Is the length of service of contract workers 92 years ago counted as the length of service stipulated by social security?

Dear you, in the contract before 1992, if employees have working years, then all working years are regarded as payment kilometers, because after 1992, our country began to implement pension planning, so 1996, two-thirds of the country began to implement pension insurance, until1996. Therefore, the length of service of all contract workers before 1992 is calculated according to the kilometers of deemed payment, which means that the state recognizes your payment, but it is not the actual payment period. This deemed payment period is only calculated after you retire, and your actual payment period is combined with the deemed payment period.
