How to pay back the old-age insurance (unit)

Go to the social security audit department of the Labor Bureau to receive the application for overdue payment, fill it out and affix the official seal. Then take the application form to the social security audit and ask them to draw supplementary documents for you, and take the documents given to you by the audit department to the social security office to handle supplementary business. After processing, you need to deliver a check or cash to the social security finance, that's all.
