Tai Chi, Confucianism and Feng Shui all seem meaningless when you witness the cabin behavior and queue etiquette.
I think the point is that Confucianism was attacked on the mainland under Mao, with a general decline in couth that the PRC government now recognises as a problem. Big difference in behaviour between Chinese people in the diaspora and from the PRC/Mainland/China. Google will find you stories about mainland tourists in Hong Kong and the locals' reaction. Don't know what airlines can do about it, but at a sufficiently high level they might get co-operation from the government of China for an education campaign.
