Zheng Zhuanggong's father is Zheng Wugong, and his mother is a military commander and the daughter of Shen Hou. In the fourteenth year (757 BC), Wu was born, and in the seventeenth year (754 BC), a young uncle was born. Because Mao was born in dystocia (he was born in Wujiang's sleep and didn't know until he woke up), his style was frightened, so his style disliked him and spoiled his younger brother Duan Shu. In 744 BC, Wu Gong was seriously ill. In front of Wu Gong, Wujiang said to Duan Xianshu, "I want to be a prince and a husband." In the twelfth year of Historical Records of Zheng Ji, Wu Gong died of illness and Yu Sheng succeeded to the throne. This is Zheng Zhuanggong. In the first year of Zhuang (743 BC), Wujiang requested the land (now Sishui Town, Xingyang City, Zhengzhou City) as an uncle's fief. Zhuang Gong said, "There is no way, because the terrain in the city is dangerous and it is a military location related to national security." The military commander changed the tyrant Zhuang Gong to seal Beijing (now southeast of Xingyang, Zhengzhou City) as the Shu land. Beijing is the city of Zheng, with high walls, large population and rich products. Zhuanggong refused in his heart, but because of his mother's request, he had to agree. The doctor advised Jin Zhong, "Beijing is bigger than the capital, so it can't be used as my brother's fief." Zhuang Gongzheng: "This is the request of Jiang Mu's family. I can't help but listen! " After Duan Shu arrived in Jingyi, he was called Uncle Jing. With the support of his mother Chiang Kai-shek, he never cared about respecting the monarch and governing the people. Knowing that his mother was extremely unhappy about his succession, he also knew who he was and Duan Shu's plan to seize power, but his face did not change color. Duan Shu's abnormal behavior in the capital caused people's discussion. The doctor Jizhong said to Zhuang Gong, "All the capital cities are surrounded by walls of more than 300 feet, which is the scourge of the country. Therefore, according to the former king's system, fiefs should not exceed one-third of the state capital, one-fifth of the medium-sized ones and one-ninth of the small ones. Now that the capital is illegal, how can you tolerate it? " The landlord said helplessly, "Jiang Jia wants it, how to prevent harm?" It means that if Chiang Kai-shek wants to do this, where can I avoid this disaster? Ji Zhongdao: "When will the Jiang family be satisfied? It is better to find a place for Uncle Duan as soon as possible to prevent him from developing and spreading. Once it spreads, it's difficult to deal with. The spreading weeds are still hard to get rid of, not to mention your beloved brother? " Duke Zhuang said, "If you do more injustice, you will die. Let us wait and see. "

Zhuanggong gave in again and again, prompting Uncle Duan's ambition to increase day by day. Soon Duan Shu ordered the western and northern borders to obey himself at the same time. Then he brought two small towns near Jingyi into his jurisdiction. Lu, the son of the doctor, said to Zhuang Gong, "One country cannot have two monarchs. What will your king do? If you want to give up your throne to your uncle, I will serve him; If not, please get rid of him and don't let the people have second thoughts. " Zhuang Gong said tepidly, "There is no need to get rid of him. Without justice, it is impossible to win the hearts and minds of the people. He will be in trouble sooner or later. "

Duan Shu repeatedly challenged the authority of Zhuang Gong and endured again and again. Does he really believe that God will punish Uncle Duan instead of doing it himself? That's not true. This is because Zheng Zhuanggong, as a king of a country, can't put his feelings on his face. More importantly, Zhuanggong knew that if he started work too early, he would be talked about by outsiders, saying that he was unfilial and unjust, so he deliberately let Duan Shu's plot continue to be exposed.

Granduncle managed the city in Beijing, hoarding food and grass, training, stepping up the expansion of power, and conspired with his mother Wujiang to prepare to attack Zheng's usurpation of power. Knowing the date of their rebellion, they sent two hundred chariots to attack the capital. The people of the capital opposed Duan and fled to Yan. Duke Zhuang once again marched into the state of Yan and continued his crusade. On May 23rd, Luyin, my uncle fled to * * *. The rebellion subsided.
