How to participate in social security when children move from rural areas to cities?

According to the different nature of registered permanent residence, there are three kinds of social security. Rural household registration can only buy new rural insurance and new rural cooperative medical system, urban household registration can only buy urban residents' pension and urban residents' medical care, and employees without household registration have another kind of social security. Individuals can't buy social security for urban workers, and they must have a work unit before they can buy it. Individuals can only buy new rural insurance, new rural cooperative medical system or urban residents' pension and urban residents' medical care. Therefore, if it is an urban hukou, it cannot be transferred to the countryside, but employee social security can be transferred to the countryside. But only the individual payment part can be transferred, and the overall part cannot be transferred.
