Guo Jia's appearance took up only one sixth of the space from the tenth chapter of "The King of Qin Ma Teng Juyi reported his father and Cao Cao's selection of teachers" to the end of the thirty-third chapter of "Cao Pi took advantage of the situation to mobilize his teachers and Guo Jiading Liaodong". Thirty-eight years of life and eleven years of work experience are too short. Guo Jia, on the other hand, is listed as one of Cao Cao's five advisers, and even as the first of them by many people. Other advisers appeared and everyone nodded respectfully. When Guo Jia appeared, everyone stood up and cheered. Guo Jia, we love you. We are all your fans. We believe that in the first half of Romance of the Three Kingdoms, you helped Cao Cao to start a business, and in the second half, Zhuge Liang helped Liu Bei succeed. If you don't die, you will surely defeat Zhuge Liang and unify the Three Kingdoms. Why Guo Jia is so popular puzzles me. The more counselors see, the more confused they are. We will discuss this answer after reading Guo Jia's deeds.

First, Cao Guohui.

The plot described in Romance of the Three Kingdoms is this: Guo Jia was recommended to Yu Xun by Cheng Yu, and he said wryly, "I am ignorant and cannot be recommended by the public. A well-known person, surnamed Guo, Jia, filial piety, is a saint today. Why not give it to him? " Yu Xun patted his forehead and let out a cry. How can I forget him? So Guo Jia was recruited to Cao Cao's account. Guo Jia also recommended a descendant of Guangwudi School, Ye Liu, Chengde, Huainan. Since then, Cao Cao has established his own think tank or expert committee. Actually, it's not. At that time, Cao Cao died of love and wrote to Yu Xun for talent. Yu Xun recommended Guo Jia. 4 1 year-old Cao and 27-year-old Guo Jia talked for a long time. These days, young people are neither simple nor knowledgeable. Cao Cao sincerely admired, "If you want to be a big businessman, you must first have this person." Deeply impressed by Cao Cao's charm and bearing, Guo Jia said happily, "What a master."

At that time, Yu Xun was in charge of Cao Cao's internal affairs, Cheng Yu was guarding the city for Cao Cao, and Jia Xu and Ye Liu had not come yet. Around Cao Cao, there is indeed a lack of counselors. The existing counselors are all middle-aged, honest and steady, and their minds turn three times before speaking. Guo Jiaze is different. The young man has a high voice and a rich expression, but his speech makes sense. This is the kind of person I am looking for, and I like this kind of person.

Before that, Guo Jia had stayed at home for six years. In the past six years, the world has been in chaos, heroes and traitors have risen side by side, fighting in their own way, wars have continued, and the people have suffered. What Yuan Shao, Yuan Shu, Liu Biao, Gongsun Zan, nothing promising. If I want to find Guo Jia, I must find a real English master who will benefit me for life. I will never go out of the mountain until I see the situation clearly. Guo Jia is so conceited, and conceit is innate. When I was a child, Guo Jia didn't like fooling around with children, but liked talking to the elders in the village. His original ideas often make some old people feel ashamed. Once, a warlock from other places met little Guo Jia and talked with him for a while. He was taken aback. I think this child is the reincarnation of Jiang Taigong. From then on, Guo Jia had a nickname-"Little Taigong".

