About Zhuge Liang's "Famous Sayings and Stories":
"Three cobblers are as good as Zhuge Liang": This proverb comes from the countryside of Jiangnan, "Three cobblers, they make up." "Pig Leather Beam"; "Pig Leather Beam" refers to the old days, in order to make the shoes strong and beautiful, two vertical beams with pigskin edges were inlaid on the uppers (there are still such beams on the shoes of monks today). A poor cobbler can't do it alone. For such a high-skilled job, people used the term "three stooges to make a pig leather beam" to ridicule stupid people. "Pig leather beam" sounds like "Zhuge Liang", so the saying was misrepresented.
“Zhuge Liang pays filial piety—pretending”: In the Romance of the Three Kingdoms, Zhuge Liang went to mourn Zhou Yu after he was so angry that he went to mourn Zhou Yu. On the surface, Zhuge Liang was very sad and grieved, but inwardly he was very proud, but he had to mourn on behalf of Liu Bei and protect Sun Yat-sen. Liu Lianmeng is just pretending to be a little bit to deceive others, but generally speaking, he is pretending to be sincere.
Zhou Yu was very jealous of Zhuge Liang's talents. One day when Zhou Yu was discussing military affairs, he asked Zhuge Liang to rush to make 100,000 arrows. Zhuge Liang promised to build it in three days and issued a military order. Zhuge Liang later asked Lu Su to help him borrow ships, sergeants and straw handles. On the third day, Zhuge Liang asked Lu Su to go with him to get the arrows. On this day, the sky was filled with heavy fog, and it was difficult to see anyone on the other side. Before daybreak, Zhuge Liang ordered the ship to be sailed and had the sergeants beating drums and shouting. Cao Cao just asked the crossbowmen to shoot arrows at the incoming ship. Both sides of the boat were filled with arrows. Zhuge Liang ordered the army to return, but by this time it was too late for Cao Cao to pursue him. 100,000 arrows were "borrowed". When Zhou Yu learned about borrowing arrows, he sighed: I am really not as good as him!
Zhuge Liang's empty city plan---turning danger into safety: Zhuge Liang lost the street pavilion because of the wrong use of horses. Wei general Sima Yi took advantage of the situation and led an army of 150,000 to swarm towards the west city where Zhuge Liang was located. At that time, Zhuge Liang had no generals around him and only 2,500 soldiers in the city. Everyone was shocked when they heard the news that Sima Yi was coming with his troops. Zhuge Liang said to everyone: "Don't panic, everyone. I can teach Sima Yi to retreat with a little strategy." Zhuge Liang sent an order to hide all the flags and asked the soldiers to open the four city gates. Zhuge Liang led two little book boys and a harp, sat down on the tower and started playing the harp. After Sima Yi looked at it, he said: "Zhuge Liang has been cautious in his life and never took risks. Now that the city gate is wide open, there must be an ambush inside. If our army enters, they will fall into their trap. It is better to retreat quickly!" So all the soldiers and horses were gathered. Backed away. From this story, later generations summarized the saying "Kong Ming's strategy of empty city - turning danger into safety", which refers to a clever strategy of concealing emptiness and deceiving the opponent in a critical situation.
