details of life
Cao Jiazi, who took refuge in Cao Cao, was one of Cao Cao's main counselors. Guo Jia was born in poverty and had great ambitions since childhood. Since the age of 20, I have made secret friends with people of insight ("from weak crown to unknown trace, close friends make English friends"), and I have no contact with secular people ("I don't contact people with customs, so many people don't know, but the people who know are amazing." )。 These "Ying Juan" should include Yu Xun, Xin Ping, Guo Tu and others to talk about the current situation. This laid the foundation for his career as a counselor. At first he went to Yuan Shao, a very powerful man, and Yuan Shao was very respectful to him. But Guo Jia found that Yuan Shao was indecisive and not good at employing people, so it was difficult to achieve great things. He said to Xin Ping and Guo Tu, the advisers under Yuan Shao's account, "The wise judge the monarch, so they can do anything and achieve fame." . Yuan Gong wanted to be the corporal of the Duke of Zhou, but he didn't know the opportunity to choose someone. If you want to help the world together, it is difficult to decide the business of the overlord! "("The reflection of Shu Wei Cheng Guo Dong Liu Jiang Liu Chuan ") also said:" I will fight for the Lord even more, and my son will die! "However, the two said," The Yuan family is kind to the world, and many people return it. Now it is the most powerful. What shall we do? "(History as a Mirror, Volume 62) Guo Jiazhi and his wife did not find Yuan Shao's shortcomings, so they did not say much and resolutely left. In this way, Guo Jia idle for six years. In the first year of Jian 'an (196), Cao Cao was a highly respected counselor and dramatist, and Cao Cao valued him very much. However, his ambition died, so Cao Cao wrote a letter to his counselor Yu Xun. The book says, "When ambition dies, you can't talk to the planner. Who can replace you and Gu Duo? " (The Reflection of the Three Kingdoms Shu Wei Cheng Guo Dong Liu Jiang Liu Chuan) After reading the letter, Yu Xun recommended Guo Jia to Cao Cao. Cao Cao took Guo Jia to his own camp. The two talked for a long time, and Cao Cao praised him: "If you want to achieve great things, you must have this person." (The Story of the Three Kingdoms, Shu Wei and Guo Jiachuan) Guo Jia was deeply impressed by Cao Cao's tolerance and said happily, "Your Excellency is really." ("The Reflection of the Three Kingdoms, Shu Wei, Cheng, Liu Jiang, Liu Chuan") Cao Cao appointed Guo Jia as the air force's drink offering. Guo Jia in the animated version of Cao Cao's Romance of the Three Kingdoms. At that time, the princes were divided into a corner and had no ambition to swallow the four seas. In this case, Guo Jia's accurate judgment of the opponent's psychological state often becomes the key to Cao Cao's victory. In the first year of Jian 'an (196), Lu Bu shot a halberd at Yuanmen to save Liu Bei, and Liu Bei soon gained more than 10,000 soldiers, which caused Lu Bu's jealousy and led troops to attack Liu Bei. Liu Bei took refuge in Cao Cao, and Cao Cao treated him very well. It can be seen that Liu Bei led Yuzhou animal husbandry. Suggest that Cao Cao kill Liu Bei to prevent future trouble. Cao Cao asked Guo Jia for advice, and Guo Jia analyzed and said, "Yes. And the people arise, in order to eliminate violence for the people, push the honest soldiers to recruit Jie Jun, but they are still afraid of not believing it. Today, there are heroes, and they also harm poverty in the name of harming morality. In this way, the wise will doubt themselves, change their minds, choose their own masters, and who will decide the world! In addition to the suffering of one person, I hope to be at home all over the world, and safe opportunities are also indispensable. " Cao Cao smiled and said, "You guessed it right." ("Guo Guchuan, the Three Kingdoms") So Pei Songzhi sent more troops to Liu Bei and sent him to Peixian County (now Peixian County, Jiangsu Province) to collect skirmishers against Lu Bu. On Ten Wins In the second year of Jian 'an (197), Yuan Shao and Cao Cao co-wrote a book, which was arrogant and slow. Cao Cao was furious. To Xun and Guo Jia, he said, "How about not getting justice today?" The two replied: "Liu and Xiang are not equal, as everyone knows." Han Zu just outsmarted Xiang Yu, so although Yu was strong, he