Can rural collective accounts pay social security and medical insurance?

First of all, you haven't figured out the concepts of social security and medical insurance. There are two kinds of social security: employee social security and resident social security. Employees' social security includes old-age medical care, work injury, maternity and unemployment, and residents' social security includes old-age medical care and medical care.

If you work in an enterprise, you can also participate in employee social security. I hope I can help you.
