? There is no absolute right or wrong in troubled times. Liu Bei, in the name of Han clan, has no military power. He can only speak the so-called justice, and those who have the strength to unify the world should be orthodox. What is most needed in troubled times is stability. Whoever can make the world settle down is right. When Chen Gong followed Cao Cao, he valued Cao Cao's ambition. He also saw from the killing of Lv Boshe that Cao Cao would not trust anyone, and he was the only one who could trust him. So Cao Cao can't do anything. Chen Gong also had the ambition of dominating the world, but he didn't like Cao Cao's distrust of anyone, so he left him.
? Chen Gong knew that Liu Bei was a hypocrite, which was not enough to ask for anything. Since he took the title of Uncle Han, he realized that Liu Bei's early state was really unsatisfactory, which was simply a disaster. No matter who takes refuge, he will lead the disaster to that person's territory. I won't comment on whether Liu Bei is a hypocrite for the time being, but judging from Chen Gong's performance, he decided that Liu Bei was a hypocrite and was at a loss. It's a pity that he was wrong about someone. After Liu Bei got Zhuge Liang, he shined brilliantly, and the battle of Chibi directly established his position as a tripartite confrontation among the three countries.
Another possibility is that Chen Gong knew that he could not control Liu Bei. As mentioned above, Chen Gong needs an obedient and powerful vassal, and Liu Bei is obviously not. Liu Bei alone could not enter Chen Gong's eyes. At that time, Liu Bei was not wise, at least Chen Gong thought so.
? Lu Bu was a powerful warlord in the late Eastern Han Dynasty. First of all, Lu Bu used excessive force, but most people couldn't beat Lu Bu. Only Liu, a former Hulao Pass official, was tied. Note that this is still the case that Lu Bu underestimates his enemy. Unfortunately, it is difficult to find the shadow of Lu Bu's single-handedly killing the stars in the official history. Therefore, Lu Bu became the only record that Lu Bu could boast of in the three British wars. Although Lu Bu is brave, his political mind is particularly simple, which naturally includes (strategic mind). When Lu Bu was depressed, it was Chen Gong who stood up and helped Lu Bu regain his confidence. At this time, Lu Bu obeyed Chen Gong. Chen Gong was not the only counselor in Lu Bu's army, but Chen Gong was definitely the head of the counselor group.
Once Cao Cao went out to fight, Lu Bu listened to Chen Gong's plan and attacked Yanzhou, which made him unable to take care of himself at the first time. If Cao Cao's army did not return in time, it is still unknown whether Cao Cao can become a lean man. You know, Lu Bu's fighting capacity is very strong, and most of them are led by Xiliang fighters.
West cool military forces is the division of steel, and simple-minded Lyu3 bu4, nature is the best choice for Chen Gong. There is no other choice. Yuan Shao and Yuan Shu will never have a crush on Chen Gong, and Cao has a crush on him, but Chen Gong still doesn't like his treachery. Tao Qian and Liu Biao are good at self-control. Chen Gong didn't choose Liu Bei because he didn't deserve Chen Gong's teaching, while Lu Bu was simple-minded and only used by Chen Gong.
