Stratagem No. 31 第三十一计 Desperate stratagems (败战计)
The beauty trap
Literal
The beauty stratagem.
When you cannot break a strong army, work on the judgement and the appetites of the person who commands it.
Source line
兵强者，攻其将；兵智者，伐其情。将弱兵颓，其势自萎。利用御寇，顺相保也。
Traditional 兵強者，攻其將；兵智者，伐其情。將弱兵頹，其勢自萎。利用御寇，順相保也。
If their army is strong, strike at the general; if the general is clever, sap his feelings. When the general weakens and the troops go slack, the momentum withers of itself. It pays to use this to hold off raiders; by staying in right relation the two sides protect each other. The line is from the hexagram Jian (Gradual Progress).

The closing sentence is the Image on the third line of Jian (Gradual Progress): resist what raids you, and keep the relationship on terms that protect your own side. Applied here, you do not smash a strong army; you soften the person who makes it one thing.

Meaning
The beauty trap means that a strong army is attacked through its general, and a clever general is attacked through his feelings. The classical line does not mention women. It mentions judgement, appetite, and the slackness that follows when a commander stops being a commander. Troops do not have to be defeated in the field if the person who holds them together has gone soft, sleepy, or ridiculous to his own officers. The momentum, the text says, withers of itself.
The commentary ranks the gifts you can send a stronger enemy. Land, as the six states sent Qin, is the worst, because it feeds his strength. Silk and cash, as the Song sent the Liao and the Jin, is the next worst, because it feeds his treasury. A person sent to please him is, in the compiler’s view, the gift that eats the man rather than the map: it idles his will, wears his body, and gives his own subordinates a grievance. The pattern underneath is older and wider than the example. Anything that captures the commander’s attention, and turns it off the army, is the knife.
The story
Goujian, Fuchai, and Xi Shi 越王勾践
Mixed
After his defeat in 494 BC, Goujian of Yue submitted in person to Fuchai of Wu. The Shiji’s account is political and harsh. He served in Wu, he came home, he nursed the grudge with the famous gall by his seat, and he listened to Fan Li and Wen Zhong. He sent gifts and attendants. He waited while Fuchai grew fond of expeditions, of the north, of the role of a hegemon, and while Wu’s best chances were spent away from Yue. In 473 BC Yue destroyed Wu. Fuchai took his own life. Sima Qian tells that arc without a heroine. He tells a king who was softened, and a smaller state that had the patience to let him soften.
The woman Xi Shi enters in a later book. The Wu Yue chunqiu, an Eastern Han narrative, gives her a name, a training, and Fan Li as the man who presents her, along with treasures, so that Fuchai’s attention will leave the government. That is the story the stratagem commentary repeats, and it is the story almost everyone means. Treat the submission, the return, and the fall of Wu in 473 as history. Treat the named beauty as traditional literature built on that history. The stratagem does not require her. It requires a commander whose feelings can be led off the road his army still needs him to walk.
Goujian’s submission after 494 BC and the destruction of Wu in 473 BC are in Sima Qian’s Shiji, chapter 41, while Xi Shi’s mission is told in the Wu Yue chunqiu, an Eastern Han work, and not in that chapter of the Shiji.

Myth check
Often reduced to a trick for using women, and often attributed to Sun Tzu, the classical line never mentions women: it says strike the general and sap his feelings. Xi Shi is not in the Art of War and not in the Shiji’s main account of Goujian; the fall of Wu is history, and her mission is later literature.
Modern application
A stronger party in a negotiation is rarely moved by a worse argument. He is moved by a distraction that flatters the person and annoys his own side: a prestige project, a public friendship, a concession aimed at his vanity rather than at the deal. The stratagem’s ranking is a warning to the sender as much as a trick. Giving land, or the modern equivalent, equity and exclusive rights, feeds him. A distraction only works if it pulls him off the work and leaves your own purpose intact.
Inside an organisation the same pattern is a star hire, or a leader, whose calendar fills with the pleasures of the role while the operation slackens and the deputies grow resentful. You do not have to plan that outcome to recognise it. The defence is structural. Decisions that matter should not live in one person’s evenings. A commander who can be captured by a feeling is a single point of failure, which is all this stratagem needs.
Takeaways
- If you cannot break the force, study the commander.
- Do not pay a rival in land or exclusive rights.
- Keep vital decisions off one person’s moods.
How to counter it
Watch a leader whose time, flattery, and private pleasures are being supplied by the other side, especially when his own deputies have started to resent it, and move the important decisions into a group that still has to live with the outcome. Charm aimed at one desk is a campaign.
Questions
What is the beauty trap in the 36 stratagems?
It is the plan, when an army is too strong to fight, of weakening the general who holds it together. The classical line says: if their soldiers are strong, strike the general; if the general is clever, sap his feelings. The commentary prefers a beautiful companion to gifts of land or money, because land and money feed him. The pattern is any capture of the commander’s attention.
Was Xi Shi a real person?
Goujian of Yue really submitted to Fuchai of Wu after 494 BC and destroyed Wu in 473 BC. That is Sima Qian. The Shiji tells of gifts, service, and a king who went soft. It does not tell Xi Shi’s story. Her name, her training, and Fan Li’s presenting her come from the Wu Yue chunqiu, written in the Eastern Han. She is traditional literature over a real war.