When Guo Jia was 20 years old, Guo Jia seldom chatted with old people. He began to make friends with people of insight and stay away from secular people. As the saying goes, "There are literati talking and laughing, but there is no Ding Bai." These "men of insight" should include Yu Xun, Xin Ping, Guo Tu and others. Guo Jia, like most talents at that time, initially defected to Yuan Shao, a powerful person. After Yuan Shao's talks with Guo Jia, he certainly didn't say, "If you want to make an orphan into a great cause, you must have this person." But he spoke highly of Guo Jia and was respectful to him. However, Guo Jia found that Yuan Shao himself was indecisive and incompetent, and it was difficult to achieve great things. In a word, he has a comprehensive and meticulous grasp of Yuan Shao's shortcomings. On one occasion, he chatted with Xin Ping and Guo Tu, counselors under Yuan Shao's account. He said that the wise judge the amount of the Lord, so they can do anything and achieve fame. Now, let me measure our master, Yuan Shao. He has a strong imitation ability, and the movements of Corporal Duke Zhou are well mastered by him. This is also the reason why many talents defected to him. But he collected a lot of talents, but he didn't use them seriously, or he couldn't use them. He collects a lot of things, but he can't distinguish between priorities. He received many suggestions, but he never came to a conclusion. I'll add that he collected a lot of military forces, but he couldn't deploy them correctly. In other words, although Yuan Shao is powerful, on the surface. Due to the lack of management ability, these resources will eventually become the burden of Yuan Shao. Mr. Xin, Mr. Guo, we should help Yuan Shao pacify the world and establish the hegemony industry. That's two words, no chance. The two said that Yuan was kind to the world, and many people returned it, but today it is the strongest. Our salary is very high now. Where can I find such a good job? Both of them want to sit back and enjoy success, but they are unwilling to take risks.

I'd rather not do it than waste time with you. Guo Jia resigned and went home to be an otaku. I haven't had a job in recent years, so I don't have to work nine to five. Life in Guo Jia is relatively free and unrestrained. Especially when friends come, they drink and chat all night. Later, Chen Qun sued Guo Jia, and it is estimated that "bad habits" were formed at this time. The two wanted to get a "long-term meal ticket" from Yuan Shao, and finally the whole family was killed. Don't underestimate Guo Jia, he is helping you both.

Second, taxation.

After Guo Jia reported for duty, the first thing he did was to follow Cao Cao to conquer Liu Bei in Xuzhou. In the name of revenge for his father, Cao Cao aimed to win Xuzhou in the south. To the north is Jizhou of Yuan Shao, and Cao Cao dare not even think about it. After a long journey, Cao Cao came to the city gate. He wants to drink and attack the city. Just as I reached out to clear my throat, I saw Guo waving his hand. What is filial piety for? Master, Liu Bei wrote to us for peace. He treated the enemy first and handled it properly. We can't categorically reject Liu Bei and rush to attack the city. In this way, Liu Bei will take strict precautions. Xuzhou is a big city, easy to defend but difficult to attack. On the contrary, we should be very calm and generous, let Liu Bei relax his vigilance and take the opportunity to win Xuzhou in one fell swoop. Yes, the army will return to the camp and discuss the siege again. No sooner had he arrived at the camp than Cao Cao heard a bad news. Zhang Miao and Chen Gong colluded with Lu Bu and ended their lair Yanzhou. Only Yu Xun, Cheng Yu and others held the three counties. Filial piety, we can't retreat, but Xuzhou? Master, we didn't attack the city today, which means we haven't fought Liu Bei yet. In this way, master, you write a letter to Liu Bei and sell it to him for personal feelings. We won't be late again. The Guo family just wanted to show off when the war stopped. Cao Jun worked hard day and night and will be back soon. On this day, he came to Mount Tai, a famous scenic spot. After carefully examining the terrain, Guo Jia said to Cao Cao, "This place is dangerous. I'm afraid there is an ambush, and our army can't get in. " Cao said to him, if I were Lu Bu, I would definitely lie in wait here. But Lu Bu is not me. Don't worry, it's okay. Cao Cao knew Lu Bu and Guo Jia knew the way of marching. After Cao Cao came back, he launched a life-and-death struggle with Lu Bu Army in the battle of Puyang. In the first round, Cao Cao's recruits were burned and suffered heavy losses. In the second round, Cao Cao lied that he was burned to death, set an ambush, lured Lu Bu to send troops, and finally defeated Lu Bu.

