Please ask a big brother to introduce various social security issues in detail.

Social insurance refers to a non-profit social security system with income redistribution function, which is used by the state to prevent and force most social members to participate.

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 social insurance plan is organized by the government, forcing a certain group to use part of its income as social insurance tax (fee) to form a social insurance fund. Under certain conditions, the insured can get fixed income or loss compensation from the fund. It is a redistribution system, and its goal is to ensure the reproduction of material and labor and social stability. The main items of social insurance include old-age social insurance, medical social insurance, unemployment insurance, industrial injury insurance and maternity insurance.
