This is a measure to reform the household registration management system. According to the principle of permanent residence registration, citizens' accounts are unified as "hukou", and only "family households" and "collective households" are distinguished, and "farmers" and "citizens" are no longer distinguished. Many cities have cancelled urban hukou and rural hukou, both of which are called family hukou, so family hukou is a new name after the cancellation of urban hukou and rural hukou. China has abolished the distinction between "agriculture" and "non-agriculture".
