Do I need to pay social security in the first month (not the whole month)

You need to pay social security in the first month (not the whole month).

One, because employees have been in the company for less than a whole month, employees will not be insured, and the units and individuals that form labor relations between the two sides have the obligation to handle social security for them.

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.
