In the first year of Qinglong (233), Cao Gon was reduced to the fiefdom of the two counties for violating the ban on Kyoto. In the second year of Qinglong (234), the two counties were restored. In the third year of Qinglong (235), Cao Gon died of illness, and was called King Gong, and his son Cao Fu was the lord.

Cao Gon was studious when he was young, and he was able to write articles as a teenager. Every time he reads, his subordinates often fear that he will get sick due to energy damage, and he is repeatedly discouraged, but he likes to read and cannot be stopped. After the feudal lord, he advocated frugality and urged his wife and concubine to spin and weave yarn to become a daily affair for his family.

Cao Gon has written articles with a total of more than 20,000 words, and although his talent is not as good as that of his brother Chen Siwang Cao Zhi, he has the same hobby as him.

Cao Gon was fond of learning as a teenager and could write articles as a teenager. Every time he reads, the literary officer and the attendants often fear that he will get sick because of the damage to his energy, and repeatedly persuade him to stop, but he likes to read and cannot stop. In the twenty-first year of Jian'an (216), Cao Gon was awarded the title of Pingxiang Marquis.

In the twenty-second year of Jian'an (217), he was renamed the Marquis of Dongxiang, and in the same year, he was renamed the Marquis of Zan. In the second year of the early Huang dynasty (221), he was knighted as the Duke of Zan, and the officials and subordinates congratulated him, and Cao Gon said: "I grew up in the deep palace, and I did not know the difficulty of harvesting crops, and there were many mistakes of arrogance and pleasure. The sages have celebrated my joys and should help me to mend my shortcomings. ”

Every time Cao Gon's brothers played and entertained, he pondered the classics alone. The literary officials and the defense assistants (the names of the officials of Wei during the Three Kingdoms, set up in the feudal states of the kings, to supervise the actions of the kings) consulted with each other and said: "We accept the edict to inspect the behavior of the Duke of Zan, and if there is a mistake, we should report it, and if there is a good thing, we should also report it, and we cannot hide his goodness!" So they praised and stated the beauty of Cao Gon together. When Cao Gon found out, he was extremely frightened and rebuked the literary officer, saying: "Improving one's self-cultivation and adhering to chastity is just the behavior of ordinary people, but you have reported it to the above, and this is precisely an increase in the burden and drag on me. And if there are good words and good deeds, why worry about others not knowing, but rush to do it together, it will not do me any good. "Cao Gon's vigilance has always been so cautious.

On the first day of the third month of the third year of the Huang dynasty (222), Cao Gon was named the king of the North Sea. In the fourth year of the early Huang dynasty (223), he was renamed King Zan. In the seventh year of the early Huang dynasty (226), he was renamed the king of Puyang.

Cao Gon advocated frugality and frugality, urging his wives and concubines to spin and weave to form a habit and become a daily affair for his family. In the winter of the fifth year of Taihe (231), Cao Gon returned to Beijing to meet Emperor Cao Rong of Wei Ming. In the sixth year of Taihe (232), he was renamed King of Zhongshan.

When Cao Gon came to see Emperor Wei Ming, he violated the ban in Kyoto. In the first year of Qinglong (233), the official in charge criticized Cao Gon. Emperor Wei Ming issued an edict saying: "The King of Zhongshan has always been respectful and cautious, and when he came here by chance, it is better to judge this matter by the rules for evaluating the emperor's relatives." The officials in charge were stubborn, and Emperor Cao Rui of Wei Ming had no choice but to issue an edict to reduce the fiefdom of Cao Gon's two counties and 750 households. Cao Gon was worried and frightened, and warned his subordinate officials to be more cautious. Emperor Wei Ming appreciated Cao Gon's intentions, and in the second year of Qinglong (234), he restored the fiefdoms of the two counties he had previously reduced.

In the autumn of the third year of Qinglong (235), Cao Gon fell ill, and Emperor Wei Ming issued an edict to send a physician to see him. Cao Gon was very ill and ordered his subordinates, saying, "I lack virtue and I am ashamed of the favor of the Son of Heaven, and now my life is coming to an end." I like frugality, but the imperial court has a system of dying reports as a code to be followed throughout the country. When I was angry, I must follow the orders of the edict from the time I park the coffin to the time I am buried. In the past, when I saw his grave, I often thought of his legacy and hoped to rely on the soul of the sage to rest underground and build the boundary of my grave, and I must go there and choose to be near it. The "Rites" stipulate that a man shall not die at the hands of a woman. Hurry up and build the East Hall on time. ”

After the East Hall was built, Cao Gon named it "Suizhi Hall" and hurried to live there in a car. He also ordered his son Cao Fu, who inherited the throne, and said: "You are still too young, you have not received a family education, and you have become a prince so early, you only know happiness, but you don't know suffering, and you will definitely have the fault of pride and luxury." When receiving ministers, be sure to follow etiquette. Even if you are not a minister, you should give thanks to the elderly. Serve your brother with respect, and be considerate of your brother. If a brother has bad deeds, he should kneel down and admonish them, and if he does not obey the advice, he will reason with tears. If the reasoning still does not change, then tell their mother. If you still don't change, you should tell the Son of Heaven to know and resign from the fief together. Rather than suffer calamity by keeping grace, it is better to live in poverty to protect yourself. This is only talking about the great sins, and the small sins should be covered up for them. You little child, cultivate yourself carefully, serve the holy pilgrimage with loyalty and steadfastness, and serve the concubine with filial piety. at home at the orders of the concubine; Receive a lesson from King Pei outside. Don't slack off on your mind as a way to comfort my soul. ”
