Do landless peasants still pay medical insurance after buying social security?

Yes, you have to pay medical care and social security.

Land-lost farmers still have to pay medical insurance if they buy social security. Social security and medical insurance are two different kinds of insurance. Social security covers pension, medical care, work injury, unemployment and maternity, and medical insurance focuses on reimbursement of medical expenses. Social security and medical insurance are paid separately. After land-expropriated farmers buy social security and pay the corresponding social security fees, they still need to pay medical insurance premiums according to regulations in order to obtain reimbursement and compensation for medical expenses. Only in this way can we ensure that the landless peasants get comprehensive protection and welfare in medical care.
