Shenzhen VOA details

i am arriving in hong kong 28/7/17 and was just wondering about the specifics of the VOA. I have previously lived in Shenzhen and am returning, briefly, to see friends. Is it possible to get a bus from the airport to huanggang (as i have done many times in the past, but always with a chinese visa) and get the VOA there, i know that you are required to give the bus drivers your passport for inspection and i thought that a chinese was needed. I appreciate any help you can provide
