Can the company sue you for paying social security instead of pension?

Of course. According to the announcement issued by the Social Insurance Law of People's Republic of China (PRC), as of July 2023, the employer shall pay the basic old-age insurance premium according to the proportion of the total wages of its employees stipulated by the state, and record it in the basic old-age insurance pooling fund. If the company pays social security for you, but fails to pay the pension, you can bring a lawsuit to the court and ask the court to order the unit to pay the pension insurance premium. You can also complain to the social security bureau and ask the social security bureau to order the unit to make up for it.
