在过去的某些朝代,统治阶级为了把人民束缚在一乡一土,一个措施就是实行严格的户籍管理。一个人要是不经官府批准,随便跑到异地,那就跟罪犯无异,不论做什么事都须提心吊胆。这种制度虽然是以牺牲人民的自由和社会的进步为代价的,倒也颇能奏一时的和谐之功。 In some dynasties of the past, the ruling class, in order to bind its people to one country and one land, one measure was to impose strict household registration management. A person without permission of the government, casually go to different places, it is no different with the criminals, no matter what you have to be nervous. Although such a system is at the expense of the freedom of the people and the progress of society, it is also quite capable of playing a harmonious part.
