Who knows where and when to test the fitter's grade certificate in Wuhu City, Anhui Province? I work?

Fitter is divided into three grades: primary, intermediate and advanced, mainly including die fitter, assembly fitter and repair fitter. If you want to take the exam, you must first take the exam for junior workers, and then you can take the exam for intermediate workers after you finish the exam. It takes a long time and practical experience. You can go to the local labor bureau to take the primary, intermediate and advanced exams. Then senior workers, technicians, senior technicians. However, it is more difficult to test technicians, which is equivalent to intermediate titles and enjoys the treatment of engineers. I was still an intermediate in the 1995 exam, and I was still a fitter's level 4 certificate at that time (now it belongs to the intermediate). This belongs to the labor bureau, and it is tested twice a year. You'd better consult yourself!
