Do you still need to pay social security after paying medical insurance?

No, because medical insurance is included in social insurance. Social insurance is a social and economic system that provides income or compensation for those who lose their ability to work, are temporarily unemployed or suffer losses due to health reasons. The main items of social insurance include endowment insurance, medical insurance, unemployment insurance, industrial injury insurance and maternity insurance. According to Article 8 of the Civil Law of People's Republic of China (PRC), civil subjects engaged in civil activities shall not violate the law, public order and good customs.
