The only record is "Liang Fu Yin".

Chapter 95 of "Romance of the Three Kingdoms": Ma Su refused to admonish and lost his pavilion in the street. Marquis Wu played the zither and retreated to Zhongda.

Kong Ming's allocation has been decided, and he will first lead five thousand soldiers to retreat to Xicheng County to carry grain and grass. Suddenly Pegasus reported more than ten times and said: "Sima Yi has led an army of 150,000 people, and the west city is swarming!" At that time, Kongming had no other generals around him, only a group of civilian officials. Half of the 5,000 soldiers he had led had been sent to transport grain and grass first. There were only 2,500 troops left in the city. When all the officials heard the news, they all became pale. When Kong Ming climbed up the city to look at it, he saw that the dust was soaring into the sky. Wei soldiers divided into two groups to watch Xicheng County coming to kill them. Kongming sent an order, "Hide all the banners and flags; all armies will guard the city. If anyone comes in or out rashly, or speaks loudly, behead him! Open the four gates, and use twenty sergeants at each gate to pretend to be civilians." "Sweep the streets. If the Wei soldiers arrive, don't move without permission. I have my own plan." Kong Ming put on a crane cloak and a silk scarf, and led two boys to sit on the railing in front of the enemy tower and burn incense. Play the piano.

But he said that Sima Yi's former military sentry arrived at the city. Seeing this appearance, they did not dare to enter and reported to Sima Yi urgently. Yi laughed and didn't believe it, so he stopped the three armies and watched them from a distance from Pegasus. Sure enough, I saw Kong Ming sitting on the tower, smiling broadly, burning incense and playing the piano. There is a boy on the left, holding a sword in his hand; there is a boy on the right, holding a mulberry tail. Inside and outside the city gate, there were more than 20 common people, lowering their heads and sweeping as if there was no one around. Yi looked suspicious, so he went to the middle army, taught the rear army to be the front army, and the front army to be the rear army, and retreated looking at the north mountain road. The second son Sima Zhao asked: "Is it because Zhuge Liang has no troops and is acting like this? Why did my father retreat?" Yi said: "Liang was cautious in his life and never took risks. If we open the city gate now, there will be an ambush. If our soldiers advance, This is his plan. Did you know that we should retreat quickly?" So all the soldiers retreated. When Kong Ming saw the Wei army retreating, he put his hands on his hands and smiled. All the officials were shocked and asked Kong Ming: "Sima Yi is a famous general of Wei. Now he has commanded 150,000 elite troops here. When he saw the prime minister, he quickly retreated. Why?" Kong Ming said: "This man expected me to be cautious in my life. He must be careful." Don't take risks. Seeing this, I suspect there is an ambush, so I retreat. I am not taking risks because I have no choice. I have ordered Xing and Bao to wait there." Everyone was shocked and said: "The prime minister's plan is unpredictable. If someone sees it, he will abandon the city and leave." Kongming said: "We only have 2,500 soldiers. If we abandon the city and leave, we will surely I can't escape far away. Is it possible to be captured by Sima Yi?" Later generations wrote a poem that said: "When Zhugexi City retreated from the enemy, 150,000 people returned to the horse place, and the natives still doubt it." After saying this, he clapped his hands and laughed, saying: "If I were Sima Yi, I would not be able to retreat." Then he ordered the people in Xicheng to be educated and follow the army into Hanzhong; Sima Yi will definitely come back. So Kongming left Xicheng and looked at Hanzhong. Officials, soldiers and civilians from Tianshui, Anding and Nan'an counties came one after another.

Chen Shou's "Three Kingdoms: Zhuge Liang's Biography" records: "Xuanzu, Liang worked hard to cultivate Longmu, so that he could chant for Liang's father." ... To the west of the house, there is a mountain and water. Kong Ming often climbed it and played "Liang Fu's Yin" on the harp, so the mountain was named Leshan. In the first volume of "Classic", Zhuge Liang wrote about the beginning of Qin making and the sound of the seven strings, and the meaning of the thirteen emblems. "Xie Xiyi's "Qin Lun" also records: "Zhuge Liang wrote "Liang Fu Yin" "Yi Di Zhi". Records: "There is a stone harp in the Wuhou Temple in Dingjun Mountain. When you brush it, the sound is very clear. It is said that it was left by Wuhou." From the above records, it is enough to see that Zhuge Liang has a very comprehensive cultivation and high art in music. Achievement. He is good at vocal music - he can sing; he is also good at instrumental music - he is good at playing the harp; at the same time, he also creates music and lyrics, and can also make musical instruments - making lyres and stone harps. Not only that, he also wrote a monograph on music theory - "Qin Jing".
