I used to be in Yangzhou factory, but now I am in Yizheng factory. How to pay the insurance for Hanjiang River?

Your situation generally requires transferring social security payment from Yangzhou to Yizheng, so that social security can be accumulated.

If you don't transfer, you can, but the money you paid before is not easy to accumulate.

Specific suggestions to the local social security department.

I hope it helps you.