In the process of recruiting Lu Bu, Guo Jia deeply admired Cao Cao's military talents, and Cao Cao also learned Guo Jia's extraordinary views on the art of war. They worked closely together and became bosom friends. Cao Cao appointed Guo Jia as the drink offering of Sima. In the first year of Jian 'an (196), Liu Bei was defeated and defected to Cao Cao. There are two different opinions on the handling of Liu Bei: Yu Xun and others suggested that Liu Bei should be removed early, while Guo Jia advocated that Liu Bei should be kept. Later, Liu Bei took the opportunity to betray Cao Cao and became a powerful opponent of Cao Cao. Liu Bei was killed, Sun's forces were isolated, and Cao ruled the country. So many people think that Guo Jia's proposal is wrong. Guo Jia's reason is that Cao Cao is recruiting the best soldiers in the world at present, and he is afraid that they will not come. Today, a Liu Bei finally came. He is not wrong. If Liu Bei is killed, others will think that Cao Gong doesn't love xian, or even harms xian. A wise man will be afraid of Tso and hold back when he hears this. So, who will you live in peace with? Cao Cao thought that Guo Jia was right, so he let Liu Bei go and told him not to be afraid, to grow vegetables well and not to be stolen.

There are many reasons why Cao Cao did not kill Liu Bei. First, Liu Bei has only two people, belonging to the "three noes". He has no territory, no army and no military exploits, that is to say, he has no strength and will not pose a threat to himself. Second, Liu Bei helped Cao Cao to annihilate Lu Bu. Instead of hurting Cao Cao, he actually helped Cao Cao. How can Cao Cao bite the hand that feeds him? Third, Cao Cao once killed the frontier. Unexpectedly, this incident aroused the anger of Yanzhou officials and people, and his good friend Zhang Miao and others rose up against him. This is the lesson of Cao Cao's killing celebrities. Fourth, Cao Cao underestimated Liu Bei's ambition and failed to see through Liu Bei's repetitiveness. He took over Pi for Liu Bei, captured Lu Bu alive, married his wife and children and returned, and named Liu Bei as Yuzhou Shepherd and Zuo General successively. It can be said that he is very kind to Liu Bei, but he just wants to buy Liu Bei, hoping that Liu Bei can serve himself wholeheartedly. Fifth, as Guo Jia said, build the brand of Liu Bei and recruit talents from all over the world. When Cao Cao and Liu Bei were cooking wine to discuss heroes, Liu Bei said many names. Cao Cao was not strong at that time. He hopes that these people can see their sincerity to Liu Bei and submit to themselves. Finally, Liu Bei is very good at being a man. He has his tail between his legs. Let Cao Cao find no flaws and feel no threats or inappropriate places. Therefore, there are multiple considerations for not killing Liu Bei. There is nothing wrong with Guo Jia's suggestion, but at the same time, Guo Jia said a word to Cao Cao: "It is early to fight the enemy for a long time." That is to say, Guo Jia suggested that although Liu Bei should be retained, we should guard against Liu Bei, restrict his freedom and prevent him from escaping.

But Cao Cao was deceived by Liu Bei's hypocritical appearance. In the fourth year of Jian 'an (199), Liu Bei successfully persuaded Cao Cao to go through the customs and attack Yuan Shu in the north. Then Liu Bei sent someone to kill Che Zhou, the secretariat of Xuzhou, and occupied Xuzhou. At this time, in the fifth year of Jian 'an (200 years), Cao Cao and Yuan Shao confronted Guandu, and they were inextricably linked. He sent Liu Dai and Zhong Wang to conquer Liu Bei, but he was defeated by Liu Bei. If Liu Bei and Yuan Shao unite, Cao Cao will have no peace. In particular, the front line of Guandu is in danger of being breached at any time. Cao Cao stroked his beard and couldn't eat. Seeing Cao Cao pull a long face, Guo Jia said, I know Yuan Shao very well. Whenever something happens, he is suspicious, so he can't decide anything quickly. It's not impossible for him to sneak up on us, but he thinks about it. It is estimated that there will be no movement for a month. Liu Bei, who has just occupied Xuzhou, has not had time to buy people's hearts and gather strength. If we advance to Xuzhou overnight, Liu Bei will fail. No worries, we can fight Yuan Shao to the death at the front. So, Cao Cao took the crusade. When Liu Bei heard about it, he ran away without any resistance, leaving his wife and children behind. Guan Yu was captured and used in the battle of Guandu.