was finally captured. Shao lost ten times today, and Gong won ten times. Although Shao is strong, there is nothing he can do. Salt is complicated, the public body makes nature, and this way wins; Salt to counter-action, public to serve the world, this righteousness wins; Since Huan and Mausoleum, the imperial court has been disgraced, and the salt is wide and not taken. The public will know how to correct it and win. The outside is wide and the inside is taboo, and people are suspicious. If you are only a relative's child, it is easy to be simple and clear. There is no doubt that the selection of people is based on merit, regardless of distance, and this degree will win. Shao seeks more and less, and loses in the aftermath. The public must do something, and the strain is endless. This is to win; It is a great honor to talk about how to accept fame. Scholars' good words are mostly in return, and the public and even their hearts treat others, not for empty beauty. Scholars are willing to use their loyalty and foresight. This Desheng also sees people's hunger and cold, sympathizes with them and treats them with color. What they don't see, what they don't consider, or what they don't have is open to the current small things, and sometimes they are careless. As for major events, it is a clear victory to increase the power of the minister Shao, and the rumors are chaotic. Under the public rule, the infiltration is not good; Salt is unknowable, CCBA is polite, not just right, this article won; Shao Hao is an air diver, and I don't know what the soldiers want. The crowd is smaller than the crowd, and the soldiers are like gods. Soldiers rely on it, and enemies are afraid. The same is true in Vu Thang. "Cao Caoxiao said," as qing said, why should I be lonely? Guo Jia added, "A few troops attacked Gongsun Zan from the north, and because of an expedition, they took Lu Bu to the east. If Shao is the enemy and cloth is the aid, it will be deeply harmful. " Yu Xun said: "If we don't win Lu Bu first, Hebei won't be in Yi Tu." Cao Cao said, "Of course. I'm confused, and I'm afraid Shao will invade Guanzhong, confuse Qiang Hu in the west and lure Shu Han in the south. It's that I'm alone and I'm against five-sixths of the world. What should I do? " Yu Xun said, "There are more than ten generals in Guanzhong, but Han Sui and Marten are the strongest. When he saw the dispute in Shandong, he must support the masses to protect themselves. Now, if he bites the hand that feeds him and sends a special envoy to make peace, although he can't live in peace for a long time, he will be more motionless than the public security in Shandong. The servant in the middle school and the servant in the book shot Zhong You with wisdom. If it belongs to the west, the public will have no worries. "The above is the famous theory of ten wins, which laid the ideological foundation for Cao Cao to defeat Yuan Shao and pacify the Central Plains, thus relieving Cao Cao's worries about defeating Yuan Shao and inspiring Cao Cao's determination to unify the world. Cao Cao appointed Zhong You as a corps commander, in charge of all the armies in Guanzhong. From Zhong You to Chang 'an, he sent a letter to Han Sui and Marten. Both of them sent their sons to Beijing as hostages. After killing Lu Bu for three years (198), Cao Cao conquered Lu Bu. Lyu3 bu4 retreats and sticks to Xiapi (now northwest of Suining, Jiangsu). Cao Jun was unable to attack for a long time, and the soldiers were very tired. Cao Cao wants to retreat. Xun You and Guo Jia, however, saw the chance to win, and pointed out: "Lu Bu is brave and courageous, and now he has lost all three wars, and his spirit is failing. The three armed forces are dominated by generals, and the surrender of the army has made the army uninterested. Husband Chen Gong, wise and late. Today, the cloth has not been restored, and the palace has not yet decided. If you attack it urgently, you can pull it out. " (Biography of the Three Kingdoms of Shu Wei and Xun You) Cao Cao nodded in agreement, so Cao Jun led the two armies of Yishui and Surabaya to fill the city. After more than a month, Lu Bu was even more sleepy. In December, Lu Bu rebelled against Hou Cheng, Song Xian and Xu Wei. , and Cao Jun captured pi. Lu Bu was surrounded by the White Gate Tower and was forced to surrender. Cao Cao ordered the killing of Lu Bu, Chen Gong