The first thing you need to do is to get a good deal of money to pay for the work you do.

Nonsense, direct to you answer:

First of all, this thing is not difficult, you are in Shanghai's social security in the first pension insurance to stop, but continue to pay the health insurance, health insurance can not be stopped, interrupted for more than two months of the years of null and void, so the Shanghai that change is now only to pay the health insurance does not pay the pension.

Then the field side of the normal account opening and payment, and so you leave the time to go back to Shanghai before remembering to find the field unit to two materials: 1, proof of separation 2, proof of social security contributions. To these two materials after returning to Shanghai to social security accounts can be combined. The number of years and the amount of money are cumulative superimposed will not have any loss.

Of course, you can also pay both sides normally, after the migration of social security is the same will be stacked.
