Legal basis:

People's Republic of China (PRC) social insurance law

Article 58

The employing unit shall, within 30 days from the date of employment, apply to the social insurance agency for social insurance registration for its employees. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay. If the employer fails to pay social insurance premiums in full and on time, the social insurance premium collection agency shall order it to pay or make up within a time limit. Under normal circumstances, the time limit for paying back insurance depends on the social insurance premium collection agencies and enterprises. The cumulative maximum payment limit of medical expenses paid by the basic medical insurance pooling fund to employees and retirees in a year is determined by about 4 times the average salary of employees in this city in the previous year. The basic medical insurance fund sets the settlement period for paying medical expenses.
