To tell a joke Zhuge Liang is not trusted, if he is not trusted, will Liu Bei be alone?
This is the imperial power technique, no one can use Zhuge Liang to prevent him from seizing power. Entering Sichuan only brought Pang Tong but not Zhuge Liang, and the decisive battle in Hanzhong only used the Fa Zheng and did not use Zhuge Liang, only let Zhuge Liang manage the grain and grass. In the battle of Yiling, Zhuge Liang was not even brought, and his subordinates led their divisions to the expedition without being powerful, which shows that Liu Bei did not trust Zhuge Liang. Later, there was really no way, the army was almost exhausted, and Shu Han couldn't hold it without Zhuge Liang, so he had to use it.
Cao Rui also guarded against Sima Yi, and appointed him as the minister of Tuogu, reusing it to appease while guarding against it. Sima Yi and Zhuge Liang are in the same situation in the emperor's heart, these two people are wise and demons, and they can't see their loyalty and treachery in their hearts.
The power and ability are too great, and if he doesn't kill, he has to reuse and appease him, and at the same time arrange someone to guard against him. The emperor has always been on guard against the ministers, and Zhuge Liang belongs to the side of the ministers. If Zhuge Liang is a careerist like Sima Yi, if the Northern Expedition is successful, you can abolish the lord and stand on your own, if you are an emperor or a business owner, and you have a person with outstanding ability, great power, and too high prestige, you will also guard against him taking away your country or company.
Cao Pi's way of supporting orphans is not good, he underestimated Sima Yi's ability, overestimated Cao Zhen's ability and Cao Xiu's ability, and felt that Er Cao could suppress Sima Yi. Sima Yi is more intelligent than demons, how Er Cao is his opponent, and finally led to Sima Yi seizing power and destroying Wei. If I were Cao Pi, I should be ruthless and slaughter Sima Yi and get rid of future troubles forever. Cultivate more talents to guard against Wu Shu, and employ people not only to use one person, but also to cultivate powerful ministers who are difficult to control.
The defense of Shu Han is guarded, as long as the grain and grass in the city are increased and strengthened, the grain and grass of Shu Han will be cut off, and the grain and grass of Shu Han will be retreated, and the grain and grass are the dead hole of Shu Han. Focusing on the attack on Soochow, training strong sailors, taking action step by step, slowly devouring Soochow. As soon as Eastern Wu is destroyed, Shu Han will also perish without foreign aid. It would be better to appease Eastern Wu, give Eastern Wu benefits and promise heavy benefits, and let it be neutral or ally with Cao Wei, so as to avoid fighting on two fronts and concentrate the main force to deal with it.
During the Three Kingdoms, the combined population of Wu and Shu did not have much grain and grass strength as Cao Wei, and Cao Wei occupied the Central Plains, and there were many generals and a lot of grain and grass, and he could cope with it even if he fought on two fronts. The defeat of Shu Han through Yiling had less than 100,000 troops and a population of only one million. It is enough to guard against the 200,000 army of Shu Han, and the battle of Yiling of Eastern Wu also suffered heavy losses, and the population is about the same as that of Shu Han, and it is also advisable for 200,000 troops to slowly devour Eastern Wu. A two-front battle of 400,000 troops is sufficient, and only the commander is lacking.
However, the way of the ministers also depends on whether their abilities are equal, if one person's ability is better than the other people, find an opportunity to kill the others, and they can abolish the emperor and stand on their own by themselves. Emperor Wu of the Han Dynasty also entrusted Gu Huo Guang and several other ministers to assist the young lord, Huo Guang found an opportunity to destroy several other ministers, and had the right to abolish the emperor. Liu He, the Marquis of Haidu, was disobedient and disrespectful, and was ousted from the throne, and made Liu Yi the emperor.
Emperor Xuan of the Han Dynasty could endure and obey Huo Guang, and when Huo Guang died, he punished the Huo family. Emperor Shunzhi asked Gu Ao to worship Sonny and other four ministers to assist Kangxi, and Ao Bai tried to get rid of several people who monopolized power and humiliated the emperor. Fortunately, Kangxi was able to pretend not to do political affairs and love wrestling, and let a group of wrestling people worship before officially taking power. History
