However, the unit submits an application for error correction to the provident fund management center, explaining the process, reasons and error correction matters, and can return it after approval according to procedures.

You don't have to worry too much. This is the responsibility of the original unit and won't hurt you. . .

If you find the next company, if you can't record it, the unit will return it to you first and then contact you. As for whether you still pay back the money, it's up to you. . .

However, I am curious about whose personal part they deducted from the original unit provident fund. . .
