This article is based on Luo Guanzhong's novel Romance of the Three Kingdoms and has nothing to do with the history of zhengshi.
In "Romance of the Three Kingdoms", Lü Bu appeared from the third time to the nineteenth time, and the role was quite a lot. In the winter of the third year of Jian'an, Lü Bubaimenlou died, and his chief strategist Chen Gong died with him.
Reading the "Romance of the Three Kingdoms", people have a general impression of Chen Gong, thinking that he is highly resourceful, but he has not met the Lord, if he protects Liu Bei, then the end will not be so tragic, and even the entire history of the Three Kingdoms may change, but is Chen Gong really so powerful?

Chen Gong's first appearance was in the fourth time, and his identity was Zhongmu County Ling. After Cao Cao failed to assassinate Dong Zhuo, he wanted to flee to his hometown of Yu Commandery (谯郡), passing through Zhongmu County, where he was captured by the guards. Chen Gong, feeling cao cao's loyalty, released Cao Cao and abandoned the officials to go with him, intending to achieve a great cause, but the Chenggao murder incident made Chen Gong see Cao Cao's true face, and he consciously trusted the bandits and abandoned Cao Cao.
Chen Gong's reappearance has reached the tenth time, Cao Cao killed in Xuzhou to avenge his father, Chen Gong came to persuade him, but returned to no avail. Chen Gong's appearances on these two occasions did not show any wisdom and scheming, and it can only be said that as a generation of celebrities, with loyalty and righteousness, worried about the country and the people, his words to Cao Cao were pale and weak, would Cao Cao follow his words? However, Cao Cao's refusal broke Chen Gong's heart, and also completely extinguished Chen Gong's last illusion of Cao Cao, and the Chen Palace after that lived exclusively to eliminate Cao Cao.
In the first year of the Reign of Emperor Xingping of the Han Dynasty, Chen Gong and Zhang Mi invited Lü Bu to enter Yanzhou, and for a time the counties rebelled. At this stage, Chen Gong's strength was fully demonstrated. Under the design of Chen Palace, Cao Cao was in danger many times, repeatedly defeated, Yanzhou's eighty counties only Juancheng, Fan County, Dong'a or Cao Cao's territory, the rest of the counties all supported Chen Gong Lü bu, but it was in the 77:3 situation, Chen Gong and his gang always failed to achieve an overwhelming advantage, and finally cao Cao overturned.
After the unsuccessful battle with Cao Cao for Yanzhou, Chen Gong and others went to Xuzhou to defect to Liu Bei, but took the opportunity to occupy Xuzhou, and the person who made the idea was Chen Gong. After Cao Bao was whipped by Zhang Fei, he wrote a letter to Lü Bu, asking him to take advantage of Liu Bei's trip to Huainan zhang fei to attack Xuzhou when he was drunk, and before Lü Bu could say anything, Chen Gong first said: "Xiao Peiyuan is not a place where he has lived for a long time. Now Xuzhou has an opportunity to take advantage of, and it is too late to regret it if it is lost. You can look at this sentence, the so-called "Xiao Peiyuan is not a place to live for a long time" shows that it has been planned for a long time. How did Chen Gong start learning cao Cao by the love of others?
After Lü Buyuan shot the sword, Yuan Shu sent envoys to make peace with Lü Bu, with the intention of taking Liu Bei's orders, this so-called estranged strategy, Chen Gong had already seen through this plan, he not only did not say broken, but also advised Lü Bu to quickly send his daughter away. What vendetta does Liu Bei have with your Chen Palace, and why should he put people to death? Later, because Zhang Fei snatched Lü Bu's horse, Lü Bu attacked Xiao Pei, and Liu Bei sent an envoy to talk about peace, saying that he was willing to return the horses as many as possible, and only wished that the two families would boycott the troops, Lü Bu wanted to obey, or Chen Gong provoked from it: "If you don't kill Liu Bei now, you will be harmed in the long future." "It's true that Lü Bu was indeed harmed by Liu Bei in the end, but it was you who harmed him first, which led him to harm you, not that people wanted to harm you at the beginning." This is like saying that Zhang San first determined that Li Si wanted to kill him, so he decided to strike first, Li Si was forced to fight back in self-defense, and finally killed Zhang San, Zhang San still thought he had a plan before he died, is this not delusional?
Speaking of Chen Jue Chen Deng's father and son, these two are the indigenous heroes of Xuzhou, Chen Gong does not have a good relationship with them, but is more jealous, and wants to kill them at every turn, you can see that they are "unpredictable in their hearts, it is advisable to be good at prevention", why did they finally fall against their plans?
Chen Gong's last appearance was in the nineteenth time, Lü Bu did not accept Chen Gong's plan, and finally the White Gate Tower was tied up, and Chen Gong could not escape and was also captured. People often have a subjective opinion about the choice, believing that when there are two choices, the one that is not chosen is better than the one chosen, and the same is true for Lü Bu's choice. During the siege of Pi by Cao Cao's soldiers, Chen Gong proposed at least three strategies, but Lü Bu did not listen to one, and finally the soldiers were defeated and killed, so was it not lü Bu who listened to Chen Gong's plan to turn defeat into victory? I'm afraid not.
Looking at Chen Gong from appearance to the end, one has no brilliant strategy, the other does not have a grand plan, but likes to calculate others, calculating, while enjoying the pleasure of manipulating Lü Bu alone, while doing whatever it takes to retaliate against Cao Cao, his intelligence level can be regarded as medium, and his life is too rigid, before his death, Cao Cao asked him: "You think you are resourceful, how did you get to this point today?" Chen Gong replied, "Hate Lü Bu for not following my words!" "Lü Bu didn't follow your words for a reason, do you know?"
