First of all, how good is Guo Jia?
Guo Jia made his debut very early, when he was sixteen or seventeen. He went to Yuan Shao first, and found that Yuan Shao was "understaffed and resourceful", which was difficult to achieve in Wang Ba, so he resigned and retired to concentrate on his practice. Later, under the recommendation of Xun, Cao Cao invited Guo Jia, who was 2 1 year old, down from the mountain, and he was very valued from then on.
After analyzing the world situation, Guo Jia first suggested that Cao Cao attack Lu Bu and Liu Bei. As a result, Cao Cao adopted AD 198, and Cao Cao besieged Lu Bu, but Lu Bu failed to hold it. The battle lasted for half a year. Just as Cao Cao was about to give up, Guo Jia saw the chance of winning, and put forward the view that "a brave man has no plan, but he will fish after exhausting his resources" and advised Cao Cao to attack urgently. According to Guo Jia's plan, Cao Cao finally captured and killed Lu Bu alive.
In 200 AD, when Cao Cao led an army to compete with Yuan Shao, Cao Bing was weak and lacked confidence. So, Guo Jia hit the nail on the head and put forward the famous theory of "ten wins and ten losses". Guo Jia's analysis gave Jun soldiers a shot in the arm, and soon the army was greatly encouraged.
Cao Cao and Yuan Shao were at loggerheads in Guandu. In order to prevent Liu Bei from Xuzhou from attacking from behind when fighting Yuan Shao, it was decided to destroy Liu Bei first. As a result, all the soldiers are worried that Yuan Shao will take the opportunity to attack many capitals. Cao Cao was undecided about this, and Guo Jia stood up and said, "Yuan Shao has always been indecisive and will not respond quickly." As a result, Cao Cao followed Guo Jia's advice, and Liu Bei and Yuan Shao "stayed put".
At the same time, Cao Cao was afraid of Sun Ce when he was fighting in Guandu, but Guo Jia predicted that Sun Ce would soon die on the head of an assassin. As a result, the bully was really countered.
Later, Cao Cao defeated Yuan Shao in the battle of Guandu. Yuan Shao was furious and died of illness, and the two sons split up to compete for the heir. Cao Jun's generals thought he should be killed when he was ill. Only Guo Jia shook his head to stop it, urged Cao Cao to release the news, pretended to attack Liu Biao south, and then killed a comeback after fighting among himself, and World War I was pacified. After Cao Cao adopted it, the result was as Guo Jia expected.
Later, Cao Cao decided to make a long-distance expedition to Wuhuan, and Guo Jia put forward the idea of "blitzkrieg" attack, suggesting that Cao Cao take it lightly and take it by surprise, aiming at Khan Pavilion. Sure enough, you fell from the sky and defeated Wuhuan's people.
However, going to the Fifth Ring Road became Guo Jia's swan song, and Guo Jia, who was only 28 years old, died heroically in triumph. Coincidentally, in the same year, Liu Bei invited 27-year-old Gu.
Before Zhuge Liang came out of the mountain, he devoted himself to Nanyang, plowing in the rain, studying in the rain, and competing with the world for profit. After Guo Jia's death, Zhuge Liang came out of the mountain immediately, so there is a famous saying that "Guo Jia will not die, Wolong will not die".
In fact, these eight words should be understood in two. First of all, Guo Jia's talent is obvious to all. If he died early, with his intelligence and ingenuity, Cao Cao would certainly not have suffered the tragic death of Battle of Red Cliffs, which is why Cao Cao cried bitterly after the defeat in Chibi. He cried and said nine words: Guo Fengxiao is here, so he won't be lonely. These nine words tell the true knowledge level of Guo Jia, whose strategy is absolutely top among the three countries.
Secondly, Zhuge Liang's talent is obvious to all. After Zhuge Liang went down the mountain, he helped Liu Bei, who was poor and homeless, to become the overlord step by step, which is the best proof. However, the year when Zhuge Liang went down the mountain happened to be the year when Guo Jia died of illness. Although this is a coincidence, from another point of view, if Guo Jia hadn't died, Zhuge Liang really wouldn't have to go down the mountain, because the result of going down the mountain or not is the same, which doesn't stop Cao Cao from dominating the country. So "Guo Jia can't die, Wolong can't die" is not an exaggeration, but a fundamental one. Guo Jia's early death is a lifelong regret of Cao Cao.
Of course, in addition to the sentence "Guo Jia will not die, Wolong will not get out", there are actually eight words behind it: "Kongming's Northern Expedition, Crane Lake will rise."
"Kongming" of course refers to Zhuge Liang, but who is Zhuge Liang? Actually, it refers to Sima Yi. So, does Zhuge Liang's Northern Expedition have anything to do with the rise of Sima Yi?
The answer is yes.
Knowing that Sima Yi is a talented person, the so-called "ascetic monk" is too angry. Cao Cao smelled an ominous smell when he was alive, so he warned his successor Cao Pi before he died.
Of course, Cao Pi was wary of Sima Yi, but Sima Yi was good at putting on a show and offering "loyalty" in various ways. Later, Cao Pi trusted him and entrusted him with an important task.
After Cao Pi's death, his son Cao Shou succeeded to the throne of Wei Mingdi in 1860. As a result, just about two years after Wei Mingdi succeeded to the throne, Zhuge Liang of Shu Han started his first Northern Expedition when Cao Wei, a new king, succeeded to the throne and the political situation was unstable. Then Zhuge Liang made six northern expeditions to Qishan in his later years in order to achieve the goal he set in Longzhong: to revive the Han Dynasty.
Knowing that he couldn't do it, Wei sent many famous soldiers to resist Zhuge Liang's Northern Expedition, but the effect was not satisfactory. Especially after the death of Cao Zhen, the patron of Cao Wei, Wei could not find any outstanding generals. In the end, Cao Suo had no choice but to use Sima Yi who had been "hiding in the snow".
During the national crisis, Cao Cao didn't care so much, but he still used Sima Yi. As a result, Sima Yi successfully stopped Zhuge Liang's Northern Expedition with the tactics of "guarding", "waiting" and "dragging". In addition, the Shu army was affected by the problem of grain and grass. As a result, Zhuge Liang failed to go out of Qishan seven times and finally died of illness.
It was also because of his achievements that Sima Yi's official position soared, and later he was officially worshipped as a hero by Qiu. Qiu, one of the three public officials, has great power and is the highest military officer in the Tang Dynasty.
Holding the military power and worshipping Cao Cao as an orphan after his death, Sima Yi's prestige and influence are far from what they used to be. Even if he is excluded by Cao Shuang in the future, it will not affect his prestige. Sima Yi deceived Cao Shuang and others by pretending to be sick, and finally launched the Gao Ping Ling incident, which easily cleaned up Cao Shuang. At this point, the power of Cao Wei fell to Sima Yi, and the Cao Wei regime existed in name only. The Three Kingdoms also changed suddenly, Shu and Wu perished one after another, and Sima Yi's descendants unified and established the Jin Dynasty, which turned a new page in history.
