I just graduated from automobile inspection and maintenance, and now I am an apprentice in Dongfeng Honda 4S shop.

You'd better stick to it in the 4S shop. I don't know whether to issue a certificate. It seems that you have to take the technical level certificate yourself. You'd better work in a brand's 4S shop for 2 to 3 years to exercise your basic skills! Ha ha. What you learn from your brain is the real thing! If you get a coolie certificate in Dongben, I guess you should start as an apprentice when you go to other brands of 4S stores, but you need to improve quickly if you have some basic skills.