and Seibel. And passed the first capital, moving troops in victory. In this campaign, Cao Cao annihilated his sworn enemy Lu Bu, creating favorable conditions for eliminating Yuan Shao and other separatist forces and completing the great cause of reunifying the north. Assisted Cao Cao to establish Jian 'an for four years (199), and Cao Cao welcomed the Han Emperor and moved his capital to Xu County (now Henan). After that, he took charge of military and political power and state affairs, and the emperor became a puppet. Dong Cheng, a general riding a chariot, accepted the imperial edict and plotted with Liu Bei, a captain of Changshui, General Wu and Prince Fuming to get rid of Cao Cao. Liu Bei was afraid of Cao Cao's suspicion and wanted to get rid of Cao Cao's control. He took advantage of the rout of the right general Yuan Shu, volunteered and went to intercept with the general Zhu Ling. After hearing this, Guo Jia, Cheng Yu and Dong Zhao all said, "It is impossible to send it away." ("The Reflection of the Three Kingdoms, Shu Wei, Cheng, Liu Jiang, Liu Chuan") Cao Cao regretted it, and it was not enough to send someone to chase it at once. After Yuan Shunan fled Shouchun (now Shouxian County, Anhui Province), Zhu Ling moved back to North Korea. In December, when Liu Bei was sent by Cao Cao to crusade against Yuan Shao, he attacked and beheaded Xuzhou secretariat (under Pi, now northwest of Suining, Jiangsu) and defeated Sima Changliu sent by Cao Cao. It is reported that Xuzhou and Xiapi (now northwest of Suining, Jiangsu) betrayed Cao Cao and responded to Yuan Shao. In the fifth year of Jian 'an (200 years), Cao Cao's army and Yuan Shao were at loggerheads in Guandu. Wheeled general Dong Cheng's plan to assassinate Cao Cao leaked, and Dong Cheng, Wang Zifu and Ji Ze were all slaughtered, while Liu Bei, who participated in the conspiracy, was at large and became more and more powerful. Cao Cao wanted to conquer Liu Bei himself, but his ministers were worried that Yuan Shao would attack from behind. They all said, "Yuan Shao is also a man who competes with the public for the world. Now, Shao Fang has come and abandoned the East. What will happen when Shao takes advantage of others? " Cao Cao said, "Liu Bei is an outstanding man. If you don't strike today, it will be a disaster. " Guo Jia also thinks: "Suspicion, uninvited guests. Prepare for a new beginning, everything is unconcerned, and if you strike hard, you will lose (Zi Jian Juan Sixty-three). However, the "Three Kingdoms" said that Cao Cao intended to cut off future troubles for Cao Cao, so he led an army to crusade against Liu Bei. Jizhou did not drive Tian Feng to persuade Yuan Shao to attack Cao Cao's rear, but Yuan Shao refused to send troops on the grounds that his young son was seriously ill. When Liu Bei learned that Cao Cao was coming, he was frightened and rode out of the city with dozens of heads. Sure enough, he saw Cao Jun's standards and had to rush into battle. He was defeated by Cao Jun and Liu Bei's wife was captured. Then Cao Cao captured Pi, forced Liu Bei to surrender Guan Yu, and attacked Chang Xi, who was attached to Liu Bei, to break Pi. Liu Bei fled to Yecheng (now southwest of Linzhang, Hebei Province) to go to Yuan Shao, and gradually collected scattered defeated troops, which became the force for Yuan Shao to attack Cao on a large scale. In this battle, Cao Cao quickly defeated Liu Bei, avoiding the situation of fighting on both sides in the battle of Guandu. From the second year of Xingping (195), Sun Ce used Yuan Shu's soldiers to cross the river to conquer Jiangdong (see Sun Ce's Battle of Pingjiang East). By the fifth year of Jian 'an (200), Sun Ce had done his best to become a strongman of independent regime. At this time, Sun Ce heard that Cao Cao and Yuan Shao were at loggerheads in Guandu, and wanted to lead the army to cross the river and attack Xuchang in the north. Cao Jun was surprised. Cao Cao, who was already at a disadvantage in the stalemate with Yuan Shao, could no longer afford to defend Xu Du. Once Xu Du falls, Cao Cao's camp will immediately fall apart. This is the most turbulent period of Cao Cao's camp, and many people began to secretly flatter Yuan Shao, ready to leave a way out for themselves. At this critical moment, Guo Jia unexpectedly put forward an incredible view: there is no need to take out troops to