Unlike Zhou Yu in the official history, Zhuge Liang still served Liu Bei as a formal strategist for a few years, but this time was not long, after Liu Bei had Pang Tong, Fa Zheng and others, Zhuge Liang mainly dealt with internal affairs and logistics matters, among which the most critical thing about Zhuge Liang's strategy was "Longzhong Pair"

[Zhuge Liang's strategic performance]

Although Zhuge Liang has not been a military advisor for a few years, he has also performed several times in strategy. Pen & Fun & Pavilion www.biquge.info After Liu Cong's betrayal, Zhuge Liang once persuaded Liu Bei to take the opportunity to seize Xiangyang and control Liu Cong to fight against Cao Cao, but Liu Bei refused, and later persuaded Liu Bei not to go to Jiangdong, but was rejected by Liu Bei again.

These two suggestions can be said to be very pertinent, Liu Cong surrendered to Cao Cao after coming to power, and lost the hearts of the people, it is desirable, even if in order to fight Cao Cao, it is no problem to seize Jingzhou to expand his power first, and then Liu Cong is still unkind, but it is a pity that Liu Bei does not take into account benevolence and righteousness. And Liu Bei's going to Jingkou was too risky, Sun Quan might imprison Liu Bei if he was not good, and Liu Bei himself admitted afterwards that he should not go.

In addition, when Zhuge Liang sent to Wu State, he also performed very well, he confused the alliance with the anti-Cao matter, so that Liu Bei could easily form an alliance with Sun Quan.

But there was controversy over Zhuge Liang's persuasion of Liu Qi to go out, and many people took Yuan Tan's failure to compete for the throne as an example, thinking that Zhuge Liang's move was inappropriate. However, the specific situation of the Yuan family and the Liu family in history is really different, before the death of Yuan Shao and Liu Biao, neither of them left a will to confirm their successors, and it is normal for the ministers under the Yuan family to recommend the eldest son Yuan Tan to succeed to the throne, and later it was not the trial and others who forged the suicide note, Yuan Tan is actually the heir of the Yuan family, but the ministers of Jingzhou did not recommend the eldest son Liu Qi after Liu Biao's death, but directly let Liu Cong come to power, Liu Qi was also in Xiangyang can not stay anymore Zhuge Liang persuaded him to go out, and Yuan Tan's situation is much worse, Yuan Tan was really cheated out, and Liu Qi actually couldn't stay.

Relatively speaking, Liu Cong's supporters in Jingzhou may be united with the Cao faction, so the power is strong, and it has even threatened Liu Qi's life, like Liu Bei was directly hunted down and killed because of his connection with the inheritance, so Xiangyang is not good for Liu Qi, and it is normal for Zhuge Liang to persuade him to go out. Yuan Tan's situation and Liu Qi's situation seem to be the same, but the specific analysis cannot be generalized.

Zhuge Liang's role as a military advisor was mainly in the early stage of taking refuge in Liu Bei, and in the later stage, he mainly dealt with government affairs, among which he was the best in terms of strategy, and it can be said that he was "Longzhong right".

[Revival of the Han Dynasty and the "Longzhong Pair"]

Historically, the Shu Han Group wants to dominate the world, I reviewed the possibilities, and I personally think that the only possibility is the "Longzhong Pair", as long as the Liu Bei Group does not deviate from the relevant strategy in the "Longzhong Pair", there is a great hope of defeating Cao Wei and reviving the Han Dynasty, but in other words, as long as the Liu Bei Group deviates from any point of the strategy in the "Longzhong Pair", the hope of reviving the Han Dynasty will be greatly reduced.

According to the strategy in the "Longzhong Pair", if everything goes well, in theory, Liu Bei can start from scratch, seize the world, and revive the Han family. The first step in this is to seize Jingzhou and Yizhou, at that time, Liu Bei sent people under the fence, and did not have his own territory, so Zhuge Liang first had to choose a foundation for him, this foundation land is Jing and Yierzhou, why these two territories, because compared to Cao Cao and Sun Quan, Liu Biao and Liu Zhang are much easier to deal with.

So is it okay for Jingzhou and Yizhou to be one less piece, no, both are indispensable to Liu Bei. Jingzhou is in the land of four wars, and in history, Liu Biao was trapped in Jingzhou because of conflicts in Jingzhou and the southeast and northwest, and his power became weaker and weaker, and he lost Nanyang County and part of Jiangxia territory successively. And only Yizhou can do it, no, Yizhou is easy to defend and difficult to attack, it is not easy to get out, and there is a lack of the most important political and military talents in troubled times.

