Hukou is a system of household registration used in mainland China. The system itself is more properly called "huji", and has origins in ancient China; hukou is the registration of an individual in the system. A household registration record officially identifies a person as a permanent resident of an area and includes identifying information such as name, parents, spouse and date of birth. A hukou can also refer to a family register in many contexts since the household register is issued per family, and usually includes the births, deaths, marriages, divorces, and moves, of all members in the family.