defend Xudu, because Sun Ce can't come. Guo Jia said, "If you plan to merge with Jiangdong, you will be punished by heroes, and those who can gain human strength will also be punished by them. However, the strategy is light and unprepared. Although there are millions of people, it is tantamount to walking alone in the Central Plains. If an assassin lies down, a person is an enemy's ear. In my opinion, you will die at the hands of ordinary people (reflection of Shu Wei Cheng Guo Dong Liu Jiang Liu Chuan). Before the battle of Guandu, Sun Ce's vanguard troops were defeated by Chen Deng, the prefect of Guangling. Soon, Sun Ce was hit by Guo and later killed by an assassin. In the same year, Guo Jia defeated Yuan Shao with Cao Cao in the battle of Guandu with little success. In May of the seventh year of Jian 'an (20 1), Yuan Shao died of vomiting blood due to defeat. His youngest son Yuan Shangji, a general and Jizhou, led his eldest son Yuan Tan to lead a few troops to defend Liyang. In September, Cao Jun crossed the Yellow River to attack Liyang, and Yuan Tan asked for more troops. Yuan Shang was afraid that Yuan Tan would seize his power when he had more soldiers, so he led his army to help him and fought Cao Jun in Liyang. In February of the eighth year of Jian 'an (2003), Cao Jun launched a general attack and arrived at the gates of Liyang. Yuan Jun was defeated, Yuan Shang and Yuan Tan abandoned the city and fled, and Cao Jun occupied Liyang. In April, Cao Cao marched into Yecheng, in order to enrich rations and rob wheat. Yuan Jun took the opportunity to launch a counterattack, and Cao Jun suffered a slight setback. Cao Cao intends to reorganize the siege. Guo Jia thought: "Yuan Shao loves this second son, so he should not stand up. With Guo Tu and Ji Feng as counselors, the two contended for each other and refused to give way to each other. If you are in a hurry, you will be deadlocked, and then you will win your heart. It is better to go south to Jingzhou, and if you sign Liu Biao, wait for it to change; Turn it into a blow, and decide it at one stroke "("The Reflection of the Three Kingdoms Shu Wei Cheng Guo Dong Liu Jiang Liu Chuan "). Cao Cao accepted his plan. In May, withdrawing troops returned to Xudu (now Xu Changdong, Henan). The fact that Jia Xin was stationed in Liyang to monitor Yuan Jun ... In the ninth year of Jian 'an (203), Yuan Shang and Yuan Tan really started fighting. Yuan Tan was defeated by Yuan Shang and sent Xin Pi to beg Cao Cao for surrender. Cao Caosui attacked Yecheng (now southwest of Linzhang, Hebei Province) in the name of supporting Yuan Tan. In July, Yuan fled to Zhongshan (now Dingzhou, Hebei Province), and the trench was captured ... The defenders of Yecheng heard that the flood had collapsed. In October, Yuan Shang's power was basically wiped out by Cao Cao. When Cao Cao besieged Yecheng, Yuan Tan, who had already defected to Cao Cao, betrayed Cao Cao, seized Ganling, Anping, Bohai, Hejian and other places, and attacked Yuan Shang who fled to Zhongshan (now Dingzhou, Hebei Province), forcing Yuan Shang to flee again (now Dong Gu 'an, Yixian County, Hebei Province) and take refuge in Yuan Xi in Youzhou (now southwest of Beijing City). Yuan Tan collected the remnants of Yuan Shang and stationed in Longchou (now southeast of Shandong Plain). After defeating Yuan Shang, Cao Cao, based on the principle of divide and rule, used Yuan Tan's betrayal of the alliance as an excuse to send troops to attack Yuan Tan. In the first month of the tenth year of Jian 'an (204), Cao Cao attacked Nanpi, defeated Yuan Jun, occupied Nanpi, and Yuan Tan fled, and was killed by Cao Jun. Yuan Tan's counties all surrendered to Cao Cao. Guo Jia said to Cao Cao: "We should pay more attention to youth, seclusion and celebrities, so that people will pay attention to it." (History as a Mirror, Volume 64). In order to appease the local government, Cao Cao adopted Guo Jia's suggestion and stabilized the rule. Jizhou was pacified, and Guo Jia was named Zhiyang Hou Ting for his work. Guo Jia's death, a beautiful Guo Jia beauty ~ Wuhuan tribe, a minority in western Liaoning, took advantage of the war in the Central Plains to exile more than 6,543,800 Han border people. After Cao Cao took Jizhou and killed Yuan Tan, Yuan and Yuan Shang fled to Wuhuan. Together, they invaded the border constantly. In order to unify the north, Cao Cao began an expedition to Wuhuan in the autumn of the twelfth year of Jian 'an (2007). When Liu Bei heard the news, he immediately rushed to Jingzhou to persuade Liu Biao to seize Xudu (now Xu Changdong, Henan Province) while Cao Cao was making a northern expedition to Wuhuan, and welcome Xian Di to Xinghan. Cao Cao was very worried, and all the generals said, "Yuan Shang is deaf, greedy and has no relatives. How can he use it?"