You should have paid the social insurance for the first three years when the original enterprise went bankrupt. Now that the nature of the enterprise has changed, the previous debts should still be recovered from the previous unit. You can ask the rear office of the original unit or the competent bureau (office) of the original unit to pay the insurance for that period, or they will come forward to solve it for you.

If your request is rejected, shelved or delayed, you can appeal to the labor and social security department or apply for arbitration. When appealing, the respondent is not your current unit, but the original unit or the competent department of the original unit.

But it's a little late for you to care
