The tourist source data is interesting, and backed up by observations from here. So that is yet another course helicopter pilots need to take, to add value to our CV's -Mandarin...
Rob makes an interesting point that the Japanese were helicopter aware before they came to Aus, and so thought little of buying a trip over the harbour, or round the rock, or businessmen chartering to a site. There are lots of EMS, police and ENG machines in Japan.
In China, the only helicopters most of the public see are military. They will need a strong marketing effort to get them used to the idea, but from HK experience, they will get the message quickly as long as it is seen to be exclusively expensive and cool.
Come on you mandarin graduates, get out there and preach the helicopter mantra!
