Housing provident fund is still being paid when the previous unit has not been stamped. Can the new company pay in?

No, I have nothing to do with another company, so the new company will not pay. Employees need to seal it up within 30 days after leaving the company. If the company doesn't handle it, the employee can ask the company to handle it, and should go to the housing provident fund management center for deposit registration within 30 days from the date of employment, and hold the audit documents of the housing provident fund management center.
