where i can get this certificate in Portugal? am i need to attested in Chinese embassy.

Hi, I am not sure which department you need to get this certificate in your country. As in China, citizens can get it from local police station in the city where they reside. Maybe you can get a Single Status Affidavit, attested by your relevant department then attested by Chinese embassy.
