In plain words
Certificates can be forged, so what you check is the body that issued the certificate. A testing body must be qualified to issue reports to the public, and the report must carry the CMA mark. The issuing authority publishes the list of bodies on its website, and you can check for yourself whether this one is on it. In cases investigated by the authorities, some "national inspection certificates" (国检证书) that came with the goods had been made by someone the seller found.
