Hello, I want to pay medical insurance. Can I have sex for two years at a time?

If no policy payment is involved, you can pay the fee for two years at a time:

Medical insurance for employees is paid monthly, and medical insurance for urban and rural residents is paid annually. It involves issues such as payment base and payment grade, and cannot be refunded. At most, it is restricted by the policy of the local social security agency to pay back the money.