Third, levy Lu Bu.

In September of the third year of Jian 'an (198), Cao Cao went to Xuzhou to fight with Lu Bu again. With the help of Chen Gong, Lyu3 bu4 defended closely and effectively blocked Cao Cao's attack. Time away from home is getting longer and longer. Yuan Shao and Zhang Xiu don't know if they will get into trouble for themselves, so Cao Cao has the intention of withdrawing from the army. Never go back, Guo Jia said. Lu Bu was brave before the war. Now he has lost three games in a row, and his arrogance has long been put out by us. Lyu3 bu4 frustrated, military forces will be totally embarassed. Indeed, Chen Gong of Lu Bu is still very clever. But in the face of difficulties, it is estimated that he may not have no good ideas. We can't wait for Lu Bu to restore morale, nor can we wait for Chen Gong's advice. He quickly led the army to attack quickly and defeated Lu Bu in one fell swoop. "Cao Cao said, this is the reason, but we have used the method, what else can we do. Of course there is a way, otherwise I wouldn't advise you to break through Xiapi City, which is just around the corner. Is it definitely the water of interpretation and sight? Yu Xun interjected. That's right, Guo laughed. Great minds think alike. So Cao Cao ordered the sergeant to decide the water of two rivers, and both Lu Bu and Chen Gong were captured and killed. This is the first victory and great victory since Guo Jia assisted Cao Cao. After four years of tossing with Cao Cao, the most powerful Lu Bu almost escaped under Cao Cao's nose. Due to Guo Jia's dissuasion, Cao Cao eliminated a great disaster and gained a big state.

Fourth, the theory of ten wonders

One day, Guo Jia came to see Cao Cao with a letter. This letter was written by Yuan Shao. The letter said that I would send troops to attack Gongsun Zan. Please lend me food and troops at once. The letter is full of arrogance, as if ordering subordinates. The borrower is still honest, not like a request, but like a threat. Cao Cao was very angry with this letter. Yuan Shao, Yuan Shao, you have more horses than me, and your territory is bigger than mine. You are better than me, and I will kill you sooner or later. However, I can't destroy your capital. Thought of here, cao cao and some depressed. Guo Jia said, master, you have this capital. And much more powerful than Yuan Shao. Really? Where is it? Master, do you remember one time when we sent troops to conquer Zhang Xiu, and your war horse was frightened and destroyed a large wheat field? At that time, you asked the marching master book to put forward the charge of practicing wheat and punish it according to military law. At that time, I finally stopped you. You cut your hair and replaced it with military law. At that time, I thought you had the potential to defeat Yuan Shao. Cao Caoxin said, it's a good thing you stopped me. Otherwise, how can I step down?

Through this matter, I think you are superior to Yuan Shao in ten aspects. Salt is complicated, the public body makes nature, and this way wins; Salt to counter-action, public to shun rate, this righteousness wins; Salt with leniency, public with fierce correction, this governance wins also; Wide outside and taboo inside, many relatives, simple outside and bright inside, can choose talents. This is also a victory. Seek less, seek more, and the public will do what they want, and this will win; Shao specializes in reputation, and being honest with others is also a victory; Salt T-shirts are known far and near, and everyone is concerned about them. This benevolence will win; If Shao is confused, open infiltration is not enough, which is an obvious victory; Shao is confusing right and wrong, and the public law is strict, and this article will win; Salt is an empty potential, I don't know what the soldiers want, the public is not as good as the public, and the soldiers are like gods. So is this Vu Thang.

