Zhao Dun, Zhao Wu's grandfather, was the Minister of Jin Dynasty who was in a position to be in power. He was not good with tu'an Jia. Tu'an Jia set up a soldier to kill Zhao Dun's family. For a while, Zhao family became a blood stream. As a sister of Jin Chenggong, Zhao Wu's mother was still in the palace of Zhaowu, but she could not escape the fate of death. Zhao Ji told her children that if you want to make Zhao family extinct, you cry if you want to kill Zhao family Don't cry if you don't let Zhao go extinct. Unexpectedly, Zhao Wu of the baby didn't make any sound and escaped a robbery. At that time, the cost of avoiding the disaster was very high. Gongsunzhujiu gave his life, while Cheng infant gave his own children. When Zhao Wu was an adult, Jin Jinggong wanted to remove tu'anja, the official of power, so he had the same enemy with Zhaowu. He hid Zhao Wu in the palace and chose the opportunity to kill the Tuan Jia. Finally, Zhao Wu avenged him. However, he was too lonely to raise his Cheng infant and killed himself. He had no family members. In politics, I have never got the ambition. I was able to sit in Zhengqing's throne until five years before I died. Although he successfully presided over the military alliance in the spring and Autumn period, it established the situation of Jin Chu sub hegemony, but his political ambition did not really realize. In depression, he went through a lonely life.
Fortunately, his descendants are very competitive. Zhaojingzi, the son of Zhaowu, is also a Zhengqing in history. Zhaojianzi, grandson, is outstanding in his political achievements and has started various reforms on his own land. It can be said that Zhao Jianzi's reform measures are very effective. Zhao Jianzi, as the family of Shiqing, has the most effective reform measures in all the six top officials who have carried out the reform.
Zhao Wu's descendants also became a generation of tyrants in the late spring and Autumn period, and later, they were divided into Jin states with Han and Wei. In 403 BC, Zhao Wu was recognized by the royal family of Zhou Dynasty as the state of the time.
