Liu Bei hoped that Zhuge Liang could assist Liu Chan in governing the affairs of the Shu state, and Zhuge Liang was ordered to do his best naturally. However, Liu Bei's son Liu Chan was notoriously mud-ridden and could not support the wall, not only was he lazy and lazy, but he was also faint and incompetent, and the Shu kingdom was all supported by Zhuge Liang, the chancellor. In the late Shu Han Dynasty, the talent withered away, coupled with the inaction of the monarch Liu Chan.
Even if Zhuge Liang had the wisdom of heaven, it would not help after all. What's more, Liu Chan also listened to rumors and fortified Zhuge Liang everywhere, which further increased Zhuge Liang's burden. Later, Zhuge Liang launched several Northern Expeditions, just to fight, but all failed. Zhuge Liang was also tired because of this, and eventually fell ill and died in Wuzhangyuan. After Zhuge Liang's death, Shu Han was even more scattered.
His son Zhuge Zhan succeeded his father and continued to guard the Shu Han. But at this time, Shu Han had reached the stage where the lights were exhausted, and he could not be saved by anyone. Cao Wei's Deng Ai attacked the Shu state, and at this time the Shu state was unable to resist, even if Deng Ai only had 2,000 soldiers and horses, Liu Chan had to obediently surrender. At this point, the Shu Han dynasty was destroyed, and the Jiangshan that Liu Bei had worked so hard to fight was thus broken in the hands of Liu Chan.
After Deng Ai accepted Liu Chan's surrender, he found an object in Liu Chan's room and knew why there were people like Zhuge Liang sitting in the town, and Shu Han still could not escape the fate of destruction. At that time, Deng Ai found the Shu Han's shimin book, and through the above data, he learned that there were more than 900,000 people in the Shu Han, but the officials and soldiers added up to more than 100,000.
It should be known that in ancient times, the foundation of a country's prosperity lies in agriculture, but the Shu Han labor force at this time was pulled to serve as a soldier, which shows the lack of manpower in the Shu Han. The old, weak, sick and disabled who stayed at home were not taken care of, there was no fresh blood injected into society, and gradually, Shu Han had to go to extinction. Therefore, no matter how powerful Zhuge Liang was, he could not save the terminally ill Shu Han.
