Under this circumstance, the situation was of course extremely unfavorable to Wei Yan. Wang Ping scolded him before the battle: "The Duke is dead and his body is not yet cold. How dare you do it?" Wei Yan's troops were immediately shaken in morale. "Everyone knows that the song is in Yan, so don't In order to serve our lives, all the troops dispersed." In fact, the so-called "Qu Zaiyan" is also a superficial phenomenon. How can a soldier know the inside story of the struggle between the upper class? They only obeyed the orders of Liu Chan and Zhuge Liang. Since the emperor and the prime minister were on Yang Yi's side, it was normal for them to think that Wei Yan was rebellious and unwilling to follow him. In other words, what Wei Yan's men did has nothing to do with the rights and wrongs of the entire incident. In the situation where "all the troops were dispersed", Wei Yan had no choice but to "flee with several of his sons and run to Hanzhong. Yi sent Ma Dai to chase and kill them, and killed him." So Yang Yi stepped on Wei Yan's head and said mockingly: "A mediocre slave, can you do evil again?" After that, Yang Yi "Yi Yan three tribes". "Three Kingdoms" Volume 40 "Wei Yan Biography". It is a tragedy that the famous general Wei Yan died in this way. The internal strife between Wei and Yang ended with Wei Yan's complete defeat. Wei Yan's failure had subjective and objective reasons. From an objective analysis, Wei Yan was attacked and rejected by Zhuge Liang for many years, and coupled with the jealousy of Yang Yi, Fei Yi and others, he was in a difficult situation and was weak. From a subjective analysis, Wei Yan himself was confused during this emergency and handled it inappropriately. He should not have trusted Fei Yi easily, nor should he have burned down the "Pavilion Road" where the main force returned during the retreat, and taught others to "conspire against the enemy". It is even more inappropriate to "occupy Nangukou" and use thousands of troops to fight against Yang Yi's 100,000 troops. This is completely a matter of throwing eggs at stones and overestimating one's own capabilities. I think Wei Yan's character and talent are indeed very similar to Han Xin, that is, he is good at using troops and is a military wizard. But politically he appears naive and lacks wisdom and resourcefulness. Seven years after Wei Yan's death, Yang, a native of Shu, wrote "Ji Han Fu Chen Pian" and gave Wei Yan the following comments: "The text is long and rough, and he accepts orders when faced with difficulties. He breaks out against foreign troops to protect the country's borders. He is discordant and forgetful. Yang Xi affirmed Wei Yan's contribution to "defeating foreign forces and protecting the country", lamented that he could not start well and end well, and pointed out that the root cause was his "disharmony" and unruly nature. Untamed character, this evaluation is relatively fair. Finally, it needs to be pointed out that the so-called "rebellion" theory of Wei Yan is completely fabricated by Luo Guanzhong. Chen Shou had already made a conclusion on this: "Originally Yan intended not to surrender to Wei in the north but to return in the south, but he wanted to eliminate killing rituals and so on. The generals are usually of different temperaments. He hoped that the commentary on the time of Hebei must be based on Liang. This was originally meant to be so that it would be inconvenient to betray." "Three Kingdoms" Volume 40 "Wei Yan Biography". Ironically, Wei Yan's enemy Yang Yi seems to have "a bone in the back of his head." After Yang Yi killed Wei Yan, he thought that he had "great merits" and that he was the only one who could govern on behalf of Liang. Little did they know that Zhuge Liang had already made arrangements before his death, "because of his narrow demeanor and narrow temperament, he intended to target Jiang Wan, so Wan became the minister of law and the governor of Yizhou." The later master only gave Yang Yi a false title, "I worship him as the Central Military Advisor, he has no command, he is just calm." So Yang Yi complained: "In the past, when the prime minister was dead, if I had raised an army to attack the Wei family, I would have behaved in such a wicked way! It will make people regret it forever." These "treasonous and unethical" words were criticized by Fei Yi The consequences of secretly reporting to the empress can be imagined, so Yang Yi was deposed as a commoner. Yi "repeatedly wrote a letter of slander", so he was imprisoned and punished, and "Yi committed suicide". Although Yang Yi's death was self-inflicted, it was a pity after all because he was also a rare talent. During Zhuge Liang's Northern Expedition, "Yi regularly drew divisions to plan grain and grain harvests, without thinking about them. It was just a matter of convenience. Military military control was based on Yi." "The Chronicle of the Three Kingdoms" Volume 40 "Yang Yi Biography". . Shu Han was a small country and had much fewer talents than Wei and Wu. Zhuge Liang employed inappropriate personnel during his lifetime and was unable to coordinate the relationship between his subordinates. After his death, the Shu Han regime began to suffer internal strife, which made matters worse for Shu Han, which lacked human resources. , will inevitably accelerate the decline of Shu Han. Zhuge Liang bears unshirkable responsibility for this
