The basic quality of a strategist lies in his clear mind, strong insight, profound thinking and foresight. Strategists' levels, levels and realms are also divided accordingly. Cheng Yu sees things quickly and is unpredictable, which shows everyone's unparalleled talent.
Later, Cao Cao welcomed Xu Chang, the capital of Emperor Wu of Han Dynasty, and made history with Cheng Yu. At that time, Yanzhou was not completely stable and obedient, so Cao Cao used Cheng Yu as the governor of the East, and led Yin Ji County to be in charge of all affairs in Yanzhou. After Liu Bei lost Xuzhou, he came to submit to Cao Cao. Cheng Yu persuaded Cao Cao to kill Liu Bei quickly, but Cao Cao wouldn't listen. Later, Cao Cao sent Liu Bei to Xuzhou to intercept Yuan Shu. Hearing this, Cheng Yu and Guo stopped Cao Cao together and said, "Cao Gong, you didn't kill Liu Bei last time. Cheng Yu and others really can't compare with your super-knowledge. Now you lend him a soldier to go out to fight, he must be disloyal. " Cao Cao regretted hearing this and sent someone to chase Liu Bei back, but he couldn't catch up. Due to Yuan Shu's death, when Liu Bei arrived in Xuzhou, he killed Che Zhou, Cao Cao's spy, and transferred troops to betray Cao Cao.
Cao Cao conquered Jingzhou and Liu Bei defected to Sun Wu. Many commentators believe that Sun Quan will definitely kill Liu Bei. Cheng Yu believes: "Sun Quan has just acceded to the throne, but he has not been respected and feared by heroes at home. Cao Gong is invincible in the world. He just conquered Jingzhou, and his military strength shocked the whole country. Although sun quan has a little strategy, he knows that he can't fight tso alone. Liu Bei is known as a hero, and Guan Yu and Zhang Fei are both' ten thousand enemies'. Sun Quan will definitely subsidize some of Liu Bei's troops to defend our army, which is forced by the situation and difficult to break. With the support of Sun Quan, Liu Bei's power has been formed, and Sun Quan can't have another chance to kill Liu Bei. " Sun Quan gave Liu Bei a group of soldiers and used him to resist Cao Cao.
Cheng Yu's knowledge had a great influence on his descendants, and Cheng Xiao, the grandson of Cheng Yu, also had a unique accomplishment in this respect. Cheng Xiao served as assistant minister of Huangmen during Jiaping period (AD 249-254). At that time, the school officials created by Cao Cao in his early years were rampant. Therefore, Cheng Xiao said: "Zhou Li said:' Setting up a lawsuit and sharing responsibility is the norm of all peoples.' Chunqiu Zhuan also said:' There are ten suns in the world and ten people underground.' Fools cannot rule wise men, and untouchables cannot rule nobles. Since then, they have jointly established the authority of sages and established their lofty fashion and reputation. Officials are clearly assessed according to their respective achievements, and performance appraisal is concentrated once every nine years. Let them practice their careers separately, and they can't leave their posts. Therefore, Luan Shu, the ruling minister of the state of Jin, wanted to save the Kim family, but his son did not listen. The dead man was lying on the road, and Prime Minister Bingji thought such a thing was not within his scope of duties, so he abandoned it. The superiors don't have to blame their subordinates for their achievements within their duties, and subordinates don't want rewards outside their duties. Officials and assistants have no sovereignty, and the people do not work in two industries. This is the essence of governing the country, which determines the chaos in the world. Look at the official history of the three generations from a distance, and look at the political traces of Qin and Han dynasties. Although the official names of past dynasties have been changed and changed, the positions of officials are not the same. As for respecting the monarch and restraining the generals, it is exactly the same to distinguish between posts and laws. At the beginning, no school officials easily intervened and participated in ordinary affairs and government affairs. This is the time when Taizu Wu just started his great cause. Because officials still have petty crimes and have to be picketed, they have temporarily placed the post of school affairs. However, at that time, they had a good inspection and audit, and they were not as indulgent as they are today. This is an expedient measure in the hegemonic era, not a serious imperial code. Since then, school officials have gradually gained attention and trust, becoming a disease and a disadvantage that no one can clean up. In this way, school officials can picket the palace and the court, and they can