How to have my bachelor's degree notarized for work in Harbin China

Must I appear in person to get my degree notarized? Will the document itself be stamped or pressed with a seal? I am already in Harbin and brought an official replacement copy of degree as I don't want to lose my original. Will the replacement document suffice? It's smaller than the original degree. The province began requiring the US Chinese consulate notary this month. The degree I brought already had an Oregon notary seal on it but the government won't accept it.
