The characteristic of flash music activities is the convenience of dissemination.

Flash mob is the abbreviation of "flash video" or "flash action". It is a hippie behavior that has recently become popular in the world and can be regarded as a short-lived performance art. To put it simply, it means that many people use the Internet or other methods, in a designated place, at a clearly designated time.

Unexpectedly perform a series of designated songs, dances or other behaviors at the same time, and then quickly leave. "Flash mob action" is performance art purely for fun or commemoration. Its main characteristics are that it is unorganized and disciplined, with only participants and no initiators.

Flash mobs first appeared in New York in 2000, and later expanded to Europe, Asia, etc.

The flash mob first originated in Manhattan, New York, USA in March 2000. At that time, an organizer named Bill gathered more than 400 people to worship a mechanical dinosaur in Toys R Us in Times Square, New York. After 5 minutes, everyone suddenly left quickly, and the flash mob became famous.

Flash mob is a kind of urban fashion culture. It is a friendly joke that modern people play with the world when they are busy. Most of them said that if the activities were well designed, they would take the initiative to participate. Of course, some people adopt a conservative attitude because they are worried about causing misunderstandings.
