Cao Cao sent troops to attack Liu Bei in Hanzhong, and was trapped at the border of the oblique valley. He wanted to join the army, but Ma Chao refused to stay. He wanted to withdraw his troops and return to Korea, but he was afraid of being laughed at by the Shu soldiers. He hesitated and met the chef with chicken soup. Cao Cao felt pregnant when he saw chicken ribs in the bowl. Is thoughtfully, Xia Houdun enter an item in an account, please night slogan. Cao Cao casually replied, "Chicken ribs! Chicken ribs! " Dunchuan ordered all officials to call it "chicken ribs!" Yang Xiu, the marching master, saw the word "chicken ribs" and taught the accompanying sergeant to pack up and prepare for the return trip. Someone told Xiahou Dun. Surprised, Dundon asked Yang Xiu to settle accounts and asked, "How do you pack things?" Yang Xiu said: "Judging from tonight's orders, we can know that Wang Wei will soon withdraw his troops and return home. Chicken ribs have no meat to eat. It's a pity to lose them. If we can't win the invasion now, withdrawing troops will be laughed at. It's no good here. It is better to go back as soon as possible. Wang Wei will definitely return to Korea tomorrow. So pack your luggage first, so as not to panic when you arrive. " Xia Houdun said, "You really know Wang Wei's heart!" Pack your luggage. So all the generals in the barracks have nothing they are not going back to. When Cao Cao learned about this situation, he summoned Yang Xiu to ask him, and Yang Xiu replied with the meaning of chicken ribs. Cao Cao was furious: "How dare you lie and make trouble!" He told the thugs to push Yang Xiu out and behead him and hang him outside Yuanmen. It turns out that Yang Xiu, with his own talent, was not bound by his own behavior, and repeatedly committed Cao Cao's taboo. Once, Cao Cao built a back garden. After the completion, Cao Cao went to watch and walked around the garden. When he left, he said nothing but wrote a word "live" on the garden door. The craftsmen didn't know what this meant, so they asked Yang Xiu. Yang Xiu said to the craftsmen, add movable type where the door is wide. The Prime Minister thinks that you have made the garden door too wide. The craftsmen suddenly realized and rebuilt the garden gate. Please ask Cao Cao for acceptance after completion. Cao Cao was overjoyed and asked, "Who knows me?" The left and right answers: "Thank you, Master Yang, for your advice!" Although on the surface, Cao Cao is good, but his heart is taboo. One day, someone in Saibei sent Cao Cao a box of delicate crispy cheese to please him. Cao Cao took a bite and suddenly had a brainwave. He wanted to test the intelligence of the civil servants and military commanders around him, so he wrote the word "one crisp" vertically on the crisp box and asked the special envoy to give it to the minister of civil and military affairs. The ministers were puzzled by this box of cakes and asked Yang Xiu for advice. When Yang Xiu saw the words on the box, he picked up the tableware and shared it with everyone. Everyone asked him, "How dare we eat Wang Wei's food?" Yang Xiu said: "It was Wang Wei who made us all crisp!" All the civil servants and military commanders present were surprised by Yang Xiu's intelligence. Later, Cao Cao asked why, and Xiu calmly replied, "How dare you disobey the orders of the Prime Minister?" Although Cao Cao likes to laugh, he hates Yang Xiu in his heart. Cao Cao is suspicious, afraid of being countered by others. He often tells his left and right, "I like killing people in my dreams. Whenever I fall asleep, don't go near! " One day, Cao Cao was sleeping in his tent and fell to the ground on purpose. A waiter panicked and covered it for him. Cao Cao immediately jumped up and drew his sword to kill him, and went to bed again. After sleeping for a long time, I got up, pretended to dream, and asked in surprise, "Who killed my bodyguard?" Everyone told the truth. Cao Cao wept bitterly and ordered him to be buried next to the waiter. People thought that Cao Cao really killed someone in his dream, but Yang Xiu saw through his intention. When he was buried, he pointed to the body of his valet and lamented, "It's not the prime minister in the dream, it's you in the dream!" " When Cao Cao heard this, he hated Yang Xiu even more. Cao Zhi, the third son of Cao Cao, worships Yang Xiu's talent very much, and often invites Yang Xiu to talk about the history of literary theory, which never stops. Cao Cao discussed it with everyone and wanted to make A Zhi a prince. After xelloss knew this, he secretly invited Wu Zhi, the main official of Chao Ge, to his house to discuss this matter. Because he was afraid that someone would notice, he hid Wu Zhi in a big bamboo basket and only said it was a silk horse and took it to his home. When Yang Xiu found out, he immediately told Cao Cao. Cao Cao sent people to xelloss's house to observe secretly. Xelloss told Wu quality in panic. Wu Zhi said, "Don't worry. Tomorrow, we will put silk on bamboo slips and take it home to confuse them. " Cao Pi took some silks into the house with bamboo slips according to Wu's words. Cao Cao's emissary searched the bamboo slips and found that they were silk, so he returned to Cao Cao, who suspected that Yang Xiu had hurt Xelloss and hated Yang Xiu even more. Cao Cao wanted to try the talents of Cao Pi and Cao Zhi. One day, they were ordered to go out of the gate of Yecheng, but privately, the officials guarding the gate were told not to let them go out. Xelloss went to the gate first, and was stopped by the gatekeeper. Xelloss had to return. When Cao Zhi heard this, he asked Yang Xiu what to do. Yang Xiu said, "The king ordered you to leave the city gate. If there is any obstacle, cut him off. " Cao Zhi listened to his words and arrived at the gate. The doorman stopped him. Cao Zhi shouted at him: "I went out on orders from the King to see who dared to stop him and immediately beheaded the officer who stopped him!" So Cao Cao thinks Cao Zhi is very capable. Later, someone told Cao Cao, "Yang Xiu taught Cao Zhi to do this." Cao Cao was furious, so he no longer liked Cao Zhi. Yang Xiu once taught Cao Zhi more than ten answers. As long as Cao Cao asks questions, Cao Zhi answers them one by one. Cao Cao only needs to ask Cao Zhi about military affairs, and Cao Zhi answers like a stream. Cao Cao is particularly suspicious. Later, Cao Pi secretly bribed people around Cao Zhi and stole an answer to tell Cao Cao. Cao Cao was furious and said, "How dare this boy cheat me like this!" Then came the idea of killing Yang Xiu, and now I killed him on charges of disturbing people's hearts.
