The newly insured employees who have participated in the basic medical insurance according to law and paid the premium continuously for 1 year (excluding the overdue period) (including those who re-entered the insurance after the payment was interrupted for more than 1 year) shall enjoy the basic medical insurance benefits in accordance with the regulations.

brief introduction

For endowment insurance and medical insurance, social security is cumulative. As long as you have accumulated the corresponding years before retirement, you don't have to pay it back.

However, in some cities, such as Beijing, Shanghai and Guangzhou. The welfare of buying a house, buying a car and going to school requires foreign residents to pay social security for a certain period of time. When calculating the time of continuous payment of social security, part of the treatment is counted as continuous months. Therefore, if the payment is cut off halfway, you can find an agency to pay back the social security and realize continuous payment.
