叙述拧拳反掌的练功方法。

On July 12th, 2009, at 5 pm, a lot of fans met at People’s Square in Shanghai. They performed Michael Jackson’s unfinished dance. For one minute, they sang and did the moon walk (太空步) to remember Michael Jackson.

This kind of phenomenon (现象) is called “flash mob (快闪族)”. “Flash mob” is a group of people who meet in a public place to perform an activity for a short time. Sometimes all these people are friends, but usually they are strangers (陌生人) and they find each other (彼此) on the Internet.

“Flash mob” is very surprised and strange. One of the popular “flash mob” activities was in Manhattan, New York City: Three hundred people met in a store and each of them told the shop assistant that they would buy the same size sports shoes, and the shop assistant didn’t know what to do.
