Wu Zetian was the only female emperor in history, she relied on her excellent political talent, successfully seized the Li Tang dynasty, but because she was the only woman as emperor, so her regime was not stable at first.

The Li Tang dynasty had been developing for such a long time, and had a certain strength, and there were still many feudal lords underneath, which made the Empress Wu face great pressure, and there were indeed many people inside and outside the dynasty who opposed her claim to be the emperor.

In order to be able to solve these threats to their own people, the Empress Wu chose to vigorously promote the cool officials, using these people to punish those who oppose their own, her reign, killed many princes and nobles, the ministers of the dynasty also died a lot.

One of them, Pei Yan's death, for the political situation of the impact is relatively large, Pei Yan comes from a famous family, and later also got the high Zong's reuse, because of his erudition, so in the death of the high Zong, specifically to let him come to assist the crown prince.

But did not expect, Pei Yan hope to grasp the power, he and Li Xian had a conflict, so he chose to cooperate with the Empress Wu, teamed up to abolish Li Xian, this incident let Pei Yan get the Empress Wu's trust.

Later, he was still subjected to the suspicion of Empress Wu, after Xu Jingye rose up, Pei Yan was involved, and eventually was killed by the emperor, his death, so that the dynasty lost the person who could restrain the Empress Wu, which also let Wu Zetian in the back to be able to successfully claim the title of emperor

Regarding the death of Pei Yan, in fact, there are also a lot of controversy, there is one thing that is very famous, at first, Pei Yan wrote "The letter was sent to Xu Jingye, but he didn't expect to get it by the emperor, after Wu Zetian saw the letter, she chose to kill him.

And the civil and military officials do not understand the content of this letter, as for the green goose in the end what is the meaning of, there are not many people can guess, then why Wu Zetian just rely on these two words alone, Pei Yan was killed?

In fact, these two words are utilized to decipher the word splitting method, 'green' word can be split into 'December', 'goose' word split into 'I am with myself', together, Pei Yan intends to cooperate with Xu Jingye's army to rise up in the city in the month of December.

Of course, this incident is actually fictionalized, it is from the Tang Dynasty notebook novels, and there is no record about this inside the official history, besides, Pei Yan's identity is very special, to kill him so a minister of Guanwei, it is not by splitting the word to deal with it.

So why Pei Yan will be killed? I think the main factor, or in his heart against the Empress Wu claimed the throne, although he followed the Empress Wu to abolish Li Xian, that is because at that time, the Empress Wu was still the country's empress dowager, so he cooperated with the empress dowager, you can firmly control the emperor, so that they can hold the power, after all, the Empress Wu, a woman, there is no way to formally dominate the courtroom.

But if she wants to be the emperor, it's different, then it's logical to take over the court, the Empress Wu did have this intention in her heart, but Pei Yan was against her at this time, not only resolutely requesting the Empress Wu to return the power to the emperor, but also taking the opportunity to put pressure on the Empress Wu by taking advantage of the fact that Xu Jingye rose up to the army, and his practice, in addition to provoking the Empress Wu, did not have any too good an effect, and so he was eventually killed by the Empress Wu.

Pei Yan and Li Xian's struggle, we can understand for the conflict between the imperial power and the power of the phase, the history of these auxiliary ministers, in fact, most of them have some conflict with the new emperor, although the monarchs and ministers are different, but the boundaries of this auxiliary government is not very clear, so a lot of people have transgressed the situation.

The power of the prime minister of the Tang Dynasty is still relatively large, like when Changsun Wuji, these people, can force Tang Gaozong had to bow, then Pei Yan and others, naturally, will be able to put more pressure on the emperor.

But their essential interests, and the Li Tang regime is the same, so these people in the anti-emperor at the same time, will continue to defend the Li Tang regime. It's not unproblematic that Pei Yan would make such a story, and I think it's possible that there was some connection between him and Xu Jingye.

Other than that, just because he did not firmly clear himself after Xu Jingye's rebellion, and instead took advantage of the turmoil to ask the Empress Wu to hand over her power as soon as possible, I don't think anyone would believe him if he didn't have problems.

So the Empress Wu killed him, can not be said to be unfounded, Pei Yan's death implicated a lot of people, like Cheng Wuting such famous generals, but also because of his things were implicated in, and eventually killed by the Empress Wu.

Of course, many of the so-called charges, or later added to Pei Yan these people, they will certainly have some problems, but the charges really do not have to be so big, in the final analysis, these people and the Empress Wu is not the same heart, they are not like the Wu Sanshi such as, resolutely embracing the regime of the Empress Wu, and therefore to get the support of the Empress Wu.

Keeping Pei Yan and Cheng Wu Ting in the picture would only make the Empress Wu's claim to the throne more obstructed. Besides being Li Tang's courtiers, these people were also from some noble and famous families

The Empress Wu was not quite the same, her family lineage was relatively average, and if she wanted to continue to be in power, she had to do a good job of balancing things out, such as figuring out ways to add some people from humble backgrounds, and relying on the promotion of these people to confront these sons of gatekeepers in the dynasty.

Pei Yan is belong to the representatives of these clans, he was suppressed by the Empress Wu is also very normal, with the death of Pei Yan, the Empress Wu also accelerated his own pace of the emperor, if Xu Jingye rise up to the army can cause great pressure, then the Empress Wu may consider the return of things, Pei Yan and others may not be killed, his judgment of the situation is still a clear error.

When Xu Jingye rose up, the momentum is indeed very big, but the strength of the two sides does have a great gap, so Pei Yan should wait and see for a period of time, and then make a choice, he is just too anxious, if you can have some patience, it is not too early to die.

Pei Yan has a good literary talent, but his political sense of smell is really too bad, the high emperor chose him as the auxiliary government of the people, is really the wrong choice, the dynasty is really not a few people can be trusted, most of them are dependent on Wu Zetian.