! Today's in-depth levy, Liu Bei will say that Liu Biao will attack Xu, and when things change, things cannot be regretted "(Zi Jian, Volume 65). Guo Jia, however, made a detailed analysis of the feasibility and great significance of the Pingwu Huan War: "Although the public is a big country, relying on its distance, it will not need equipment. Because it is defenseless, it can be shattered with a sudden blow. Yuan Shao was kind to the people, while the Shang brothers survived. Today, the people of the four States are attached to each other by force, but they give up virtue and go south instead. Because of the capital of 50 thousand, they have recruited the minister of the dead master. When the conference semifinals move, the people dare not respond, so as to give birth to the heart of the tower shield and become a coveted plan. They are afraid of being green and not having their own. Table, sit and talk, self-knowledge is not enough to prevent, heavy responsibility may not be made, light responsibility may not be used. Although the expedition to the virtual country is empty, the public has no worries "(The History of the Three Kingdoms Shu Wei Guo Cheng Dong Liu Liu Jiangchuan). Hearing this, Cao Cao was at a loss and immediately sent his troops north. When he arrived in Iraq (now northwest of Xiongxian County, Hebei Province), Guo Jia offered a plan and said, "Soldiers are very expensive. Attacking people thousands of miles away, there are many treasures, which are difficult to be interesting. You should be prepared when you hear it. It is better to leave the trench, lead the way lightly, and cover up its surprise attack "(reflection Shu Wei Cheng Liu Jiang Liu Chuan). However, in autumn and July, when the sea road was blocked, Tian Chou invited a guide to take Cao Jun out of Lulongsai, but the road beyond the Great Wall was blocked, so he cut a mountain to fill the valley, passed through Baitan, Pinggang and Xianbeiting for more than 500 miles, and entered Liucheng. In less than two hundred miles, the enemy found that Yuan Shang, Tatun, Khan Louban in western Liaoning and Khan Nengchen in Beiping arrived and led tens of thousands of cavalry to meet. In August, in Bailangshan (now Bailushan in the east of Harqin Left-wing Mongolian Autonomous County in Liaoning Province), the two armies met unexpectedly, and the Lu army was outnumbered. In addition, Cao Jun didn't bring the trench and few armored personnel, so he was afraid of both sides. Zuo Zongtang climbed to the top of the mountain and took a look. Seeing that Lu Jun was "incomplete", he seized the opportunity, and the soldiers would block him. It was a battle to annihilate the main force of Wuhuan and the remnants of the Yuan Dynasty, behead the tower shield and the generals 10, and capture more than 200,000 people (see the Battle of White Wolf Mountain). Liaodong Khan was a slave of Sufu Pill, Liaoxi and Peiping, and abandoned his own kind to compete with Shang and Ben. Yuan Shang and Yuan went to see Gongsun Kang, the satrap of Liaodong County. Cao Cao didn't pursue, just sat and watched the situation, claiming that he was waiting for Gongsun Kang to send Er Yuan's head. In September, Cao Cao withdrew from Liucheng. Soon, Gongsun Kang killed Yuan Shang, Yuan and Liaodong Khan Supu Pill. According to Guo Jia's plan, Cao Cao pacified Wuwan and unified the whole area north of the Yellow River Basin. Guo Jia's "Deep understanding of reason and strategy, reaching for things". Cao Cao said, "Only filial piety can make you understand loneliness" (The Three Kingdoms Shu Wei Cheng Liu Jiang Liu Chuan). On the way to the Northern Expedition, Guo Jia was seriously ill in bed, and Cao Cao kept sending people to visit him. "Ask the sick to stagger." Guo Jia died at the age of 38 shortly after returning to Li. Cao Cao was heartbroken and said to Xun You and others, "You gentlemen are orphans, and only filial piety is the least. What's