How about social security for employees of Xining Special Steel?

Legal analysis: employee medical insurance is compulsory. Working in an enterprise, the enterprise must pay five insurances for its employees, namely, endowment insurance, medical insurance, maternity insurance, industrial injury insurance and unemployment insurance. Among them, individuals pay 20% for endowment insurance, 8% for medical insurance, and the rest are paid by the company. With the gradual improvement of various national systems, regular enterprises now pay social security for their employees. Social security for residents is paid voluntarily by individuals, and currently only includes endowment insurance and medical insurance.

Legal basis: Article 58 of the Social Insurance Law of People's Republic of China (PRC) stipulates that the employer shall apply to the social insurance agency for social insurance registration for employees within 30 days from the date of employment. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay. Employees-free individual industrial and commercial households who voluntarily participate in social insurance, part-time employees who do not participate in social insurance in the employing unit and other flexible employees shall apply to the social insurance agency for social insurance registration.
