Can the social security paid after the agricultural insurance continue to be paid?

First, agricultural insurance also belongs to social security, but it is a different branch. Second, the endowment insurance for urban workers can only be paid by urban workers, not to say that urban workers cannot participate in the insurance. If you are an urban employee, you must participate in compulsory payment, and you can't surrender your insurance, nor can you turn it into agricultural insurance. Third, if you cancel the contract with the unit and return to the countryside, you can transfer to the countryside to continue to pay the rural old-age insurance, and combine it with the urban employee old-age insurance to calculate the payment period.
