What should I do without a diploma in Yangzhou Electrical Engineering Examination?

No need. You don't need a diploma to go to the local Fangtong educational institution in Xuzhou to take the electrician certificate. Just sign up for an electrician training class. Usually about a month's class. After studying, you can pass the exam and get the primary electrician certificate and operation certificate. Registration requires three 1 inch bareheaded photos, 1 copy of ID card, 1 physical examination form of hospitals above the county level.
