I haven't paid social security. Can I pay in one lump sum?

I can't. Social security payment is a long-term process, which needs to be carried out in stages and cannot be completed at one time. The original intention of social security system is to ensure that citizens can get corresponding protection when facing various risks, and this protection needs to be based on continuous and stable payment. Therefore, people who have not paid social security can't have sexual intercourse at one time, and they need to pay it gradually according to the prescribed time and amount.
