If you see a group of people dancing and singing on the street or in the railway station, you don't need to feel surprised. They are a flash mob(暴民). Who are they? Are they mobs? Don't be confused by their name. Actually, a flash mob is a group of people who gather suddenly in a public place, do something unusual for a brief period of time, and then quickly disappear.
They are usually organized with the help of the Internet or other digital communications networks. The messages may be sent to friends, who send to more people. At a predetermined time, they gather and perform some activities such as exchanging books, coming together to look at the sky, waving their hands and yelling something at the top of their voice for 30 seconds. Then, they quickly disappear before the police can arrive. Using mobile phones, the flash mob can change its place if the first one has been cancelled for any reason.
Bill Wasik, senior editor of Harper's Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob gathered on June 3,2003. Wasik claimed that he created the flash mob as a social experiment designed to laugh at fashion seekers and stress the cultural atmosphere of wanting to be an insider or part of “the next big thing”．
