After the Empty City Plan, Sima Yi and his son had a conversation rather than a famous quote.

The dialogue is as follows:

Sima Yi: "The clanking sound is like the waves crashing on the shore, the wind blowing the remaining clouds, and there seems to be millions of soldiers at the fingertips."

Sima Yi Zhao: "Father, why can't I hear it?"

Sima Yi: "Listen, it's like a mountain stream, crystal clear to the bottom. It can't be done by someone who has to be relaxed and happy. Zhuge Liang must be confident."

Sima Zhao: "Father, how can a few strings be so expressive?"

Sima Yi: "If the mind is disturbed, the sound will be noisy; if the mind is calm, the sound will be pure; if the heart is flustered, the sound will be wrong; if the state of mind is the sound, the sound will be pure." Qing. Listening to Zhuge Liang playing the piano is like watching his heart. I am honored to be a close friend of Zhuge Liang! I will order the rear team to retreat to Beishan."

Sima Zhao: "Why did my father retreat? ?"

Sima Yi: "You don't know that Zhuge has always been careful with his troops and has never taken any risks. Now that the city gate is wide open and there are no soldiers, there must be an ambush in the city. If you enter the city, you will definitely fall into his trap."

The story of the Empty City Strategy is taken from "The Romance of the Three Kingdoms", a story adapted by the author based on Pei Songzhi's annotation "Guo Chong's Three Things". It was later used in the Thirty-six Stratagems, which means that the situation is both false and true, and that the army is unstable. The tactic of doubting the enemy's strength by showing weakness is a kind of psychological warfare that creates suspicion within suspicion. It is mostly used in situations where oneself is weak and the enemy is strong.
