There are test sites in Shantou. I took the high-voltage electrician operation certificate in June and was authorized by the Southern Electricity Regulatory Commission. After two weeks of training, I will take the theoretical and practical exams, and I will be able to get the certificate in about one month after passing the exam, which is estimated to be about 1500!