Master, don't be afraid of Yuan Shao at all. He is a paper tiger. Morality, politics, understanding, benevolence, civil and military, in order to encourage Cao Cao, Guo Jia turned five advantages into ten. Cao Cao clapped his hands and laughed: Is this all true? I think I'm better than Yuan Shao, too. I didn't expect the comments on filial piety to be so applauded. Guo Jia used to work under Yuan Shao, but now he works for Cao Cao. Coupled with Guo Jia's natural ability to judge people, he saw through both of them. To sum up this "ten wins" for Cao Cao, the first thing is to recognize Cao Cao from the heart and be glad of his choice. At the same time, it also contains encouragement and requirements for Cao Cao, hoping that he can keep this "ten victories" and complete the great cause of unifying the world. Tian Feng, Guo Tu, my old friends. My understanding of Cao Cao was limited before. Today, I already know what kind of wise Lord he is. You are still blinded by Yuan Shao, and I feel sorry for your future. Filial piety, I am very happy with what you said. However, how to deal with this letter. Master, although we have many advantages and Yuan Shao has many weaknesses, it is not the time to turn against him yet. We should encourage him to go north to Gongsun Zan. This is our chance. When he is far away from us, we can kill Lu Bu first. Cao Cao wrote to Yuan Shao that if you attack Gongsun Zan, I'm sure you can win. If you need the help of your brothers, I will help you. Yuan Shao has a beautiful nose. Cao Cao's strength is not strong. He is afraid of me and respects me. I'll let you live a few more days first. Yuan Shao sent troops happily. Where is Cao Cao? He also sent troops.

Verb (abbreviation for verb) pacify the North.

In the seventh year of Jian 'an (202), Yuan Shao died of illness. I've done all the stupid things in my life, and I'll never get another chance. Let me do one more stupid thing, so he made Yuan Shang his heir. Guo Jia heard the news and said, Yes, it is Yuan Shao's style. Master, Brother Yuan is in Jizhou now. If our army stormed, they would be unable to unite and it would be difficult for us to win. Instead, let's go back to the army. What do you mean, brothers kill each other We will see it soon. As soon as Cao Cao left, Yuan Tan and Yuan Shang started fighting. Cao Cao only conquered Jizhou one by one.

At this time, Guo Jia suggested that Cao Cao recruit and reuse many celebrities from Qing, Hebei, Youzhou and Sizhou to win the hearts of the people and completely consolidate the current control and resistance. Yuan Shao was defeated, not because there were not enough advisers, but because there were too many advisers. This is the best legacy left by Yuan Shao. Cao Cao took his advice, made the best use of his talents, and even reused Chen Lin, who had asked his eighth ancestor.

After Yuan Shang's defeat, he defected to Yuan. Cao Cao asked Wang Xiu, an old minister of Yuan Shao. Wang Xiu doesn't talk. Cao Cao's evaluation of him is really loyal. This is Cao Cao's mind. Cao Cao had to ask Guo Jia. Guo Jia said, I have a plan, you don't need a single soldier. There are too many General Yuan who have surrendered to us now to use. Let them work. Cao Cao agreed and immediately sent Jiao Chu, Zhang Nan, Lv Kuang, Lv Xiang, Ma Yan and Zhang Kai to attack Youzhou in three ways. The soldiers arrived and conquered them successfully.

Further on, it is the Fifth Ring Road. It's better to stop or pursue if you go too far. At that time, General Cao Hong reminded Cao Cao that Yuan Xi and Yuan Shang were defeated and would die, exhausted and went to the desert. Today I will lead the army to attack the west. If Liu Bei and Liu Biao take advantage of their weakness to attack Xudu, I can't help them, that would be a catastrophe. Please return to the teacher and don't make progress. Cao Hong's suggestion is very reasonable. When Cao Cao conquered Xuzhou, his lair was destroyed by Lu Bu. Now, it is really too far away from home. Liu Biao is far stronger than Lu Bu. Guo Jia, unceremoniously pointed out that the gentlemen were wrong. Why is this? Master, although he is a big country in the world, people in the desert, because of their remoteness, can't be equipped. Take advantage of it unprepared, strike it suddenly, and it will be broken. Besides, Yuan Shao and Wu Huan are kind, but Shang and his brothers still exist and must be eliminated. Liu Biao is a guest of conversation. Self-knowledge is not enough to conquer Liu Bei, heavy responsibility may not be mastered, and light responsibility may not be used. Although the virtual country expedition, the public has no worries.

