The social security item 4 10 for individual tax collection is generally a fixed number of payers, but the codes in each place are different, and many of them do not need to be reimbursed separately by the social security bureau. It is most accurate to consult the local social security bureau specifically.

Social insurance types 1 1, 2 1, 3 1, 33, 4 1, 5 1 refer to pension, unemployment, medical care, work injury and maternity insurance.
