Is Liuhe Social Security and Nanjing Social Security networked?

Liuhe's social security can't be universal with Nanjing, but if you go to work in Nanjing in the future, you can transfer. You don't have a job now, you can hand it in yourself first. After you go to work, you can make it clear to the unit and go through the relevant formalities at the labor bureau. You don't have to pay it personally, but let the unit withhold it for you every month.
