In The Art of War, the tenth of Sun Tzu’s twelve deceptive tactics is “feigning humility to encourage arrogance” (卑而骄之).
In this context, “humility” is not genuine weakness or submission; rather, it is a deliberate, calculated facade. The ultimate goal of this strategy is to project an illusion of inferiority to breed overconfidence in the enemy, lulling them into a state of complacency and underestimation. By doing so, a commander creates the perfect window of opportunity for a devastating, unexpected counterstrike.
The Rise of Modu and the Donghu’s Provocation
One of the most classic historical manifestations of this tactic is the campaign of Modu Chanyu, who annihilated the powerful Donghu confederation. In 209 BC, Modu assassinated his father and seized power as the Chanyu of the Xiongnu. At that time, the Donghu were exceptionally powerful and held the newly ascended Modu in contempt.
Exploiting Modu’s precarious hold on power, the Donghu King decided to test him. He sent an envoy demanding Modu’s prized “thousand-li horse.” When Modu asked his ministers for their opinion, they unanimously protested,
“The thousand-li horse is the treasure of the Xiongnu; we must not give it away.”
Modu, however, replied with calculated submission,
“How can I be so stingy as to deny a horse to a neighboring state?” He promptly handed over the magnificent steed.
The Ultimate Test of Humiliation
Emboldened by Modu’s apparent cowardice, the Donghu King escalated his demands. Some time later, he sent another envoy, this time demanding one of Modu’s beloved consort (Yanzhi). Outraged, Modu’s ministers clamored for war, declaring the Donghu’s demands utterly unreasonable. Yet, Modu maintained his facade, asking,
“How can I be so stingy as to deny a woman to a neighboring state?”
He then sent his cherished consort to the Donghu.
This ultimate act of feigned submission shattered whatever remaining respect the Donghu had for the Xiongnu. The Donghu King’s arrogance swelled to unprecedented heights, and he began to aggressively encroach upon Xiongnu territory to the west.
The Line in the Sand and the Decisive Strike
Between the two nations lay a vast, uninhabited buffer zone stretching over a thousand li, where both sides had established border outposts. The Donghu King sent yet another envoy, declaring that Modu was forbidden from entering the unclaimed land beyond the Xiongnu outposts, as the Donghu intended to claim it.
When Modu asked his ministers, some wavered, suggesting the abandoned land could be given away. At this moment, Modu’s true intentions were finally revealed. Enraged, he thundered, “Land is the very foundation of a state! How can we give it away?” He immediately executed the ministers who had advised surrender.
Modu mounted his horse and issued a ruthless decree: anyone who retreated in battle would be beheaded. Leading his highly disciplined forces, he launched a surprise eastern offensive against the Donghu.
The Price of Complacency
Because the Donghu had long underestimated the Xiongnu, they had completely neglected their defenses. When Modu’s army descended upon them, the Donghu were instantly routed. The Donghu King was killed, and the Xiongnu captured the Donghu people and seized their vast herds and wealth. Modu’s masterful application of feigned humility had successfully transformed his enemy’s arrogance into their ultimate destruction.
A Parallel of Deception: Sun Quan and Lu Xun vs. Guan Yu
Over a millennium later, this exact psychological blueprint was replicated in the Three Kingdoms period during the conquest of Jingzhou. The legendary Shu Han general Guan Yu was at the height of his power, launching a formidable northern campaign. Recognizing that a direct confrontation with Guan Yu’s elite forces would be disastrous, the Eastern Wu leadership, under Sun Quan, resorted to “feigning humility to encourage arrogance.”
To paralyze Guan Yu, Sun Quan took the initiative to propose a marriage alliance between his son and Guan Yu’s daughter to show sincere friendship. Even after being insulted and rejected by Guan Yu, Sun Quan showed no anger and volunteered to send troops to assist Guan Yu’s northern expedition.
The Eastern Wu commander Lü Meng, then feigned a severe illness and returned to the capital, replacing himself with the relatively unknown and untested young scholar, Lu Xun. Upon taking command, Lu Xun immediately initiated a masterful psychological campaign, writing a letter to Guan Yu dripping with sycophantic humility. Lu Xun professed his profound admiration for Guan Yu’s “majestic virtue” and assured the general that he would never dare to oppose him.
Completely deceived by this feigned weakness, Guan Yu lowered his guard and transferred the bulk of his Jingzhou garrison to the northern front. With Jingzhou left virtually undefended, Lü Meng immediately launched a surprise campaign, capturing the strategic cities and severing Guan Yu’s retreat. The legendary general was ultimately captured and executed.
In Summary
Whether on the steppes of ancient Mongolia or along the Yangtze River, the application of “feigning humility to encourage arrogance” proved devastatingly effective. Modu’s masterful application of feigned humility, much like Lu Xun’s sycophantic letter, successfully transformed the enemy’s arrogance into their ultimate destruction. In both cases, the victors understood that the most lethal weapon in warfare is not brute force, but the ability to manipulate the opponent’s ego, turning their overconfidence into a fatal vulnerability.
