In the Romance of the Three Kingdoms, we saw Jiang Wei's wisdom, which made Zhuge Liang flee on the battlefield. This is rare, or it can be said that it is only this time. From this we can see that Jiang Wei's military thought is good. This is also one of the important reasons why Zhuge Liang chose Jiang Wei.
Second:
Jiang Wei was a general of Shu Han in the late Three Kingdoms period. At that time, he was skilled in martial arts and an outstanding talent under the background of talent shortage.
Third:
Jiang Wei was a military general on the Wei-Shu border and was familiar with the war environment. He is very similar to Zhuge Liang in fighting, so Zhuge Liang focused on him in his choice. There are few wise generals in Shu. Although Wei Yan is a general, his accomplishments in the art of war are not deep, and at the same time, he has not been reused by Zhuge Liang because of his anti-bone theory. Although Yang Yi has profound attainments in the art of war, her martial arts is poor and she can't replace him.
Zhuge Liang made a mistake here, that is, when appointing a successor, he ignored a problem, that is, Jiang Wei is not Zhuge Liang, and his personal prestige and resume are unconvincing, which is why Jiang Wei was misunderstood by Liu Chan in his later period and could not make a strong contribution.
Zhuge Liang's transfer to Jiang Wei seems to us to be a helpless move today, but it is a very good choice.
Zhuge Liang (181-23410-8) was born in Xuzhou (now yinan county, Linyi City, Shandong Province) and was an outstanding politician, strategist, diplomat, writer, calligrapher and inventor during the Three Kingdoms period.
In his early years, he went to Jingzhou with his uncle Zhuge Xuan. After Zhuge Xuan's death, Zhuge Liang lived in seclusion in Longzhong, Xiangyang. After Liu Bei arrived at the thatched cottage, Zhuge Liang was invited to come out, but Sun Lian resisted Cao and was defeated by Battle of Red Cliffs. Formed the trend of the Three Kingdoms and captured Jingzhou.
In the 16th year of Jian 'an (2 1 1), Yizhou was captured. Then he defeated Cao Jun and won Hanzhong. In the first year of Shu Zhangwu (22 1), Liu Bei established the Shu-Han regime in Chengdu, and Zhuge Liang was appointed as the prime minister to preside over state affairs. Liu Chan, the ruler in the last years of Shu and Han Dynasties, succeeded to the throne, and Zhuge Liang was made the marquis of Wuxiang, leading Yizhou as a shepherd. Diligent and prudent, big and small political affairs must be personally done, and rewards and punishments are strict; Make an alliance with Wu Dong to improve relations with all ethnic groups in southwest China; Carry out the reclamation policy and strengthen combat readiness. Most of the six northern expeditions to the Central Plains were based on grain.
Eventually, due to overwork, he died in Wuzhangyuan (now Qishan, Baoji, Shaanxi) in the twelfth year of Jianxing in Shu at the age of 54. Liu Chan made him a loyal minister, and later generations often called him Zhuge Liang by Wuhou. Because of his military ability, the Eastern Jin regime named him King Wuxing.
The representative works of Zhuge Liang's prose include A Model and A Book of Commandments. He once invented the wooden ox, the flying horse, the Kongming lantern and so on, and transformed the crossbow, called Zhuge Lian crossbow, which can hit all targets with one crossbow. Zhuge Liang is the representative of loyal ministers and wise men in China traditional culture. He devoted himself to his life and died.
Jiang Wei (202-264) was born in Jixian County, Tianshui (now southeast of Gansu Gangu). During the Three Kingdoms, Shu and Han were all famous generals, officials and even generals. When I was a teenager, I lived with my mother and liked the theory of Zheng Xuan, a Confucian master. Because his father, Jiang Tong, was killed in battle, Jiang Wei was appointed as Zhonglang by the county.
During Zhuge Liang's Northern Expedition, Jiang Wei was suspected of disloyalty. Jiang Wei had to surrender to Shu Han and was highly valued by Zhuge Liang.
After Zhuge Liang's death, Jiang Wei began to make his mark in Shu Han. After Fei Yi's death, Jiang Wei began to take charge of the military power, continued to lead the Shu-Han army in the northern expedition to Cao Wei, and fought against Cao Wei's famous wargo, Chen Tai and Guo Huai many times. Jiang Wei won the Northern Expedition twice. Small wins three times; Not four times apart; A big defeat, a small defeat. Later, due to the fact that Shu Zhong's ministers also opposed Jiang Wei's Northern Expedition and eunuch Huang Hao played politics, Jiang Wei could not be killed, so he had to reclaim land in the stack to avoid disaster. After five attacks on Shu, Jiang Wei defended Jiange and blocked Zhong Huijun, but Deng Ai attacked Chengdu from Pingyang and surrendered.
At the beginning, Liu Bei was the king of Hanzhong, leaving Wei Yan to guard Hanzhong, and leaving heavy troops in various garrisons to resist foreign enemies. If the enemy attacks Hanzhong, they can defend themselves from the customs and cannot enter Hanzhong. This is how Wang Ping resisted Cao Shuang's attack. However, Jiang Wei believes that although this method conforms to the meaning of "emphasizing the door" in the Book of Changes and can defend against the enemy, it cannot achieve great results.
It is better to let the enemy enter Yangpingguan, the Shu army retreat to Han and Le cities, and then send a large army to fight guerrilla warfare and attack the weak links of the enemy.
This can lengthen the enemy's supply lines, and it is impossible to obtain food and grass on the spot. If it lasts for a long time, when the enemy comes back exhausted, Zhucheng defenders and guerrillas will take the opportunity to attack together, so that the enemy can be wiped out. So Hu Ji, the commander-in-chief of Hanzhong, was ordered to keep Han Shou, Wang Han, the supervisor, and Jiang Bin, the supervisor, to keep Seoul, in case of a strong enemy, and surrounded Xi 'an, Jianwei, Wuwei, Shimen, Wucheng, Jianchang and Linyuan.
