With the Jingyuan Mutiny and the rebellion of several jiedushi, it can be said that Tang Dezong's slashing of the domain has failed.
Although Tang Dezong failed, in the whole process, he used amazing facts to prove how stable the power structure originally set up by Tang Dezong was.

The five major clans in the Kwantung joined forces to rebel (Youzhou, Chengde, Weibo, Ziqing, and Huaixi), the two major military regions in the northwest (Jingyuan and Shuofang) joined the rebellion, the forbidden army also went into chaos, the emperor was beaten and escaped from Chang'an City, and later even Guanzhong did not dare to stay, and fled directly to Hanzhong.
In the process, Tang Dezong also made a huge mistake, because he suppressed the eunuch clique, resulting in fewer military and political resources controlled by the eunuch clique most closely related to Tang Dezong's interests.
This rebellion also had a huge mass base, because Tang Dezong supported Lu Qi's wanton conquest and tyranny, which made the people of the world full of opposition.
But even so, Tang Dezong still quickly turned the tables over successfully.
Not only was it successful, but many of the people involved in the rebellion (Li Weiyue, Li Xilie, Yao Lingyan, Tian Xijian, Zhu Zhu, Li Huaiguang) were in high positions, and if they were willing to choose to cooperate with Tang Dezong, they would have a good future, but they all tried to challenge the imperial power, and they all died.
From a rational point of view, everyone will naturally feel that the power structure designed by the Tang Dynasty Emperor is really too stable.
From the perspective of perceptual analysis, everyone will naturally feel that the imperial power is really too sacred, you see Tang Dezong has fallen to that extent, and he can actually turn over the salted fish.
But no matter from which angle to analyze, people will have an unspeakable fear and despair about rebelling against imperial power.
In a sense, this is equivalent to Tang Dezong using his own mistakes to make a destructive and astonishing experiment on the power structure designed by Tang Dynasty. After the test, Fan Zhen found that the power structure set up by the Tang Dynasty Emperor was amazingly stable, and it could not be tossed apart.
In the face of this result, when the feudal town recreates the emperor's rebellion, there will be some unspeakable despair. Because of the last rebellion, everyone tossed and turned, but it was inevitable that the family would be destroyed. If you continue to rebel now, can you still make it more earth-shattering than last time? Estimates are not. That being the case, what good ending can you have now of creating an emperor's rebellion?
It is precisely for this reason that when Tang Dezong passed this hurdle, the authority of the central government of the Tang Empire was not weakened, but on the contrary, it became stronger.
The emperor tossed and turned vigorously above, and at the crucial time there were so many people supporting him. The whole world was against Tang Dezong's voice, but he could hold a steel knife to punish those who had betrayed him.
The emergence and maintenance of the power pattern is the result of the game of countless interest groups, and how will these interest groups choose after the specific game begins? There is too much uncertainty. For similar reasons, many things are unimaginable in advance.
The magic of life, society and history is here.
When people struggle, from an optimistic point of view, imagine that any miracle can happen. From a pessimistic point of view, the same bizarre thing can happen.
History is a game between tens of millions and hundreds of millions of people, that is, looking at the top level, it is also a game between hundreds, or even thousands, of provincial military and national level big figures.
So no matter how high your status is, in the game of so many people, you will also look very pale. Because other people's choices are often difficult for you to control.
To be more specific, the emperor is very bullish, but in the line at a critical time, whether people will stand behind the emperor is really full of uncertainties.
How people will react. They usually make judgments based on their own practical interests.
In the face of their own practical interests, what this big truth, that big truth, is usually pale. But for this reason alone, what kind of reaction people will make is relatively certain. Because this means that all people's judgments are static.
The question is how people will react, and they will judge according to their own future developments.
How things will unfold in the future is fraught with too much uncertainty. Because optimistic estimates are very different from pessimistic estimates.
The emperor seems to have exhausted the mountains and rivers, and now standing behind the emperor, pure interest judgment, do you say it is good or bad?
The chaotic courtiers and thieves are like the sun in the sky, and now standing behind the chaotic thieves, simply judging the interests, do you say it is good or bad?
Different judgments, the results, that are very different.
It's like, you enter the stock market, if you just judge which stock you should buy based on the current ups and downs, it's very simple. However, if you want to buy stocks according to its future changes, this is more difficult.
Because, the stocks that are rising sharply now, will they continue to rise in the future? Different people have different judgments. Of course, the same is true of stocks that are now plummeting.
The stock market feels elusive because its rise and fall is a game played by countless people based on the current rise and fall, as well as the future rise and fall.
In this context, its rise and fall is full of great uncertainty.
But in any case, the Tang Emperor, in an almost desperate environment, still succeeded in overturning the situation and killed many people involved in the rebellion. This fact is enough to make people unnaturally scrupulous when challenging the imperial power.
Of course, after passing this hurdle, Tang Dezong also realized that he had thought about military and national affairs a little simply in the past, so Tang Dezong became more and more conservative in the next twenty years.
