英文中，“社会保障包含什么”可以翻译为“What is included in social security”。 Social security is a system of institutional arrangements through which the state provides citizens with a series of basic life protections through legislation and administrative measures. Its purpose is to ensure that people's basic living needs are met and to help them cope with the risks and challenges in life. Social security covers many aspects of welfare and services, and the following are some of the main ones.

Firstly, pension insurance is an important component of the social security system. It provides basic living security for the elderly and ensures that they can maintain a certain standard of living after retirement. The funds of pension insurance are usually contributed by employers and employees, and the state also provides certain subsidies.

Secondly, medical insurance is also a core component of social security. It provides citizens with necessary medical services and protections, ensuring that people can receive timely and effective medical treatment. The funds for medical insurance come from personal contributions, corporate contributions, and state subsidies.

In addition, unemployment insurance is an important measure to provide basic living security for unemployed workers. When workers lose their jobs, unemployment insurance can provide them with certain financial assistance to help them get through tough times. The cost of unemployment insurance is contributed by both employers and employees.

Finally, social assistance is the last resort measure in the social security system. It provides necessary help and support to people who cannot obtain life security through other means. The targets of social assistance include vulnerable groups such as impoverished families, disabled people, orphans, etc.
