In fact I saw them in the Brooklyn Costco in the second floor on January 11th. One asian man with 2 female compatriots handing out flyers; which was really weird to me. I've seen those flyers weeks before all around the city... The marketing ability of the show is impressive. You really do not see this in most broadway shows... especially one that will only run 9 days.

Some search comes up sporadic mentions of the Falun Gong and it kinda makes sense because for a long time back I use to see groups protesting China's treatment of Falun Gong. However that's kinda silly and could be more China's propaganda machine.
In the end I do not know. Anyone have more clues to this? Seems a mystery to me but maybe it's my imagination.
