Why did the company only buy old-age insurance for the social security I bought?

First of all, it is illegal to pay you endowment insurance, because the state stipulates that you must pay five insurances and one gold.

Secondly, if your friend has paid five insurances, even according to the minimum standard, it is impossible to pay 1 10.

I suggest you go to your personnel department to ask if you only paid the endowment insurance. If so, you can take the labor contract to arbitration, and you can sue one for approval.
