In the Romance of the Three Kingdoms, Zhuge Liang cleverly set up an empty city plan. What role does music play?

Music also played an important role in the story of Zhuge Liang's clever plan in The Romance of the Three Kingdoms. At that time, Sima Yi led an army of 6.5438+0.5 million to attack the city in two ways. Zhuge Liang didn't have a general with him, only a few civil servants and 2,500 sergeants. In order to stabilize the morale of the army, he calmly entered the city and plucked the strings, showing a natural and unrestrained leisurely attitude. The soldiers around him listened to the powerful music melody and watched the coach play the piano leisurely, and the nervous mood relaxed immediately. Sima Yi carefully distinguished the music, and her voice was slow, as slow as flying, as light as fallen leaves, and there was no sign of nervousness and panic. She suspected that she was cheating and hurried back.
