Generally, it is the poor who can become executioners. In order to make a living, when they were young, they would learn from the old executioner. Then under the constant training of the executioner, he can become a qualified executioner. The executioner first needs to exercise courage and overcome psychological obstacles. After learning some basic skills, they will practice beheading skills through some small animals such as chickens and ducks, and then when their skills reach a certain level, they will hunt some large animals.
Secondly, as a qualified executioner, you need to have good knife skills. So when they are training, they will draw a line on the wax gourd. When they make a clean break along the line on the wax gourd, without the slightest carelessness, they practiced beheading. The reason for practicing this skill is to let the prisoner die quickly. If the prisoner's first knife doesn't land, he still needs to cut a lot of knives, so the prisoner must be in pain.
Therefore, in ancient times, if the economic ability and living conditions were better, no one would take the initiative to choose the career of executioner. After all, it is a blood-stained profession, which needs strong psychological quality to bear psychological pressure.
