In order to sit on the throne of Wu Zetian, by hook or by crook, why let Cheng go?

Speaking of Wu Zetian, everyone must be familiar with it, right? ! Wu Zetian is the only universally recognized and well-known female emperor in the history of China. During the reign of Wu Zetian, the policy was steady, the soldiers were just right, the culture was revived, and the people were rich. So there was the praise of "Zhenguan Legacy". It can be said that Wu Zetian made great contributions to history, but Wu Zetian also had many negative comments. But in order to sit on the throne, Wu Zetian did kill all the founding heroes by hook or by crook, but strangely, why didn't she move?

You must be familiar with the departure, right?

Cheng was the founding general of the Tang Dynasty. He was brave and good at fighting. But I have to say. Wu Zetian's road to the throne was bumpy. After all, this is a woman who wants to monopolize power. In the feudal dynasty, it was really a joke. The minister of the DPRK naturally raised objections, but all those who stopped her were executed by Wu Zetian. You know, whoever dares to stop Wu Zetian from becoming emperor will certainly come to no good end. Even the founding heroes of the dynasty were killed. Although many people have opinions on her practice, they still dare not oppose Wu Zetian. But among these people, why didn't they move?

You know, Cheng was saved from death because of his own stupidity. There are several reasons. First, Cheng did not engage in cronyism. At that time, Cheng was 60 years old. His cleverness lies in that he doesn't let his family communicate with people in the imperial court and leads a simple life, so he poses no threat to Wu Zetian. Second, Cheng knows how to preserve our sanity, and he is indifferent to this kind of intrigue and infighting. For Wu Zetian to ascend to the throne, the court ministers made choices, but Cheng just didn't know about it, that is, he acquiesced in Wu Zetian's affairs.

So Wu Zetian had no reason to kill him, did she? Third, Cheng is a founding hero and a veteran of the Three Dynasties. Wu Zetian also kept him for the benefit!
