I'm just glade OP created the topic as "FUK International Departures and Chinese tourists and their duty free" instead of "FUK Chinese tourists and their duty free at International Departures"

Anyway I think these things will improve with time; the younger, urban, tech-savvy generation in China is generally (I presume) aware that these behaviours are frowned upon, eventually as the older generation dies off and the younger ones get more affluent and travel more the situation will change.
