Is it okay to pay only medical insurance and not social security?

You can only pay medical insurance, not social security. Social security accumulated to 15 years, you can choose not to pay. Medical insurance can be paid separately, and generally needs to be paid until retirement age (60 years old for men and 50 years old for women). Please consult the Social Security Bureau for details.
