Show friendship and paralyze the enemy; A hidden plot, a hidden murder. In order to ensure the victory of the war, we must make full preparations before the war and wait for an opportunity to sneak attack the enemy without being noticed by the enemy. This is a tactic of being rigid inside and soft outside.

This plan comes from the poem Beyond the Limit by Bai Juyi, a poet in the Tang Dynasty: "Let's put out the anger in the fire and stop sharpening our knives. It is better to drink in Tao Tao and get drunk. " Confucius said, "Clever words make the color so fresh." That kind of rhetoric, pretending to be a hypocritical face, rarely pays attention to benevolence and morality. The ancient art of war has long warned: Never believe each other's sweet words, but beware of each other's hidden dangers. This kind of plan is used in military, political, diplomatic and other aspects of camouflage, and sometimes it can make the other side unprepared and regret it.

A concrete example of a battle

During the Three Kingdoms period, Guan Yu was guarding Jingzhou, and Sun Quan always had the idea of taking Jingzhou. Sun Quan sent Lu Xun, a young general who was unknown at that time, to station in Lukou.

Before Lu Xun took office, he decided to prepare for war with Guan Yu. After Lu Xun arrived in Lukou, he wrote to Guan Yu to show weakness, saying that he was too young to be a scholar, so he asked Guan Yu for advice.

After reading this letter, Guan Yu relaxed his vigilance against Wu Dong and transferred most of his troops from the defenders defending Jingzhou to attack Cao Cao's army.

Lu Xun secretly sent someone to tip off Cao Cao and agreed that both sides would act together to attack Guan Yu. Guan Yu was careless about Jingzhou and eventually lost to Maicheng.
