In ancient times, imperial power was supreme, and there was a concept that the king wanted his subjects to die, and the subjects had to die, so were the courtiers really so loyal? The answer is yes, the ancients embraced this idea from an early age, and it has been like this for generations, and it is loyal to the emperor in the eyes of the heart.
In addition, the emperor holds heavy power, if you really disobey, the emperor naturally has a way to solve you, and dare to violate the imperial power, the family will be implicated to a certain extent.
As the saying goes, a companion is like a companion of a tiger, and no matter how good the relationship between the ministers and the emperor is, they are also jealous of the emperor, in case the emperor is unhappy, it may even directly kill him.
In fact, the emperor is also jealous of the ministers, so the emperor likes to cultivate the two factions and let them fight with each other, after all, some ministers also hold real power, in case they conspire against each other, they can't stand it, of course, the ministers who can make the emperor jealous are a minority after all, and the wise emperor will not train the ministers to threaten themselves.

In addition to the ministers, there are many generals, after all, the emperor can not always hold the military power in his own hands, many times have to delegate the power to the generals below.
The emperor needs to rely on them to go out to fight or defend the side, such a person the emperor is jealous? The answer is yes, the emperor is also afraid that this general has two hearts, and the general who has received military power at the same time is also afraid, he is afraid that the emperor will not trust himself.
Although it is said that suspicious people are not used, there is no doubt about the use of people, but the emperor is naturally very sensitive to these, so the emperor also has many ways to control these generals, in case this army changes its mind.
First of all, the simplest is to screen people, and the general who can lead the army alone must have a strong loyalty to the king in addition to his strong ability.
After the general leads the army out on the battlefield, the emperor will naturally have many means of restraint, so that this person can not act arbitrarily, and the lowest-level approach is to set up a lot of deputy generals, so that they and the main general share the rights.
The reason why this practice is low-level is because the ability of the deputy generals is uneven, they share the rights, for example, when transferring troops, everyone needs to agree, so it will be wrong, so this method can only be used on small generals.
For some high-level generals, the emperor will set up a supervision army, these people are plainly to supervise whether the general has anti-thoughts, if there is, it will be reported as soon as possible, or directly solved.
Many of the generals' families also lived in the capital, if they were really opposed, the emperor would kill his whole family at the first time, after all, rebellion can be said to be the first serious crime under the feudal dynasty, in fact, in ancient times, there were very few soldiers who really dared to rebel, and the real successful example of such a success in history is probably a Zhao Kuangyin, no matter how tempting the throne is, there is no fool to do this kind of thing.
The emperor was afraid, in fact, the real fear was the generals, who themselves knew that they were under supervision, so they would act carefully, afraid that the other party would think that they had two hearts.
The power of the supervision army is also very large, the generals are afraid of being framed, the really intelligent generals in ancient times also know how to act low-key, and some generals will do something according to the character of the emperor to show their loyalty.
For example, some people will also ask for some rewards before going out on the expedition, and the emperor will be very happy, which means that this person is very loyal, that is, he wants some glory and wealth, and there is no opposition.
As for those who hold a side with heavy troops, the emperor has countless ways to hold him, but if this person really wants to rebel, the emperor has no way, of course, the premise is that the soldiers follow him to oppose, even if it is reversed, what can it be? Can a soldier in one place fight the entire imperial court? Therefore, after the emperor gave the military power to the generals, the emperor was afraid, in fact, he was more afraid of the generals who held the military power.
