support the legitimate Han dynasty and free the people from fear. Killing a respected hero would make Cao Cao notorious and deter virtuous men from serving him. Cao Cao accepts this counsel and instead gives Liu Bei additional troops as a sign of friendship. Political prudence and public reputation thus restrain an immediate attack, without ending the underlying rivalry.

The court later makes Liu Bei’s lineage explicit: after returning from the imperial hunt, the emperor names him imperial uncle and takes him into his confidence. The recognition gives Liu Bei a position tied to the ruling house, even as Cao Cao’s influence over the emperor continues to grow. Cao Cao’s method is gradual encroachment on imperial powers, not an immediate declaration that he will take the throne. The opposition therefore develops inside an unstable arrangement: Liu Bei has an imperial identity recognized by the emperor, while Cao Cao controls the setting in which that identity must operate.

Kong Ming gives the rivalry a strategic explanation when Liu Bei seeks his counsel. In Kong Ming’s account, Cao Cao has overcome Yuan Shao through cunning, commands a vast army, and controls the emperor, drawing many nobles to his side. Liu Bei cannot simply confront that power on equal terms. The analysis places their political disagreement within the broader division of the realm: Cao Cao is the formidable northern power, while Liu Bei must build a position from which resistance can become possible.

Hospitality, suspicion, and concealment

The two men’s public association conceals their growing mistrust. When Cao Cao’s adviser again argues that Liu Bei should be spared, the reason is not personal reconciliation but the political cost of killing a celebrated figure. Cao Cao can treat Liu Bei as a guest and offer him support while remaining a powerful rival whose court Liu Bei experiences as a place of constraint.

That danger becomes sharper after the imperial hunt. Cao Cao brings the emperor on a hunt that he himself has arranged, with his own men staffing the event. When the emperor misses a stag and Cao Cao brings it down with the imperial bow, the courtiers mistake the shot for the emperor’s and applaud him. Cao Cao accepts the praise instead of correcting them; the courtiers understand the implication and grow alarmed. Guan Yu prepares to attack, but Liu Bei signals him to stop. Liu Bei’s restraint is tactical: an attack against Cao Cao’s men would fail under the circumstances. Cao Cao later congratulates the emperor while keeping the imperial bow over his own shoulder, turning the incident into a visible demonstration of the power he exercises around the throne.

The emperor subsequently recognizes Liu Bei as an imperial relative and confidant. Dong Cheng, who seeks allies against Cao Cao, hesitates to approach him because Liu Bei is also a close associate of Cao Cao. Liu Bei initially appears to defend Cao Cao when Dong Cheng brings up Guan Yu’s conduct at the hunt. Only after the two men gradually disclose their suspicions does Liu Bei reveal that he has been testing Dong Cheng, fearing that the approach might itself be a loyalty test arranged by Cao Cao. He then signs the white silk pledge to join the effort to overthrow Cao Cao. His commitment is secret, and he avoids attracting notice by keeping to work in his garden.

The heroes’ garden and the choice to leave

Cao Cao’s conversation with Liu Bei over a dragon-shaped cloud makes their rivalry personal as well as political. Cao Cao describes the dragon as able to rise into the sky or disappear into the depths, then compares such a figure to a man who aspires to rule the world. He asks Liu Bei to name the age’s greatest heroes. Liu Bei answers cautiously, naming Yuan Shu and others, but Cao Cao dismisses these candidates and finally declares that only he and Liu Bei are heroes alive today. Liu Bei is so alarmed that he drops his chopsticks. The exchange recognizes Liu Bei as a potential rival even as it places him under Cao Cao’s scrutiny.

Zhang Fei and Guan Yu arrive after hearing that Liu Bei has been summoned, their hands on their sword hilts. To avoid provoking Cao Cao’s suspicion, they claim that they have come to perform a sword dance. The interruption underscores how much danger surrounds Liu Bei’s double position: trusted associate in appearance, committed opponent in secret. When the news arrives that Yuan Shao has defeated Gongsun Zan, Liu Bei is saddened by his friend’s death, while Cao Cao weighs the increased threat from Yuan Shao and the possible union of Yuan Shao with Yuan Shu and the imperial seal.

Liu Bei volunteers to lead an army against Yuan Shu, receiving an imperial commission and setting out with fifty thousand soldiers. He tells Dong Cheng that he will not forget the emperor’s command. To his brothers, he describes Cao Cao’s court as a cage from which he has escaped. His departure is not yet open war against Cao Cao, but it gives Liu Bei a way out of an atmosphere in which every word and allegiance may be watched, and creates room for him to act independently.

From conspiracy to open battle

Cao Cao’s distrust grows as Liu Bei gains popularity. After Liu Bei defeats Yuan Shu and reports the outcome to the emperor, Cao Cao orders Che Zhou, the governor of Xuzhou, to ambush him on his return. Forewarned, Liu Bei and his brothers turn the plan against Che Zhou and enter Xuzhou. Zhang Fei’s killing of Che Zhou’s family alarms Liu Bei, who expects Cao Cao to retaliate. The episode shows the rivalry moving beyond guarded court politics: Liu Bei’s growing base of power and Cao Cao’s effort to contain it now produce direct violence and consequences for their followers.

After the imperial conspiracy is discovered, Cao Cao has the emperor’s pregnant concubine, Dong Cheng’s sister, killed despite the emperor’s plea and the empress’s offer to take her place. Cao Cao then seals off the imperial family and posts three thousand of his own guards around the emperor. Liu Bei is one of only two survivors from the original group of conspirators, alongside Ma Teng. Cao Cao treats Liu Bei’s army as a more immediate danger and sends two hundred thousand soldiers to capture him and take Xuzhou. Liu Bei seeks assistance from Yuan Shao, but receives none; forced to respond with his own limited options, he faces a campaign that makes the secret opposition an explicit military confrontation.

At Rang Mountain, Cao Cao appeals to their former personal bond, reminding Liu Bei that he had once been his guest and had been treated with honour. Liu Bei answers that Cao Cao is a traitor to the Han and says that, as a man of imperial blood, he has been ordered to crush him; he then reads aloud from the secret belt decree. Cao Cao orders an attack. Guan Yu and Zhang Fei lead the charge, and Cao Cao’s tired troops retreat to their fortified camp. Liu Bei’s success is short-lived: Cao Cao’s forces continue to threaten him from several directions, and Liu Bei’s army suffers severe losses before he escapes. The battle makes the divide in their political language unmistakable, but its uncertain outcome also shows the disparity in power that has shaped Liu Bei’s choices from the beginning.

A rivalry shaped by the novel’s historical layers

The opposition is part of a much larger account of the collapse of the Han and the rise of three competing kingdoms. The novel draws on recorded events but, as its introduction explains, also brings together the dramatic traditions of oral storytelling and theatre with the work of a later novelist. Poems and theatrical patterns help turn political history into a contest between memorable figures. Cao Cao and Liu Bei’s rivalry gives that contest a human focus: institutional power and personal ambition meet claims of imperial descent, loyalty, and public virtue.

The relationship is therefore more complex than a steady progression from friendship to hatred. Cao Cao can spare and support Liu Bei for political reasons, while Liu Bei can accept a commission and remain in Cao Cao’s orbit without surrendering his loyalty to the Han. Yet the imperial hunt, the secret pledge, the attempt to trap Liu Bei in Xuzhou, and their encounter at Rang Mountain steadily narrow the space for accommodation. Their rivalry endures because both men’s actions are entangled with the question of who controls the emperor and who may credibly claim to defend the dynasty.
