The old barracks mentioned in the title are some cultural relics unearthed in Narcissus County. Moreover, in 1986, some bronze seals were roughly excavated and identified as military seals in the Shu and Han Dynasties of the Three Kingdoms. Some weapons and equipment, crossbows and other ancient military buildings, including observation posts and beacon towers, were also found in pieces. Then experts come to the conclusion that Zhuge Liang's military feature is rigor! Then there is a lot of chatter about material supply, including battle plan and battle formation. In short, the conclusion is that Sima Yi cannot beat Zhuge Liang. In fact, this is unconvincing, and it is too old, and our understanding of history and monuments is still relatively small. Let's talk about why Sima Yi can't beat Zhuge Liang.
The first confrontation between Zhuge Liang and Sima Yi in history was the third time Zhuge Liang sent troops to the Northern Expedition. Since you Zhuge Liang hit me, Cao Wei, and we didn't resist, let's just attack Shu. Resist or cut Shu, so the two began to fight. As a result, Zhang He was killed. Of course, there are different records of his death in history books, so I won't explain it in detail here. The last time was at loggerheads in Wuzhangyuan. Everyone knows that Zhuge Liang is dead and the Northern Expedition is over. But Sima Yi's wrong tactic was to eat and sleep in the barracks and beat the landlord. You Zhuge Liang asked me to fight to the death, and I won't play with you. In this way, Sima Yi killed Zhuge Liang with the strategy of "don't stick to it, wait for merit".
Sima yi can't beat Zhuge Liang, and the strategy formulated by Cao Wei regime is "consumption"! It's like Zhuge Liang gambling with hundreds of thousands of Sima Yi with thousands of dollars, and Zhuge Liang always wants to play poker. Sima Yi is not stupid. I have a lot of money, so I will play with you one by one. What do you want from me? The same is true of the national conditions of the two countries. Zhuge Liang, too, bowed his head in everything, no matter how big or small. Caution is nothing to say. Even though Sima Yi could not beat Zhuge Liang, he was not defeated by Zhuge Liang strategically, which is why Zhuge Liang never touched the gate of Chang 'an in his life.
