Peng Ci, as the Chinese call it, is a scam where a person will go out in public, pretend to be injured by another person’s clumsiness, and then try to extract money or favors from the person they accuse of injuring them. I’m sure it’s not only a Chinese thing – in fact, I suspect it even explains an odd public interaction my wife and I were confronted with right here in the US a few years ago – but this American living in China was inspired to make what is actually a pretty catchy tune out of it.
