Ningbo social security balance can be withdrawn.

If you resign in Ningbo, you can take it out if your account is not in Ningbo. Of course, you can't withdraw the provident fund until you stop paying for one month. It doesn't matter if it is more than a few months. I once helped a colleague to quit after two years.

You can ask someone else to get it for you, and someone else can get you a copy and original of your ID card and household registration book, and help you get the original and copy of your ID card, resignation certificate, notice of stopping paying social security and power of attorney.

I have to hand it in somewhere else. Provident funds cannot be transferred. Only pension and medical insurance can be transferred.
