Shanghai works in a street office and pays old-age insurance.

Hello, I am from Shanghai, too. I personally went to the local street office to go through the relevant formalities and pay social security. Paying social security by yourself only includes two insurances, endowment insurance and medical insurance. If you want to pay other maternity insurance, industrial injury insurance and unemployment insurance, you must pay it in the name of the affiliated unit. As for the standard for individuals to pay social security, you can also go to the social security center to ask. In Shanghai, as long as your child has paid maternity insurance before, and is registered in this city and is a family planning, you can enjoy the expense reimbursement and allowance in maternity insurance.
