For employees, social security is what is commonly referred to as the "five insurances and one fund". Specifically, the five insurances are: old-age insurance, medical insurance, unemployment insurance, maternity insurance, and work injury insurance. The one fund is: housing provident fund. Of the "five insurances", according to employee salaries, the general proportions borne by the employer and the individual are: for old-age insurance, employers bear 20% and individuals bear 8%; for medical insurance, employers bear 6% and individuals bear 2%; for unemployment insurance, employers bear 2% and individuals bear 1%; for maternity insurance, the employer bears the full 1%; for work injury insurance, the employer also bears the full 0.8%, while employees do not bear any cost for maternity and work injury insurance. “Housing provident fund”: Specifically, the proportion borne by the employer and the individual is 50% each, calculated based on the individual's average annual salary. National regulations stipulate that the housing provident fund should be no less than 10% of the salary; units with good performance can contribute more, with both employees and the unit bearing 50% each.
