Empty city plan? In fact, it is also one of the 36 schemes. At the earliest time, people learned about the empty city plan from Zhuge Liang. At that time, Sima Yi led Wei Jun to attack the Jieting area of Shu, but Ma Su appointed by Zhuge Liang lost the Jieting because of carelessness, and Sima Yi and others went to the west of the gate. However, at this time, there was no army in the city that could resist Sima Yi. In desperation, Zhuge Liang launched an "empty city plan". Zhuge Liang ordered the soldiers to deliberately open the city gate, and then ran to the rostrum to play the piano, giving Sima Yi a leisurely illusion.
Sima Yi became suspicious when he saw Zhuge Liang's every move, so he felt that there was an army waiting for him in the city. Finally, Sima Yi chose to retreat for the sake of safety. Although this is only a story of deifying Zhuge Liang, we can also see the role of strategy in the war. Another example is something familiar to people? Tian Ji horse racing? At that time, Tian Ji, the general of Qi, wanted to race horses with other constantly chauffeured horses, but Tian Ji's horses were not as good as those of other constantly chauffeured horses.
At this moment, Sun Bin gave Tian Ji a good idea. Sun Bin suggested that Tian Ji divide horses into three categories: superior, medium and inferior. Others send excellent horses, Tian Ji sends inferior horses, Tian Ji sends excellent horses, others send inferior horses, and Tian Ji sends inferior horses. In this way, Tian Ji can win two more games after three games, and then win again. Although it is only a small horse race, it also sees the strategy.
