What does the PIN on the social security form mean?

The personal identification number on the social security form is the general employee number (i.e. social security code &; #8205; Number) or the employee's ID number.

One? Social security includes: providing for the aged &; #8205; Medical care, work injury, unemployment, maternity insurance, etc.

Second, social insurance is a kind of insurance required by the state. The state develops social insurance undertakings, establishes a social insurance system and sets up a social insurance fund, with the aim of enabling workers to get help and enjoy insurance benefits in old age, illness, work injury, unemployment and childbirth. China's "Labor Law" and "Social Insurance Law" clearly stipulate that it is the legal obligation of the employer to pay social insurance for workers, which is obviously compulsory by the state, and the employer shall not refuse to undertake this legal obligation under any excuse or reason.