going on in the world, if you want to return to its future, you will die in middle age, and your life will be the same "("Reflection on Guo Jiachuan "). This is a statement to the world: "The army has been offering wine to Guo Jia for ten years. Every time there is a big discussion, the enemy will change. I haven't decided my policy yet. I need to make it work. Pacify the world and strive for high achievements. Unfortunately, life is short and my career is not over. It is really unforgettable to think of Jia Xun. There are 800 households in Zengcheng, and 1,000 households in the top "(The History of the Three Kingdoms Shu Wei Cheng Liu Jiang Liu Chuan). Therefore, Guo Jia was named Hou Zhen and his son Guo Yisi. After the defeat of Battle of Red Cliffs, Cao Cao sighed, "Guo Fengxiao is here, so I am not alone" ("The Reflection of the Three Kingdoms Shu Wei Cheng Liu Jiang Liu Chuan"). At first, Chen Qun blamed Guo Jia for failing the inspection and repeatedly accused Guo Jia in the DPRK, but Guo Jia kept a cool smile. Cao Cao is more of a reuse of Guo Jia, and Chen Qun can keep in, Cao Cao is also very happy. As a counselor, Guo Jia made great contributions to Cao Cao's unification of the North. According to historical records, he, Cheng Yu, Dong Zhao and Jiang Ji are also called "wizards of the world" (The History of the Three Kingdoms,,, Jiang, Liu Chuan). It's a pity that Guo Jia died young, with unfulfilled ambition.
Personality assessment
First, choose the Lord and do things. Guo Jia was ambitious since he was a child. At the age of twenty, he was keenly aware that there would be chaos in the world, so he lived in seclusion and waited for the opportunity. On the other hand, he keeps in touch with talented people in secret. Guo Jia's initial seclusion was due to Tian Feng's attachment to the most powerful Yuan Shao at that time. Yuan Shao had great respect for Guo Jia and others and treated them with courtesy. But after a few days, Guo Jia saw that Yuan Shao was indecisive and not good at employing people, and only one person resolutely left. Just as Cao Cao was recruiting talents, Yu Xun and Cheng Yu joined hands to present Guo Jia! Cao Cao summoned Guo Jia and asked Yuan Shao. Guo Jia famously said, "Ten wins and ten losses", when Yuan Shao attacked Gongsun Zan, he offered a plan to conquer Lu Bu in one fell swoop. This will expand his own strength and avoid the threat of Lu Bu from the side in the decisive battle between Yuan and Cao. After hearing this, Cao Cao sighed: "It must be this person who makes orphans become great things." Guo Jia was impressed by Cao Cao's talent and ambition. When he left Cao Cao's camp, he was overjoyed and said; "It's true, my Lord." From then on, Guo Jia used Cao Cao's strategist, the strategist, to offer a drink offering. Make suggestions for Cao Cao's four-party campaign and serve him faithfully. Second, the plan was broken by Liu Lu. In February, Cao Cao adopted Guo Jia's plan to send troops to Lu Bu. Cao Jun defeated Cheng Peng first, then Lu Bu, and finally the army besieged Pi. However, Lu Bu persisted and couldn't get out. Cao Cao couldn't attack for a long time, so he thought of withdrawing troops. Guo Jia persuaded Cao Cao to continue to attack the city. "Although Lyu3 bu4 brave, now all three wars are lost, the spirit has declined. The generals of the three armed forces will decline. Chen Gong is resourceful, but slow to respond. Now is the time to use the spirit of Lu Bu and Chen Gong's plan to March into the emergency attack, and we will certainly defeat Lu Bu. " Cao Cao acted according to the plan, while attacking the city, he drowned Pi with Yi and Si Shui. In December of the same year, Pi was conquered, and Lu Bu and Chen Gong were captured and killed alive. In the fourth year of Jian 'an, Cao Cao sent Liu Bei to attack the invading Yuan Shu. Guo Jia was shocked and stopped: "Don't let Liu Bei lead the army out, or it will be reversed." Cao Cao regretted it. Liu Bei immediately killed Che Zhou, the secretariat of Xuzhou, and United against Cao. Cao Jun was attacked from both sides. Cao Cao wanted to quickly send his troops to destroy Liu and turn to Yuan. People are afraid that Yuan Shao will attack from behind. Cao Cao was indecisive, and Guo Jia analyzed: "Yuan Shao has always been indecisive and unresponsive. Liu Beigang rebelled not long ago, and the