The monarch of Shu was incompetent, neglected political affairs, attached importance to eunuchs, and did not strive for progress. The internal contradictions in Shu are sharp, loyal ministers are not reused, and important ministers such as Jiang Wei have been killed many times. Economically, since Zhuge Liang's death, the economy has been depressed and there is a shortage of soldiers. Food and grass are poor. Militarily, the military strength of Shu and Wei is indeed far from each other. The qualities of military generals vary greatly. Except for a few heroes like Jiang Wei, most of Shu are old ministers, which is not very good. Although there is a geographical position to defend under Wei's attack, it will eventually perish. Wargo's raiders, Zhong Hui's male army, surrendered without fighting under the condition of being surrounded, and Shu finally perished.

Wei Guofang

The main reason: 1 Wei occupied the Central Plains. It has a large population (accounting for two thirds of the country). And there are many talents and abundant labor resources. The economy is developed and the people want it. 2 In the early days of Wei Jianguo, Cao Cao held the Emperor to make the vassal's strategic policy correct. A large number of talented people defected to Cao Cao, and most of the people under Emperor Gaozu were also used by Cao Cao, such as Huang Xu. Secondary reasons: 1 Cao Shi family's great talent. Needless to say, Cao Cao (mainly in the early stage). As for his descendants, although they are many times behind him, they are enough to protect the country he laid. The terrain of the Central Plains is relatively stable. We can quickly mobilize troops to support, and food can be mobilized freely. 3 The emergence of Sima family. Sima's family has repeatedly broken Shu to destroy the Central Plains.

Shu

Shuni virus

The main reasons are: 1 is located in a remote place, with extremely underdeveloped traffic and a small population. Located in barbarians, there are few talents and insufficient troops. Only one-seventh that of Wei. The incompetence of the late master. If Zhuge Liang hadn't died, Shu would have perished long ago. (In fact, there is also a saying that Zhuge Liang does not attach importance to the cultivation of Liu Chan, but does everything himself. ) Jingzhou lost, Liu Beixin lost, which was a heavy blow and the political situation was chaotic. It will take many years to recover. But it also led to Zhuge Liang's birth only from Qishan. Huang Hao, Chen Zuo and others messed up the state affairs, making the court unstable. The ancients said, "If a soldier is outside, he must be inside first." The imperial court is uneasy. How long will the day of national subjugation last? 5 Qiao Zhou erred in his country and advocated surrender. Secondary reason: 1 failed to do its best. There were not many outstanding political talents when the eunuch Huang was in chaos. Zhuge Liang fought for the country all the year round, which overwhelmed the people and lost their hearts. The weather was bad for three days and there were many excellent opportunities, which Shu missed. The cooperation with Wu is not close, and both sides have never won at the same time. Zhuge Ke was even more proud, and Wu's last Northern Expedition was destroyed by him, which greatly weakened Wu's strength.
