Chen Gong was a general under Cao Cao stationed in Dong Commandery who, in the 1st year of Xingping (194), while Cao Cao was away attacking Tao Qian, persuaded Zhang Miao to welcome Lü Bu and make him Governor of Yan Province. After that he fought Cao Cao at Lü Bu's side. Records, Wei 7 §12–13Records, Wei 1 §33
When they were besieged at Xiapi in the 3rd year of Jian'an (198), he talked Lü Bu out of surrendering, but at the end of a three-month siege he was bound by Lü Bu's generals and handed over to Cao Cao, and he died together with Lü Bu. Records, Wei 7 §25–27Records, Wei 1 §49
Chen Shou's main text gives neither his courtesy name nor his place of origin; there is only a short passage attached to the end of Lü Bu's record in the Biographies of Lü Bu, Zhang Miao and Zang Hong in Records of Wei 7, and the assessment does not treat him separately. In the Romance he first appears in Chapter 4 as the magistrate of Zhongmou County, where his courtesy name is given as Gongtai; he appears in 12 of its 120 chapters (Chapters 4–19), and his name is in no chapter title. He releases Cao Cao and goes with him, then abandons him, and later, as Lü Bu's adviser, repeatedly offers stratagems that go unused.

In the 1st year of Xingping (194), when Cao Cao again went out to attack Tao Qian, Zhang Miao's younger brother Zhang Chao plotted to rebel against Cao Cao together with Cao Cao's general Chen Gong and the Attendant Officers of the Household (congshi zhonglang) Xu Si and Wang Kai. Chen Gong said to Zhang Miao that at a time when heroes were rising together and the realm was falling apart, it was surely contemptible for him, with the multitudes of a thousand li at his command, to be controlled by another. He went on to urge that, since the province's army had gone east and left the place empty, they should for the time being welcome Lü Bu, a fine fighter whom no one could stand against, govern Yan Province together with him, and wait for the times to change. Zhang Miao followed his advice. Records, Wei 7 §12–13
Cao Cao had originally had Chen Gong lead troops and remain garrisoned in Dong Commandery, but Chen Gong took those troops east, welcomed Lü Bu, made him Governor of Yan Province and seized Puyang. The commanderies and counties all responded, and only Juancheng, Dong'e and Fan held out for Cao Cao. The Biography of Xun Yu records that many of the commanders and senior officials left on guard had plotted in secret with Zhang Miao and Chen Gong, and that the troops settled down only after Xiahou Dun, Administrator of Dong Commandery, hurried there and that night executed several dozen men who had plotted rebellion. Records, Wei 7 §13Records, Wei 10 §5–6
According to the Biography of Cheng Yu, a man who had come over from Lü Bu's side reported that Chen Gong meant to lead troops himself to take Dong'e and to send Fan Yi to take Fan, and officials and people alike were afraid. Persuading Jin Yun, the magistrate of Fan, Cheng Yu said that 'Chen Gong and the others have merely come together for the moment as circumstances dictate, and will not be able to serve one another as lord.' Jin Yun stabbed Fan Yi to death, and when Cheng Yu sent a separate cavalry force to cut off Cangting Ford, Chen Gong arrived but could not cross. Records, Wei 14 §8 · 10–11
Cao Cao returned and faced Lü Bu at Puyang for more than a hundred days, and in the summer of the 2nd year of Xingping (195) he attacked and beheaded Lü Bu's generals Xue Lan and Li Feng, who were stationed at Juye. Lü Bu came again from Dongmin with Chen Gong and more than 10,000 men to fight, but Cao Cao, whose troops were few, laid an ambush, sent out a surprise force and routed them. Around this time Xun Yu told Cao Cao that, now that Li Feng and Xue Lan had been crushed, if he divided his forces and attacked Chen Gong in the east, Chen Gong would not dare look west, and urged him to subdue Lü Bu first. Records, Wei 7 §14Records, Wei 1 §33Records, Wei 10 §8–10
In the 3rd year of Jian'an (198), when Lü Bu again sided with Yuan Shu, Cao Cao set out on campaign in person and arrived beneath the walls of Xiapi. Cao Cao sent a letter setting out where fortune and misfortune lay, and Lü Bu wanted to surrender, but Chen Gong and the others, believing their own guilt to be deep, blocked the plan. The Annals of Emperor Wu records that Chen Gong and the others sought help from Yuan Shu and urged Lü Bu to go out and fight, but that when he fought and was defeated again, he went back and held fast. Records, Wei 7 §25Records, Wei 1 §48
As the fighting dragged on and the soldiers grew weary, Cao Cao wanted to turn back. Xun You and Guo Jia said that 'Lü Bu is brave but has no strategy, and Chen Gong has wisdom but is slow,' and urged an immediate assault now, while Lü Bu's spirit had not recovered and Chen Gong's plans were not yet settled. Cao Cao breached the Yi and Si rivers to flood the city. At the end of a three-month siege, when high and low had become divided in heart, Lü Bu's generals Hou Cheng, Song Xian and Wei Xu bound Chen Gong and surrendered with their troops. Records, Wei 10 §57Records, Wei 7 §26Records, Wei 1 §49
