According to the biography of the Three Kingdoms Wei Yan, Wei Yan "went to Shu with his predecessor in the trilogy". In other words, he was originally a subordinate of Liu Bei, not a general, so Zhuge Liang's so-called anti-bone theory did not exist when he surrendered. Moreover, in the period of Liu Bei, Wei Yan was once entrusted with an important task. When Liu Bei was promoted to the king of Hanzhong, he abandoned Zhang Fei and Wei Yan as "Hanzhong satrap". It was interesting when Liu Bei announced the appointment letter. When he was a minister in the imperial court, he said to Wei Yan, "I give you such an important task now. Tell me, what would you do? " Supposedly, Liu Bei must have talked to Wei Yan first in private, and Wei Yan must have fought with him. Now there is this question, which should be out of consideration for Wei Wei. Wei Yan's answer shows his self-confidence or arrogance: "If Cao Cao personally leads all his troops to attack, because he will stop him for you, if he only sends a general with 10 thousand men to attack, I will eat him for you." (If Cao Cao comes from all corners of the country, please refuse for the king; For hundreds of thousands of people, please swallow it for the king. ) "guarding Hanzhong, he practiced his grandiloquence. Liu Bei didn't mistreat him either. He was appointed as the general of Zhenbei, and in the first year of lite, he made Hou Ting his capital. It is enough to say that you are blessed. You know, Zhuge Liang has been in charge of Liu Beifang's military and political power since he came out of the mountain. We can fully believe that Liu Bei must have consulted Zhuge Liang for these appointments and won his support. In fact, Zhuge Liang was very kind to Wei Yan. According to Pei Songzhi's note, Zhuge Liang once said to Wei Yan and others when he was ill, "After I die, you just have to watch carefully and don't send troops again. After I die, but be careful not to come back. ) "and also let Wei Yan act as his own authority. What kind of trust is this? Zhuge Liang will give power to those who think they have anti-bones? Many people caught Zhuge Liang when he was sentenced to death and did not let Wei Yan be present. They only believe that Yang Yi rejects Wei Yan. Does Zhuge Liang believe Yang Yi? "The Three Kingdoms of Fei Yi" said: "Wei Yan and Yang Yi contend. Every time we sit together to discuss things, we are not convinced of each other. They are always quarrelling. Wei pointed a knife at Yang Yi and scared Yang Yi to death, and tears could not stop flowing. Wei Yan, a value strategist, and Yang Yi, who has a long history, hate each other. Every time they sit side by side, they argue, delay or raise their knives to imitate musical instruments, which are sobbing. "Between Wei and Yang, Zhuge Liang obviously has no problem of favoring anyone." "Biography of Yang Yi" has a saying: "Life is clear and narrow." He has seen through Yang Yi. However, Zhuge Liang is also a talent. He took a fancy to Yang Yi's talent, and Yang Yi was a military staff officer at that time. Of course, he was there. Wei Yan is a striker, and his position is at least ten miles away from Zhong Jun, so he can't always be around. Besides, it is estimated that Zhuge Liang died suddenly, so his absence is natural, and there is no problem that Zhuge Liang deliberately arranged. Of course, we should admit that Wei Yan is different from Zhuge Liang in the choice of military strategy. This is actually not surprising. It is not surprising to say that Zhuge Liang was on guard against Wei Yan. As the commander-in-chief of the army, it is impossible for such a troubled world full of political power and conflicts of interest not to leave a hand for the generals with real power in the army and improperly restrain them. And in my opinion, Zhuge Liang later chose the strategy of "attacking and defending", which was really a last resort. There is no way out. Jingzhou fell and Wei's political situation was basically stable. Originally, the plan of "when the world changed, a general led Jingzhou soldiers to Wan and Luo, and a general led Yizhou soldiers to Qinchuan" has completely lost its possibility. In other words, it is only a matter of slogans to seize the world and revive the Han Dynasty. It never occurred to him to hit Xuchang. But these can't be humanitarian to outsiders. Wei Yan obviously didn't know these things, so he always suggested that "all soldiers should be invited to meet Tongguan in different ways with bright lights, such as the story of Han Xin". Zhuge Liang certainly wouldn't do such a risky thing, because with the strength of Shu, he could only beat about the bush and fight local wars, but he really couldn't go far, because he really couldn't "compete with the former." In addition, Wei Yan was later pursued by Yang Yi (being pursued! Wei Yan has no strength to fight back at all, so his brother is very loyal to Shu! ) has nothing to do with Zhuge Liang, but with Wei Yan himself. He was too arrogant and self-righteous in the "era of the last five tigers" in Shu. Zhuge Liang really can't be blamed for this disaster. It should be said that it is illogical not to comment on the stories in The Romance of the Three Kingdoms with the records in the official history. Because the romance of the Three Kingdoms and the official history are originally two Wei Yan and two stories.
