Why did Cheng win the trust of Emperor Taizong?

? Because Emperor Taizong knew that Cheng would not rebel against him, he was particularly at ease. In addition, Cheng has no education and no ability to rebel, and Cheng followed before the founding of the People's Republic of China. Is one of Li Shimin's old men, so he is listed as one of the 24 heroes of the pinnacle. Cheng can win the trust of Emperor Taizong, which is rare in history, because Cheng has recognized three masters including him before and after. In history, such people are despised, let alone reused, just like Lu Bu has always been called by others? Slave's third surname? However, Cheng can be reused by every master, while Shi Biao, Wang and Wang all think that Cheng is uneducated and easy to control, and Cheng's own force value is high, so it is necessary to reuse such a good knife around anyone like this.

In addition, Cheng also participated in the Xuanwu Gate incident and was the core figure of the Xuanwu Gate incident. Without Cheng, the Xuanwu Gate incident would not have been so easy and successful. Therefore, his accession to the throne was made by himself, and he has always been blessed by Cheng. Maybe he still thinks that Cheng will bring him good luck. To sum up, if a courtier wants to live and work under the emperor for a long time, he doesn't need too much credit or wisdom. This will make the monarch doubt you soon. This kind of thing will happen again and again in history, but few people will notice it. Therefore, when the People's Republic of China was founded, there was always a case that the founding emperor slaughtered the founding minister. Cheng did not know if he was really confused, but he did survive the crisis again and again. ?
