The examination belongs to the labor bureau, but they don't care about the examination registration, and you can't report it yourself, so you can only register at the training institution. For example, when I was in Qingdao, I looked for the name of Aide newspaper when consulting this exam, and I had to report it in advance. The application for the exam will be closed at the end of August, so hurry up if you are sure to take the exam!