manage the officials of various departments. Officials have no fixed official duties and no division of labor and authority. You can dispose of everything at will, as long as selfishness feels appropriate. Laws can be made at will under his pen without following imperial edicts; The prison can be located in front of his house, and there is no need to take care of handling cases and interrogation. The election of officials belongs to officials, and officials often mistake caution for carelessness; Think of confused people as talented people. In management affairs, we often regard harshness and tyranny as fairness and strictness, and regard conformity as cowardice and weakness. Externally, relying on the prestige of the army to create momentum; Internally, a group of treacherous court officials gathered into a confidant. Ministers are ashamed to compete with them for power and profit, and they are forbearing; The villain is afraid of his sharpness, depressed with grief and indignation, but there is nowhere to cry. As a result, adulterers like Yin Mo openly conspired before his eyes. Their sins are obvious, and everyone who walks by knows them; But those slender sins have not been heard by the world for many years. This is neither Zhou Li's original intention of appointing officials nor the ancient meaning of "There are ten categories of people" in Spring and Autumn Annals. Now there are officials outside, in charge of officials, Cao Shu; There is an assistant minister who is in charge of the military and can be transferred to a captain to supervise the emperor of the capital; Cheng in the empire, managing the imperial palace. These officials are filled by talents selected by high standards; They all use clear scientific and technological edicts in advance to supervise their possible mistakes. If the above sages can do their best, it's no good just being guarded by a school official. If you choose a good scholar as a school official, it is actually a layer of officials besides Cheng and Si Su in the suggestion. If we still choose as we did in the old days, traitors like Yin Mo will be born again now. I go in and I go out, and after repeated calculations, I think this office is really useless. In the past, Sang Hongyang claimed to benefit the Han Dynasty, but Bo Shi thought that it would only rain if Sang Hongyang was cooked and killed. If political gains and losses are bound to touch the world, I am afraid that floods and droughts may not be caused by the improper behavior of school officials. Cao Gonggong is far away from the gentleman and close to the villain, so the national style of The Book of Songs implies irony. Abandoned the minister, but colluded with the little minister and decided that Jiang said he was guilty. Even if the school officials benefit the country, they still hurt the hearts of ministers from the perspective of courtesy and righteousness. What's more, the treacherous nature of school officials has been exposed. If you don't recall the school official at this time, what you see is not compensation, but praise, stubbornness and never looking back. "So wei recalled the field officer.
Cheng Yu's foresight also helped him stand firm in the political storm without any impact. After the Central Plains was pacified, Cheng Yu took the old adage of knowing that he had never humiliated others as a precept, made great achievements, returned the relieving of the military power, declined the number of guests, and settled down at home.
Cheng Yu is a great hero of Cao Shi Group. In Cao Cao's own words, "the defeat of Yanzhou, without Cheng Yu's plan, will never unify the Central Plains and dominate the North."
Cheng Yu has a strong and violent personality, and many people are offended. Someone once accused Cheng Yu of rebellion, but Cao Cao listened, and the reward and preferential treatment for Cheng Yu were even more generous. After the establishment of Wei, he was appointed as a lieutenant. He was removed from office because he competed with assistant Xing Zhen for the dignity of his attendants. After Wei Wendi Cao Pi ascended the throne, Cheng Yu was re-used as Wei State, and he was appointed as Anxiang Hou, adding 300 food cities and merging 800 original food cities. His youngest son, Cheng Yan, and his grandson, Cheng Xiao, were appointed as liehou. When he was about to go public, it coincided with his death. Wei Wendi also wept bitterly for his death, posthumously awarded him the title of riding general, and gave him posthumous title Suhou. The title was inherited by his son Chengwu. After Chengwu's death, the title was inherited by his son Ke Cheng. After Ke Cheng's death, the title was inherited by his son Cheng Liang.
