After the exam, I went back to the hall to sign my ID card and put it in the hall. I forgot, is there any telephone contact with the staff in Panyu Hualong examination room?
I don't think it makes much sense for you to ask for your phone number in this case. Might as well go directly to the DMV to find an ID card. Although I left my ID card there, no one else would take it. It should be at the signature place, even if you call, you need to go there. It is better to find it directly, so that the problem will be solved more thoroughly.
