The labor contract will not be renewed when it expires, but the social security will continue.

Legal analysis: if the unit fails to renew the contract upon expiration, it shall notify the employee 15 days before expiration. If the unit fails to renew but continues to work after the expiration, it shall be deemed as automatically renewing the contract with no fixed term. If you resign personally, the company doesn't need to pay compensation. Once the labor contract is terminated, the company should stop paying social security for you. If the company continues to pay compensation, it is the loss caused by the company's work mistakes. You can negotiate with the company about the proportion of overpayment of social security.

Legal basis: People's Republic of China (PRC) Labor Contract Law.
