Why did you pay social security from 1996 to 1993?

According to Fatu's website, the reason why social security was paid from 1993 1996 was because when the social security account was opened at 1993, although the insured paid employee pension insurance, it might be interrupted for a period of time due to personal or company reasons. According to the relevant regulations, if the insured person starts to pay continuously from 1996, the payment period will start from 1993, but the time of intermittent payment will not be included in the payment period. Only when the local social security account can be established, the subsequent payment period belongs to the actual payment period. If the insured does not pay, this part of the time does not belong to the payment period, nor can it participate in the calculation of pension, and it cannot be regarded as the payment period.
