Social insurance refers to a social and economic system that provides income or compensation for people 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.
