Zhao Dun was thus recalled to the capital by Xun Lin's father. At the first court meeting after his return, Zhao Dun asked the historian Dong Hu to recount what had happened during his time away from Xinjiang.

Dong Hu unfolded the simple book, read out what happened one by one, and said at the end: "Zhao Dun killed Linggong." After reading it, he raised the bamboo slip in his hand and shook it a few times at the doctors.

Zhao Dun said: "No, no, I didn't do it!" ”

Dong Hu took a step closer and stared at him and said, "As a Zhengqing, you will not cross the border when you flee, and you will not be punished as a thief when you return to China; Who are you if it's not you? ”

Zhao Dun said: "Woohoo! 'My bosom is self-serving! 'That's me!' ”

Dong Hu said: "I only record the facts, and it is someone else's business to judge merit and sin. ”

Confucius later said: "Dong Hu is really a good history in ancient times, and the chronicle does not hide the mistakes of those in power; Zhao Dun was really a good minister in ancient times, and he was wronged but did not use his power to destroy the truth. ”

After the episode, the ministers began to discuss the question of who should be the successor. Jin Xianggong only had one son, Linggong, and Linggong had no son (and it was impossible to inherit the throne), and Gongzi Yong was also killed in the fire, so Zhao Dun proposed to support the exiled Cheng Zhou, the youngest son of Jin Wengong, Gongzi Heibuttocks, as the king, and this proposal was unanimously approved by everyone - because people really couldn't think of any reason to oppose it, unless that person wanted to deliberately oppose Zhao Dun.

Then Zhao Dun ordered Zhao to wear it to Cheng Zhou to meet the black buttocks of the son. Regarding Zhao Dun's approach, Luan Shu later said: "Zhao Xuanzi is really a shrewd person, he made Zhao wear the credit of establishing a new monarch to offset the crime of killing the monarch; He asked Zhao to avoid the eyes and discussions of the Chinese people in case something unexpected happened; Xuanzi also indirectly protected Dong Hu from Zhao Chuan's retaliation. ”

On October 2, the son's black buttocks entered Quwo; The next day, he held a coronation ceremony in the temple of Quwo Wugong, which was for Jin Chenggong.

There is a problem that has plagued the Jin State Office since the late period of the Jin Dynasty.

It turned out that Jin Xiangong eliminated a large number of princes and declared that the office would not be a herd of princes, and later Jin Wengong legalized the exile of the princes, which made the Jin princes withered and weak; So much so that in the end, the power was in the hands of a person with a foreign surname surnamed Zhao. Moreover, due to the decline of the public family, the number of soldiers in the Chinese army is also decreasing year by year, and this situation has had a major adverse impact on the security of the office.

Throughout the Tianxia princes, the power was basically distributed by the princes: the Qi State had Gao, Guo, Cui, Qing, and Dongguo; Lu has three Huan, East Gate, Zang and Zhan; Song Youhua, Le, Huang, Yu, Dang; I won't go into the other countries.

Jin Cheng Gong believed that since the power core of the Jin State still had the name of "Gongfu", it should establish a public family.

In order to solve the contradiction between reality and form, the Jin State Office invented a "Gong Clan System", that is, clans of non-Gong family lineage were simulated as Gong Clans and managed according to the Gong Clan system. The eldest son of the patriarch is called "Yu Zi", and the Yu Zi will inherit the position of the patriarch in the future, and the concubine will serve in the public army.

In this way, the Jin people not only solved the identity problem of non-Gong clans such as Zhao, Shi, and Wei, but also weakened the strength of the major families (because the children of the Gong clan had to serve in the public army).

Zhao Dun's mother was from Chidi, he was born in Baidi, and lived there until he was a teenager; His body and mind are full of Di people's genes.

Di people are simple and simple, heavy on blood and family affection, and rarely use deception. Therefore, when Zhao Dun heard his father for the first time when he was young that the Marquis of Jin was going to exile all his sons or brothers other than the crown prince, he was so surprised that he couldn't keep his mouth shut. He said to his father, "If the prince does not trust his brother, who can he trust?" ”

Zhao Yu replied: "Jin is different from other countries, since the time of Uncle Qu Wohuan, almost all of the monarch's brothers came to the world as enemies. After the death of the prince Shen, Li Ji issued a curse in the Taimiao and said that if the Jin Kingdom raised a group of sons, Sheji would be overturned. As a result, Xiangong expelled almost all the sons.

Later, when Huigong ascended the throne, he was mean and unkind, not only did not recall the princes, but also actively persecuted his brothers who had fled abroad. After Duke Wen ascended the throne, he expelled the sons of Duke Hui. Wen Gong felt that this method was indeed conducive to the stability of the office, so he determined it in an institutional way. Gong Wen believes that foreign surnames and uncles and nephews cannot usurp the throne, so they are more trustworthy than brothers. ”

Zhao Dun continued to ask: "Then should I trust my brothers?" Zhao Yu was speechless and couldn't say a word.

After Duke Wen of Jin ascended the throne, he married one of his princesses, Zhao Ji, to Zhao Yuan. After Zhao Ji got married, she not only asked Zhao Yu to recall Shu Kui and Zhao Dun, but also made Shu Kui his wife and made Zhao Dun his son-in-law.

Zhao Ji later gave birth to three sons, Zhao Tong, Zhao Kuo, and Zhao Yingqi. Zhao Tong, Zhao Kuo and Zhao Dun were at odds with each other, and the two brothers regarded themselves as noble in blood and did not take Zhao Dun in their eyes.

Because Zhao Dun is a person who attaches great importance to family affection, he feels very lost, and then has a huge fear; The question he asked his father when he was young has finally found the answer: it doesn't matter whether Thaksin trusts his brothers or not, what matters is that his brothers don't trust him.

So Zhao Dun took the initiative to give up the position of the patriarch of the Zhao clan, gave it to Zhao Kuo, and said: "Zhao Kuo is the favorite son of the Jun Ji clan. If it weren't for the Jun Ji clan, I would still be a Di person now. ”

Jin Chenggong approved his request, so that Zhao Kuo inherited the Zhao family.

But for the office, Zhao Kuo's position is very embarrassing (because the secretary is in the hands of a non-patriarch); For the family, Zhao Dun's position is very embarrassing (the secretary of state is not the patriarch). Therefore, Zhao Dun simply separated himself from the Zhao family and became his own clan, which the world called "Xuanche Clan".

If it weren't for the fact that Zhao Kuo and Zhao Tong were killed, and Zhao Dun's grandson Zhao Wu changed back to the Zhao family, the Zhao State of the Seven Heroes of the Warring States Period would probably be called the "Yang Che Country".