Moreover, Liu Bei only had enough strength to suppress Sun Quan by occupying Erzhou, otherwise after the destruction of Wei, all he did was to make a wedding dress for Jiangdong.

"Longzhong pair" also repeatedly mentioned that it is necessary to unite Sun Quan and form an alliance with Jiangdong against Cao Wei, which is also very critical, after all, Jiangdong and Liu Bei are going to seize Jing and Yi Erzhou are in the south, Liu Bei and Cao Cao must keep the safety of the rear when they confront, and Sun Quan is either eliminated or wooed, and Jiangdong is strong and not easy to deal with, so if Liu Bei wants to defeat Cao Cao, he must encircle Sun Quan.

When Liu Bei did all this to stabilize the rear, the next strategy of "Longzhong" was to wait, wait until there was a change in the world and take the opportunity to seize the world. This word shows self-knowledge, you must know that even if Liu Bei occupies Jingzhou and Yizhou, and forms an alliance with Sun Quan, he does not have enough strength to swallow the strongest Cao Wei at that time, so Liu Bei wants to seize the world, it is not enough to develop his own strength, he also needs an opportunity.

And does Liu Bei have this opportunity in history? There really is! Cao Wei's change of day is a great opportunity, Cao Cao died before Liu Bei, and Cao ** did not receive any stimulation before, that is, according to the normal development Cao Cao died, and after Cao **, his son Cao Pi came to power, Cao Pi soon changed the dynasty, which is undoubtedly a great opportunity for the Northern Expedition.

Although Cao Pi was very arrogant after coming to power, although he himself was not a faint king, compared to his father Cao Cao and son Cao Rui, he felt that Cao Pi was the best bully, like Cao Cao, not to mention, Cao Rui could also become Qin Emperor Han Wu in minutes if he put a little pressure, and there was no good way for Zhuge Liang and Sun Quan to join forces to take Cao Rui in history. Although Cao Pi's ruling was relatively smooth, the root cause was that Shu Han and Sun Wu fell out, which gave Cao Wei a chance, Cao Pi did not have too strong persuasive power in military and economic aspects (the military defeat of Wu was not successful, and the economy was canceled five baht money), and Cao Pi also wantonly promoted relatives and generals as commanders, and it was difficult for generals with foreign surnames to come forward, which would undoubtedly weaken Cao Wei's military ability.

Sun and Liu's joint crusade against Cao Pi still has a great chance of victory, especially when Cao Pi has just come to power or changed the dynasty. In terms of time, Liu Bei also came in time to deal with Cao Pi, and if it went well, Guan Yu, Zhang Fei and others would not die.

From the above calculations, it can be seen that Zhuge Liang's "Longzhong Pair" is an absolute miracle, he can make Liu Bei, a person under the fence, have hope to seize the world, and it is indeed feasible, which is equivalent to helping a regional governor of China or India to dominate the world now, which is more powerful than helping China or India become the world hegemon.

The reason for Liu Bei's failure in history is that he finally completely deviated from the "Longzhong pair", Liu Bei failed to entrap Sun Quan, Guan Yu overestimated himself after the victory of the army, which made Liu Bei's group and ally Sun Quan turn against each other, and also lost Jingzhou, and further failed to grasp the opportunity to attack Wei, when Zhuge Liang took power, Shu Han was already in a side, Cao Rui was far more difficult to deal with than his father Cao Pi, Zhuge Liang worked hard, and finally he was unable to return to the sky.

Among the four pairs at the end of the Han Dynasty, "Jizhou pair", "Jiangdu pair", and "couch pair" are relatively unrenowned, far from being able to compare with "Longzhong pair", I can only express my convincing, like the frustrated "Jizhou pair" was the first to put forward the idea of "coercing the Son of Heaven and ordering the princes", and the proposal was also very comprehensive and correct, but it was not expected that Dong Zhuo of the Xiliang Army would die early, and the emperor would migrate in advance, only a fixed number was calculated, and Zhuge Liang's "Longzhong pair" basically counted both the fixed number and the variables, Liu Bei wanted to revive the Han Dynasty, it can be said that as long as it was in accordance with " Longzhong's strategy for "is on the line, and this kind of strategy is really unique, at least I haven't seen the second one.

Note: Many times, variables need to rely on luck, but Dong Zhuo's reign is obviously more problematic and less stable than Cao Cao's, so there are more changes, and this is not just a matter of luck.