Guo Jia's proposal has three advantages: first, the soldiers insisted on going straight and caught the enemy off guard. There are countless examples of such success, and they are all great victories. For example, Li Su entered Cai Zhou on a snowy night, and Aquamarine entered the fishing sea alone, which was basically influenced by Beiyuan carved from its roots. The commander-in-chief of these campaigns may have learned from Guo Jia's experience. Second, it is advisable to chase the poor bandits with the only remaining courage and completely cut off Yuan Zhigen. Brother Yuan still has some military forces, and both of them have some brains. After Cao Cao left, it is very likely that he will unite with Wu Huan, then gather the old people of Yuan family in Hebei, and then capture several cities. Third, I judge Liu Biao. This is a gamble. As long as he is a wise man, he should know who Cao Cao's next target is after taking care of Yuan Shao.

It is this party, Liu Biao himself, who doesn't know. In other words, he doesn't believe what others tell him. As long as Liu Biao has some brains, he should sneak up on Cao Cao's rear while he is away. Guo Jia thinks that while waiting, Liu Biao, who has no IQ, has no brain. Master, just go forward boldly and don't look back. When Cao Cao heard this, the word filial piety was justified, and the army looked forward and could not be wrong.

Before he left, Cao Cao ordered someone to set up a sign on the seaside road, which read: "This summer, the road is blocked, and we will do it in autumn and winter." On the surface, it is a road sign to order the whole army, but in fact it is to paralyze the enemy. The five-ring people read it and believed it. I just walked for two days when I met a sandstorm. The road was rugged and it was difficult for people to walk. From the generals to the soldiers, they were miserable, and they backed out one after another, and the marching speed became slower and slower. Cao can't stand it either. He asked Guo Jia what to do. At this time of Guo Jia, soil and water did not fall, has been lying on his sickbed, looking haggard. Cao Cao's tears came down. Be filial, because I want to level the desert, which will cause you to go through hardships and even get sick. How can I be safe? "

Guo Jia said, I have great kindness to the Prime Minister, although I can't report my death in case. As the saying goes, soldiers are expensive and fast, so marching in this way is not acceptable. The army should lay down its baggage, throw away its trench, light its soldiers and go straight to the enemy camp. In addition, please ask the guide to adjust the marching route. Cao Cao invited Tian Chou, who was familiar with the geography of Liaodong, and took a path to Liucheng (Chaoyang City, Liaoning Province). It took about twenty days.

From today's point of view, this distance is about 400 kilometers (less than 1000 miles). If it's an infantry, it should arrive in a week or so. Considering that part of Wu Hengda is cavalry, Cao Cao's infantry had to lead the way, and the cavalry could only lead the horse, so it was not easy to arrive smoothly. Cao Jun arrived at the White Wolf Mountain (now the Great Black Mountain in the east of Jianchang County) about 200 miles away from Liucheng. Yuan, Yuan Shang and modu chanyu found that they hastily assembled tens of thousands of cavalry. Cao Cao's men are already exhausted troops after 20 days' trek, while Er Yuan's men and Morton's men are familiar with the terrain, and they are ready to wait. Cao Jun has no advantage in numbers. If his command is unfavorable, he is likely to be annihilated in western Liaoning, because they have no retreat.

This is destined to be an encounter, a decisive battle and a fierce battle. Almost all of Cao Cao's leading soldiers went into battle, and Zhang Liao, Huang Xu, Zhang He, Han Hao, Shi Huan, Xian Yushu, Yan Rou and Cao Chun fought bravely for the first place. In the scuffle, Cao Chun's butch was beheaded riding "Sheng Han Tatun". Wu Huan was leaderless and was finally killed to pieces. "Death in the Wild", the main cavalry of Wuhuan in the three counties began to collapse in this decisive battle. Wu Huan people were moved to the mainland by Cao Cao, and Wu Huan completely declined. Yuan and Yuan Shang escaped with thousands of people. If Cao Cao doesn't March thousands of miles, how can Cao Cao's defenders resist when tens of thousands of troops from Yuan, Yuan Shang and Morton return to Youzhou?
