Zhuge Liang's five northern expeditions shocked Wei Guanzhong. Why did Wei destroy Shu first?

Wei first destroyed Shu because Shu was the weakest country, with political chaos and was not good at fighting on water.

After the change of Gaoping Mausoleum, Cao Wei people were uprooted by Sima Yi and his son. Since then, the military and political families have been dominant, and the ruling power has become increasingly stable. After Si Mazhao succeeded to the throne as a general, he was hated by Wei Emperor Cao Mao because of his arrogance. Cao Mao secretly made friends with ministers and planned to personally crusade against Si Mazhao, but things got out and were killed by Si Mazhao's men. Although Si Mazhao was autocratic, he could not stop all the scholars in the world. In order to shift its focus, Si Mazhao urgently needs foreign wars to enhance its prestige.

Shu and Wu have lost their original firmness? Sun Liu Alliance? And Wei could not form a strong potential, and then Wu just wanted to live a happy life by relying on the natural barrier of the Yangtze River. Only Shu Han always threatened the western part of Wei, which also made Wei focus on Bashu. At that time, Wei was also sober. As long as Shu is destroyed and the three pillars stand on their feet, Wu is naturally assured. 、

After Liu Bei's death, Zhuge Liang was left behind to help his son Liu Chan. When Liu Chan first ascended the throne, Shu's national strength was basically exhausted, leaving only a mess for Zhuge Liang to clean up. Zhuge Liang had no complaints about this mess at all and began to develop the economy of Shu in a down-to-earth manner. First of all, Zhuge Liang first repelled the five enemy troops who came to take advantage of the fire to rob the border, making it peaceful. Then, Zhuge Liang made up with Wu and fought Wei. After this, diplomacy is basically solved, and the rest is domestic.

First, Shu is the weakest country.

We say that after Zhuge Liang's five northern expeditions and Jiang Wei's nine northern expeditions, the population of Shu and Han in the Central Plains dropped sharply. According to historical records, there are 900,000 militiamen in China, which is equivalent to 10 soldiers. It seems a lot. But pay attention to the ten people here, including the elderly, women and children, and all kinds of exorbitant taxes and miscellaneous fees. People in Shu are really miserable.

Shu is the most chaotic country. We often say that Shu divides people into several classes. First, northerners followed Liu Bei first, Jingzhou followed Liu Bei like Shu, third, Yizhou, and fourth, South China. These people's conflicts of interest cannot be adjusted. Zhuge Liang temporarily suppressed these contradictions with his own example and constant Northern Expedition. After Zhuge Liang's death, these contradictions spread and expanded rapidly until the end of the Shu-Han Dynasty. The ministers of the three kings have the biggest differences of opinion. We say that the most important leaders of Shu Han, from Liu Chan and Zhuge Liang to Liu Chan and Jiang Wei, have always had differences. Reflected in the death of Zhuge Liang, Liu Chan immediately stopped the Northern Expedition and did not allow people to build temples for Zhuge Liang. When Jiang Wei was framed by eunuchs, he could not be asked to run a farm to avoid getting into trouble.

Cao Wei is not good at water warfare. We say that the water war has always been the fatal wound of northerners like Cao Wei. Compared with the vast sea of Soochow, the cliffs of Shu Han are more acceptable to northern soldiers. Moreover, as long as he was captured, Cao Wei had a new way to destroy Wu. Why not fight on land? In fact, we have long known that the unification of Shu and Han and the fall of Jingzhou are extravagant hopes for them. I think it really doesn't matter who is unified as long as the people can live a good life.
