People who have seen the legend of Sui and Tang heroes know that Cheng Yaojin was a man of great honesty, first defected to the Wagang Army, then followed Wang Shichong, and then defected to the Tang Dynasty and followed Li Shimin, who was highly skilled in martial arts, was the founding hero of the Tang Dynasty, and as a founding hero, there were many of them, but their final outcomes were unsatisfactory, after Wu Zetian took the throne, in order to smooth his own path, he did not hesitate to execute many of the previous founding heroes, even his own sons, and only Cheng Biting Jin escaped a disaster and was reused.
Cheng Yaojin initially followed Li Mi as his subordinate, after the defeat of Li Mi and Wang Shichong in the battle, he submitted to Wang Shichong and appointed him as a general, giving him extremely high treatment, but Wang Shichong was suspicious of life, and everyone was not accustomed to his style, thinking that his personality was not enough to be a monarch, once in a battle with the Tang army, Cheng Yaojin and others dismounted and said to Wang Shichong: You have always been very good to us, and we also want to be loyal to you, but you are very suspicious, we can no longer follow you, so don't go through it. After that, he defected to the ranks of the Tang Army.
Li Yuan sent Cheng Yaojin to Li Shimin for his use, and Li Shimin had already heard of his heroic deeds and admired him, so he left him by his side, and has been loyal to him ever since, in the Xuanwumen Incident, Cheng Yaojin also participated in it and played a very good role, removing obstacles for Li Shimin, and also received a reward from Li Shimin. But since then, he also knows in his heart that the Tang Dynasty regime is now very chaotic, he has no foundation, he does not want to be too deeply involved in it, he must be appropriately far away, grasp the appropriate degree.
It can be seen that Cheng Yaojin is not as generous as played on TV, he is not only brave in battle but also a wise person, who can recognize and analyze the current situation, but also for himself to leave a way back. Fundamentally, he was an outsider. Therefore, he was more aware of his position, he never favored any side, but he also had a friendly relationship with everyone, and he did not pay much attention to the issue of imperial power, so after Wu Zetian took power later, she had no reason to kill him.
At that time, many ministers such as Chu Suiliang and others were executed by her, exiled, because they all did things against Wu Zetian, so they were liquidated, and Cheng Yaojin did not do anything unfavorable to her, he also kept a certain distance from other ministers in the DPRK, Wu Zetian also knew that if everyone was executed by her, then the government and government were handled normally, after all, the country still had to run, we must leave the old ministers to assist the government, Cheng Yaojin was a good candidate, and the imperial court also had to calm the war at that time. Cheng Yaojin, as a person who has experienced the battlefield, Wu Zetian will definitely reuse him.
Xiao Bian believes that Cheng Yaojin can be able to die well, but he has been reused and he himself is inseparable, he made his position very clear, not greedy for utilitarian profits, did not do anything against Wu Zetian's wishes, and as long as Wu Zetian did not do anything unfavorable to himself, he is still a hero, keeping him can also bring peace to the country, there is use value, then why not reuse it?
