What's the use of a soldier being a soldier?

Military status is equivalent to household registration. When you joined the army, your account was cancelled from the public security bureau of the local civil affairs bureau, and you no longer exist in society. You already belong to the army. At this time, all you have is the army, and your hukou book no longer exists. It means that the army and society are two worlds. You have a lot of household registration in society and a lot of military status in the army. Generally, after leaving the army, the registered permanent residence will be transferred back to the hometown and returned to the society from the military. If you seriously violate discipline in the army, such as desertion and expulsion from the army, but because it is not a normal discharge procedure, you are hacked and have no hukou.
