is it possible to notarize my marriage certificate in China?

Thanks for your reply and As per your reply, yeah i did this but they people told me that you must be submit notarized marriage certificate within the year.
(Note: It should not notarize with local office but instead of this it should be notarized with ministry of foreign affairs.)
And which documents are required for notarization? How much Fees for that?

Thanking you,
Cheers,
