Social security problem, please help.

1. Where social insurance is paid, designated medical hospitals will choose which area to facilitate medical treatment. 2. The reimbursement rate of medical insurance should be similar, even if the reimbursement rate is different, but if you are a resident of Weifang, can't you go to Beijing to see a doctor in case of illness? I don't know about the pension in other places, but even if I pay in Beijing, I can't answer how much the pension can reach, because it has something to do with the payment base and working years over the years. It's good to pay anywhere, and there will be some protection when you reach retirement age. Regarding where migrant workers receive their pensions after retirement, it still depends on where your household registration is or where your long-term residence is. The principle is to receive it in your long-term residence, which is also convenient. As long as you have paid for fifteen years, you can receive a monthly pension. 6. Where to pay depends on where you choose to work and who will pay, which is also the unwritten payment principle of social insurance. 7. Regarding the last question, as I said before, pensions are generally calculated and paid in the domicile or long-term residence. For reference only.
