Hello, I see in your posting there is a business bus from Hong Kong airport to Shenzhen airport that leaves at 8:20am. I actually need to travel to PING SHAN TOWN, LONG GANG DISTRICT in Shen Zhen. Would I need to take a cab from the Shenzhen Airport to the actual place of business I am trying to reach? Would that be the best route of transportation? Then late that same evening I would need to travel to Guangzhou, would the best mode of transportation be by train?
