In my city in NZ, they like to do their tai-chi looking stuff in a park beside the main avenue of travel from the airport, with big banners about the Falun Dafa and Friends Association, but most of the banners are filled with hanzi - which makes me wonder who they're preaching to - Kiwis, or Chinese migrants?
