You should know that running the country and running the army are two different things. Jiang Wei is very wise in fighting, but he is not good at governing the country. Otherwise, he will not repeatedly attack the strong country with weak countries, and finally leave the poem "Jiang Wei attacked the central plains nine times by himself".
After Zhuge Liang's death, Shu mainly relied on Jiang Wan, Dong Yun and Fei Yi, and Jiang Wei did not participate in governing the country.
Jia Chong and Shao Shao, the former as the founding fathers of the rulers, the latter as confidants, assisted Sima Shi in governing the country, and their ability to govern the country was naturally better than that of Jiang, who could only fight.
