It doesn't have to be in the place where the evidence is obtained, and the special operation certificate is common throughout the country.

The key depends on what operation project it is.

Such as electrician, electric welding, gas cutting, erection, etc. Whether the training institution is approved by the Safety Supervision Bureau;

Lifting command, forklift and gantry crane are training institutions recognized by the Quality Supervision Bureau.

I wonder if I can help you solve the problem. Please add any questions.