Cao Cao asked the captured Chen Gong whether he did not wish his old mother and his daughter to live. Chen Gong replied that he had heard that one who governs the realm by filial piety does not cut off another man's parents, and one who spreads benevolence across the four seas does not cut off another man's ancestral sacrifices, and that the matter of his old mother rested with Cao Cao, not with himself. Cao Cao summoned his mother and supported her until her death, and married off his daughter. Records, Wei 7 §29
Chen Gong died together with Lü Bu. Lü Bu was strangled, and Lü Bu, Chen Gong, Gao Shun and the others all had their heads cut off and sent to Xu, where they were displayed before being buried. Records, Wei 7 §27Records, Wei 1 §49
In the assessment of Records of Wei 7, Chen Shou said that Lü Bu had the courage of a roaring tiger but lacked brilliant strategy, was fickle and looked only to profit, and wrote that even Taizu of Wei had been blinded by Zhang Miao. He expressed regret for Chen Deng and Zang Hong, but said nothing separately about Chen Gong. Records, Wei 7 §62
In Chapter 4 of the Romance, when Cao Cao, fleeing after his attempt to stab Dong Zhuo, is caught at Zhongmou County, the magistrate says he recognized him when he was seeking office in Luoyang and has him locked up. At night, after hearing Cao Cao's intentions, he unties his bonds with his own hands and bows to him as 'a truly loyal and righteous man of the realm', reveals that his surname is Chen, his given name Gong and his courtesy name Gongtai, and that his old mother, wife and children are in Dong Commandery, and then gives up his office and follows Cao Cao. Romance, Ch. 4 §34–37
At the house of Lü Boshe in Chenggao, hearing the sound of knives being sharpened, he and Cao Cao kill eight members of the household, only to find that what was to be slaughtered was a pig. When Cao Cao then cuts down even Lü Boshe, who is on his way back after buying wine, Chen Gong says that 'to kill knowingly and deliberately is a great unrighteousness', and Cao Cao answers, 'Better that I wrong all the people of the realm than let the people of the realm wrong me.' That night Chen Gong is about to kill the sleeping Cao Cao, but, judging it unrighteous to kill a man he had followed for the sake of the state, he puts his sword back, and at the start of Chapter 5 he leaves alone for Dong Commandery. Romance, Ch. 4 §38–44Romance, Ch. 5 §1
In Chapter 10, as an Attendant Officer of Dong Commandery on close terms with Tao Qian, he goes to Cao Cao to dissuade him from massacring the people of Xu Province but is refused, and he takes refuge with Zhang Miao, Administrator of Chenliu. In Chapter 11 he urges Zhang Miao to take Yan Province together with Lü Bu while Cao Cao has gone east on campaign and left it empty. In Chapter 12 he devises a plan to have Tian, a wealthy man of Puyang, send a false letter offering to act as an inside ally, lure Cao Cao into the city and set fire to its four gates, and Liu Ye on Cao Cao's side warns that 'Lü Bu has no strategy, but Chen Gong has many schemes.' Romance, Ch. 10 §34–36Romance, Ch. 11 §35–36Romance, Ch. 12 §2–4
He also offers stratagems during the Xu Province years. In Chapter 14 he urges seizing Xu Province while Zhang Fei is drunk; in Chapter 16 he has the marriage alliance with Yuan Shu hurried along so that the daughter is sent to Shouchun, and says that if Liu Bei is not killed now, harm will come of it later. In Chapter 18, rebuked by Lü Bu after telling him to beware of Chen Gui and his son, he sighs that 'loyal counsel is not accepted, and we will surely meet with disaster,' and on a hunting trip he catches a messenger carrying Liu Bei's secret letter to Cao Cao. Romance, Ch. 14 §56Romance, Ch. 16 §24–26 · 35Romance, Ch. 18 §20–22
At Xiapi in Chapter 19, Chen Gong proposes attacking Cao Cao's army before it can set up its camps, and from the city wall he denounces Cao Cao as a traitor and hits his parasol with an arrow. Lü Bu approves both his plan to station troops outside the city so that the two forces support each other like the horns and legs of a deer and his plan to cut Cao Cao's supply route, but gives them up when his wife Lady Yan tearfully stops him and Diaochan too tells him not to go out in person, and Chen Gong sighs, 'We shall die without even a place to be buried.' When the city falls, Chen Gong flees through the south gate and is captured by Xu Huang. Romance, Ch. 19 §25–31 · 51
At the Baimen Tower, when Cao Cao says, 'Gongtai, have you been well since we parted?', Chen Gong answers, 'Your heart is not upright, and that is why I abandoned you,' adding that Lü Bu has no strategy but is not as treacherous as he is. He laments that Lü Bu did not follow his advice, says that the life or death of his old mother, wife and children rests with the illustrious lord, asks to be put to death at once, and walks down from the tower of his own accord. Cao Cao weeps as he sees him off, sends his family to Xudu to be cared for the rest of their lives, and has his body placed in an inner and outer coffin and buried at Xudu. Romance, Ch. 19 §53–56
