It seems that one first needs to inform the local technical supervision bureau online, and then report to the local special equipment inspection agency. During the inspection process, the special equipment inspection agency will conduct an on-site inspection, require the necessary inspection materials to be prepared, and provide photographic inspection reports. After the inspection is complete, the agency will issue a report, which can then be used to obtain certification from the technical supervision bureau
