In fact, the root cause is strength. First of all, in terms of regional strength, Shu has only one state, while Cao Wei has ten States, which is completely at a disadvantage of one to ten! It is unfair to blame Liu Chan for the destruction of Shu. Before Zhuge Liang died, Liu Chan listened to Zhuge Liang everywhere. After Zhuge Liang's death, Liu Chan put Jiang Wan, Fei Yi, Jiang Wei and others in power. It should be said that employing people is correct, and these people are also called loyal to their duties. However, the gap between comprehensive national strength, especially economic strength, is still very large! Why did Shu's Northern Expedition fail many times, and the site that was laid down also needed to be forced to give up, because they could not accept the new site! Zhuge Liang and Jiang Wei's Northern Expedition was actually an offensive and defensive game, betting on the fate of the country. It was unwise for them to fight a war of attrition with Wei, and finally Shu was dragged down! It should be pointed out that the so-called strong talent lineup in Shu is one-sided! Influenced by the Romance of the Three Kingdoms, The Story of the Three Kingdoms and traditional Chinese opera, there is a general feeling of sympathy for Shu and hatred for other two countries. In fact, in terms of talents, Shu is not only weak in lineup, but also inferior to the other two countries! The most direct statement is that there is no general in Shu. Maybe you will say that there are five generals in Shu, but there are no five generals, only four generals. After the fall of Guan Yu, only Ma Chao and Zhuge Liang can be called great generals in Shu. Unfortunately, Zhuge Liang wants to be busy with government affairs. Ma Chao was ostracized by Liu Bei's old staff and died of depression soon. Although Zhang Fei and Huang Zhong are brave, the aggressive emotions in their personal personalities hurt them in the future! As for Zhao Yun, unfortunately, his position in history is similar to that of Dian Wei and Chu Xu. He is a guard captain, a general with a miscellaneous brand. There were almost no generals in the middle period, and all civil servants were generals, so Liao Hua was the pioneer (normally, Liao Hua was over 75 years old at this time). In the later period, it was only General Jiang Wei, but it was a pity that one tree was difficult to support! On generals, there is a big gap between Shu and other two countries! Paper officer, Shu is not much different from Wei and Wu. Except Zhuge Liang, Pang Tong died, Fazheng died early, Ma Liang was lost in Yiling, and Ma Su was lost in Jieting. The restoration of the Han Dynasty is only a dream. At that time, the situation was that the Han dynasty had fallen apart, which was beyond human power. Zhuge Liang and others are actually fighting against the fate of the times. How can they not fail? Therefore, he will have the sigh of "Man proposes, God disposes"! For example, Jiang Wei's plan to rejuvenate the country failed because of the unification of the general trend. Basically, the Liu Han family has been extremely decadent and lost the hearts of the people. Although Zhuge Liang and others (including Lu Su) put forward the strategic planning of Longzhong or similar projects, they all ignored the most important point, that is, the historical trend is irreversible. It is the people's heart that determines the direction of history! It is not always what they think. At the end of the Eastern Han Dynasty, the Yellow turban insurrectionary was in chaos, the court was corrupt, officials were sold and titles were given, and the people were in poverty. Who would long for such a day? ! Paying too much attention to personal factors and trying to fight against the general trend on your own are doomed to failure after all! Liu Chan was finally rehabilitated. He didn't disappoint people. He was just a mediocre man. What can he do? I'm used to living in splendor, and it's understandable that I hate complicated politics. Although Zhuge Liang could not revive the Han Dynasty, what could he do? No one can change the situation at that time! If you care about your life, you can't care about your life The early lineup of Shu was very strong, but these talents were not born and bred, but were snared by Liu Bei for half their lives. The years are ruthless, and the age is fading away. The future talent problem is a good proof!
