Zhuge Liang set up an empty city plan and let 4 soldiers sweep the floor at the door? Sima Yi understood on the spot
Introduction: The history of the three kingdoms is full of wars, and various classic battles are emerging in an endless stream. At the Battle of Guandu, Cao Cao completely annihilated Yuan Shao's 200,000 troops with 40,000 troops; at the Battle of Chibi, Liu Sun's army was only 50,000 people, and cao Cao's 800,000 troops were defeated; at the Battle of Yiling, the Wu army was only 40,000 people, and seized a few opportunities to burn 200,000 Shu troops to ashes. But to say that the most wonderful thing is the empty city plan, at that time Zhuge Liang only had 3,000 old, weak and disabled soldiers and civilian officials, and there were 100,000 troops led by Sima Yi under the city, instead of attacking the city, he actually chose to retreat. One detail worth noting is why Zhuge Liang let 4 soldiers sweep the floor at the door at that time? What was the reason for Sima Yi's retreat? Let's move on.
Things have to start from the first Northern Expedition of the Shu Han Dynasty, after several years of cultivation and recuperation, and Zhuge Liang also perfectly resolved the rebellion in South Central, and was joined by the foreign army in South Central. At this time, he took advantage of the change of commander of the western front of the Wei state to show Liu Chan the stakes and then asked for the Northern Expedition, and Liu Chan naturally agreed to this plan, rewarding the three armies and personally sending Zhuge Liang out of the city. On the battlefield, Zhuge Liang attacked the three counties in the northwest with Zhao Yun as his left wing, and with The Young Zhuang faction Ma Mo as the right wing, he was responsible for guarding the street pavilion to protect the safety of Zhao Yun's army, and he himself took civilian officials and old and weak soldiers to sit in the command of the Chinese army.
Zhao Yun was victorious in the initial battle, and completed the task with lightning speed, and Sima Yi, who learned of the loss of the city, quickly led 100,000 troops to the rescue. At that time, ma Mo was against The Veteran General of the State of Wei, Zhang Guo, who did not listen to advice and privately led his troops up the mountain, and Zhang Guo sent troops to besiege the Shu army and finally succeeded in taking the street pavilion. Zhuge Liang, who had lost the street pavilion, was immediately exposed to the Wei army and had no choice but to retreat to the western city, and Sima Yi's leaders chased after him with the slogan of capturing Zhuge Liang alive.
Seeing that the 100,000 Wei troops would soon arrive, Zhuge Liang immediately put up an empty city plan after some consideration, calmly played the piano in the city, and ordered 4 soldiers to pretend to be civilians to sweep the floor at the door. With 100,000 Wei soldiers approaching the city, Sima Yi saw this abnormal situation and did not directly attack the city, but instead rode his horse to find out. He watched the 4 people at the door diligently sweeping the floor, and Zhuge Liang, who played the piano on the city wall, smiled at him from time to time, and he suddenly understood something! So he shouted that there was an ambush in the city, and led the army to retreat fifty miles. The Generals of the Wei Army saw this and complained one after another, believing that Sima Yi was too timid and that the matter had been discussed within the army.
Later, Sima Zhao couldn't bear it, and took advantage of the fact that no one was around to ask Sima Yi the reason for his retreat. It turned out that at that time, Sima Yi already knew that there was no one in the city, as long as he sent troops to attack the city, he would definitely be able to capture Zhuge Liang alive, but such a result would only lead to the sima family being killed, and Zhuge Liang deliberately let 4 people sweep the floor and already implied that he was "dead". Because Sima Yi had been a civilian leader, if he had obtained this immortal merit in defeating the Shu army, he would have made a great contribution to the Lord. In history, the fate of the generals who have achieved great merit can be described as very miserable, such as Fan Li and Wen Zhong in the Warring States period, and the same is true of Han Xin in the Western Han Dynasty. For the sake of the continuation of the Sima family, he could only do this. When Sima Zhao heard this, he suddenly realized that he also deeply admired Sima Yi's wisdom.
Conclusion: What was the result? Zhuge Liang retrieved a life, and Sima Yi had nothing to lose. Moreover, the subsequent continuous operations not only allowed Sima Yi to obtain a large number of military merits, but also completely grasped the military power. At that time, he had become a popular person, taking advantage of the negligence of political enemies, he successfully seized the actual rule of the State of Wei in one fell swoop and became the final winner of the Three Kingdoms period.
