Zhuge Liang was a famous military master during the Three Kingdoms period and a well-known historical figure. When Zhuge Liang chose to follow Liu Bei when he went out of the mountain, in fact, many things were already planned. As a strategist, the development path of Shu Han, in fact, Zhuge Liang had already made arrangements in his heart, although Guan Yu's loss of Jingzhou was an accident, but this could not disrupt Zhuge Liang's plan.
1. Xingfu Han Room
After Liu Bei claimed to be a Han dynasty, he was supported by the Han Dynasty, so he would receive the support of the people and win the hearts and minds of the people. But later Cao Pi had established himself as emperor and changed the name of the country to Wei. Therefore, the State of Shu and the State of Wei belong to the opposite side of the two countries, while Eastern Wu is different. Therefore, when the State of Shu wanted to be orthodox, the biggest enemy was still the State of Wei.
The capital of the Han Dynasty was first in Chang'an, and later moved to Luoyang, and there was never a single period in Shudi. Therefore, if you want to revive the Han Room, it is even more important to take back the capital of the Han Room.
2. Insufficient national strength
In the Battle of Yiling, the Shu state was defeated by Lu Xun and suffered heavy losses. At the same time, it also lost many excellent advisers and soldiers. People's hearts are scattered, and it is difficult to use troops on a large scale in a short period of time.
Soon after Jingzhou was taken, Sun Quan also adjusted the main officials of the three counties, and then directly moved the capital to Wuchang, strengthening control over Jingzhou, in order to prevent the Shu state from returning to retaliate, and then continued to seize Jingzhou, and even directly appointed Lu Xun as the governor to establish a defense, which greatly increased the strength of Jingzhou.
After the Battle of Yiling, Sun Quan sent an emissary Zheng Quan to convey the meaning of peace to the Shu state, so later the two countries were allies again. But at the same time, Wu Guo's precautions against the Shu State did not diminish at all.
Although it is said that after the Battle of Chibi, Cao Wei's losses were also very heavy. But in general, cao wei is always the strongest of the three countries. If Zhuge Liang only thinks that Jingzhou is too small, the final dispute between the two countries must have let Cao Wei pick up the cheap, and only by joining forces with Eastern Wu is the long-term solution.
3. There is no hope of going east, only north and south
After the shu state's plan to go east was shattered, it could only look at the north and south directions. Zhuge Liang first quelled the rebellion, and then quickly attacked the southern barbarians led by Meng Yu, causing the Territory of the Shu State to expand greatly to the south. It provided a sufficient foundation for the Northern Expedition, avoided internal contradictions, and set up seven counties in the south, so that the territory could be further explored.
It can be seen that no matter what, Zhuge Liang will not choose to be an enemy of Sun Quan. At any time, Cao Wei was their worst enemy, and if Zhuge Liang was only bent on retaking Jingzhou, it would only hasten the demise of the Shu state. Facts have also proved that as long as Shu Wu has always been in alliance, it is difficult for Cao Wei to make great achievements.
