My household registration is in Feidong, and my social security is paid in Hefei. Will I receive my pension according to Feidong standard or Hefei standard?

I don't know if the Feidong you mentioned is in Hefei,

At present, the local regulations for receiving retirement benefits are: those who have been in a certain unit before retirement and meet the requirements of payment period 15 years can retire here no matter where their household registration is.

Those who do not meet the requirements of 15 years will be retired according to their household registration, and will be transferred back to their household registration in other insured places before retirement.

The specific content is very long, so I won't say it here. If you have insurance in other places, it is recommended to transfer to the insured place now.
