In ancient times, prisoners were always sent to the border to be soldiers. Aren't you afraid that they will disobey discipline or even defect?

Being sent into exile, also known as exile, was called "Liu" for short in ancient China, which was one of the five punishments. The other four punishments were "Kui", "Staff", "Acts" and "Death". Exile was a very serious punishment after the death penalty in ancient China.

The essence of exile is to banish you from civilized society, keep you away from people and interpersonal relationships, form an isolation, and make your life worse than death.

As for escape, the court need not worry. Because in ancient times, most of the places where exiles were placed were located in frontiers and islands. If the exile escapes from the gate of the distribution office, he will face the worst geographical ecology completely isolated from human society, such as desert, wasteland, Gobi and sea. It is not only deserted, but also infested with wild animals, and there is no food source. Without transportation, no one can walk out of this no-man's land with one foot and return to human society. So many exiles actually died halfway before they reached their destination, and the exiles who arrived would not consider fleeing at all.

What's more, the management of the exile is very strict, and even if you want to run, you can't run out. After the exiles arrive, they must register their names, ages, looks and other information. If they escape, the local authorities will arrest them according to the files. And once the escape is unsuccessful, it will be severely punished and even directly executed. Under such strict management and punishment measures, few people will take the world by storm and flee without permission.

To say the least, even if an exile escapes from a no-man's land and returns to human society, it is difficult for him to settle down safely. Ancient local societies were basically clan societies and acquaintance societies, which were managed by the Baojia system, which led to the fact that as exiles, whether they fled back to their hometown or fled to other places, they would be discovered soon. For example, in the Song Dynasty, exiles had tattoos on their faces, which were easier to find.

Moreover, there was a road introduction system in ancient times. As long as you leave your hometown for more than a hundred miles, you have to go to the local authorities to make a road, similar to a letter of introduction or a pass. Exile is escape, where there is no way, basically can be said to be unable to move.

The only thing the exiles can do is wait until one day the emperor finds a way to forgive the world so that he can leave the exiles legally. To tell the truth, besides saving a life, exile is much more cruel than the death penalty. At least the prisoners who have executed the death penalty and their families can help to collect the bodies, while the exiled prisoners are left unattended after death and then left to the wild animals to have a good meal. Even if he is alive, he has been imprisoned and exiled for a long time, and he is increasingly out of touch with human society. Even if he is released one day, he is almost a waste.