people did not return, and his foothold was unstable. He attacks quickly, and he is doomed to lose. Then return to Li to deal with Yuan Shao. This is the best time to change between Scylla and Charybdis on the eve of the decisive battle, and we must not lose it. " Cao Cao finally strengthened his confidence and returned from Guandu to attack Liu. He broke the "wife-taking" in World War I, captured his general Guan Yu alive and won the next Pi. As Guo Jia expected, Yuan Shao didn't respond, and Liu Bei was defeated. Third, win from two yuan. After the battle of Guandu, Lien Chan, the second son, won. All the generals advocate sweeping Eryuan thoroughly. Guo Jia, on the other hand, added fuel to the flames in the crowd and found a new way. This paper analyzes the contradiction of yuan brothers's views on Cao Cao. If we attack them, we will work together. If we slow them down, we will be coaxed. It is suggested that Cao Cao return to the military uniform and levy Liu Biao in the south, "waiting for it to change." Sure enough, the second yuan competed for territory. Cao Cao took the opportunity to return to the north to attack one by one. Er Yuan died and fled. Thanks to Guo Jia's clever plan, the battle was won easily, smoothly and thoroughly. At this time, Yuan Shang fled to Wu Heng, and the generals of Jun thought it was not worthwhile to attack Wu Heng for Yuan Shang, making Xuchang empty and attacking Liu Bei. In the unanimous opposition, Guo Jia once again incisively and incisively analyzed the feasibility and significance of the Pingwuheng campaign. Guo Jia first said that the expropriation of Wu Heng is of great significance for consolidating the area north of the Yellow River just captured by Cao Jun .. It also revealed the contradiction between Liu Biao and Liu Bei, and pointed out that Liu Biao would never let Liu Bei sneak up on Xudu. Cao Cao listened to his words and quickly led the army to war. Guo Jia also advised the army to be quick and expensive, travel light and take it by surprise. Sure enough, Cao Jun approached Liucheng, where Wu Hengjun lived, for more than one hundred miles before being discovered. As a result, Zhang Liao suddenly attacked and killed Wu Hengjun in World War I ... Yuan Shang fled into Liaodong again, and Gongsun Kang, the prefect of Liaodong, offered his head. According to Guo Jia's plan, Cao Cao finally completely pacified the north and unified the whole Yellow River basin! Fourth, the monarch and the minister know each other. Almost every time Cao Cao went to war, Guo Jia followed the military plane of the General Staff. When marching, Cao Cao walked side by side, and he also sat with Cao Cao at the meeting. Guo Jia's strategy is always correct when discussing military affairs, and his strategy has never been miscalculated, which really achieves the purpose of calculating everything. Guo Jia didn't keep etiquette, but he was reused by Cao Cao because of his extraordinary ingenuity. Only Cao Cao dared to use someone who despised etiquette like Guo Jia. Guo Jia, who is in her twenties, was cited as a "bosom friend". But also placed infinite hopes on the young Guo Jia, intending to entrust the affairs of governing the country behind him to Guo Jia after pacifying the world. When Guo Jia was seriously ill in bed, Cao Cao kept sending people to visit him. "The people who ask questions are staggered." Guo Jia died of illness, and Cao Cao went to the mourning hall with great grief. More poetic and concise language expressed his infinite sadness and regret: "Alas, filial piety! Filial piety hurts! Cherish filial piety! " (Biography of Fu Zi) Later, he said to the court: "It has been ten years since the army offered wine to Guo Jia. Every time there is a big discussion, the enemy will change. I haven't decided my policy yet. I need to make it work. Pacify the world and strive for high achievements. Unfortunately, life is short and my career is not over. It is really unforgettable to think of Jia Xun. You can increase 800 households and 1000 households. " To sum up, Guo Jia is Cao Cao's favorite and most effective counselor with profound knowledge and qualifications. It should be said that the reason why Cao Cao fought like a god was "like Sun Wu". Among them, Guo Jia played a very important role because of his strategizing. In the words of Cao Cao. It is: "pacify the world and aim high!"
