We believe that with Zhuge Liang's wisdom, we can't help but know that the strength of Shu Han is weak and the Northern Expedition is not easy to succeed, but Zhuge Liang chose to do so. He really doesn't know what consequences this will bring to Shu Han? In fact, of course he knows, and he knows very well, so why did he choose the Northern Expedition regardless of everything?
First, Zhuge Liang's high confidence. Zhuge Liang must be very aware of the strength gap between Cao Wei and Shu Han, but he dared to take the initiative to provoke Cao Wei because he had strong self-confidence. After all, it has never happened less in the history of defeating the strong with the weak. For example, in the Battle of Pengcheng, Liu Bang's allied forces totaled 560,000 * *, while Xiang Yu had only 30,000 troops. But as we all know, in the end, Liu Bang, with a large number of troops, was defeated by abandoning his helmet and armor, while Xiang Yu won with 30,000 troops. Therefore, sometimes more troops may not necessarily win a war. On the contrary, the weak may not have no hope of winning. Zhuge Liang, who has always claimed to be Le Yi in Guanzhong, certainly feels that his talent is extraordinary. It is possible to defeat the powerful Cao Wei through his own wisdom, but he happened to meet Sima Yi, who was evenly matched.
Second, the gap between the development speed of Wei and Shu. In addition to Wei's power, it is also very terrible for me that Cao Wei is developing faster than Shu. Although Shu Han established his own country, only Yizhou remained, and Cao Wei occupied more than half of the world, with nine states.
It turned out that it was already behind Wei. If you choose to recuperate, even if Shu Han can become stronger step by step, the development speed of Cao Wei is several times that of Shu State. The longer the time goes on, the greater the gap between the two countries will inevitably become. Then, at that time, I'm afraid there will be no chance to continue, because Wei is too strong, and dealing with one is as simple as stepping on an ant. So Zhuge Liang saw this, and he had to continue the Northern Expedition in an attempt to level the gap in the process of confrontation between the two sides, so as not to be left too far by Cao Wei.
Third, the successors of Shu Han are lacking. Zhuge Liang had reached a certain age at that time. If one day he dies, he is worried about who can take over his heavy responsibility. The answer is that no one can. For example, his appointed successors, such as Jiang Wan and Fei Yi, are not as good as Zhuge Liang himself in all aspects. So in the face of the failure of the Northern Expedition, Zhuge Liang had no choice but to start again and again. Because he knew that after his death, no one would be qualified for the job.
This is why Fei Yi later said to Jiang Wei, "We are not as far away as the Prime Minister. The prime minister still can't decide midsummer. What about us! " It turns out that this is true. Later, neither Fei Yi nor Jiang Wei performed as well as Zhuge Liang. Therefore, after seeing that there were no successors, Zhuge Liang knew that the chances of victory in the Northern Expedition were getting smaller and smaller, and insisted on the Northern Expedition again and again, because he knew that if he died, the chances of success in the Northern Expedition would be even more slim.
