Zhuge Liang's 27-word last words probably mean: "Shu has many throat arteries in Sichuan and other places, but you don't have to worry too much about these roads, but the road is difficult and dangerous. Although you don't think anyone can walk this road, I think you must guard it well. Only by keeping this road can we save the Han Dynasty. "
Jiang Wei didn't forget that Sima Yi was better. In fact, Jiang Wei is also a general. He didn't forget Zhuge Liang's last entrustment, but Si Mazhao also grasped it. Jiang Wei made a wrong decision when faced with a very difficult predicament, and finally gave up the level playing field, which completely destroyed the Han Dynasty. In fact, Si Mazhao wanted to besiege Jiang Wei. He asked Wargo to contain Jiang Wei and block the back road of Yinping Bridge. At the same time, he also let the species attack Hanzhong area without the main force of Shu army. Jiang Wei guessed that Si Mazhao wanted to unite and besiege himself, so he withdrew from the level tone and did not let himself be besieged.
Yinping road is difficult to walk, the environment in this area is relatively bad, and the road is even more difficult to walk. At that time, no one would believe that anyone would March from Yinping Road, which could not be opened by the army, so Jiang Wei strategically gave up this area. I didn't expect Wei's army to be so brave that it could come along this road. Although many people were injured, this army made great contributions to the attack on the Han Dynasty. What is even more surprising is that Liu Chan, the young master, took the lead in surrendering, making Wei Jun come to Hanzhong unimpeded, and Shu was completely destroyed.
In fact, it is better to say that Jiang Wei forgot these 27 words. It is better to say that Shu was too weak at that time, and his young master didn't resist at all, which even led to the situation of breaking up in discord. Because of this, Shu will perish.
