Square Dancing(广场舞） In China, the woman who is more than 40 year-old is called Da Ma, and they are a powerful group。They have certain money and most of them don't have work ，So they have lots of free time. They buy house everywhere or fly to the foreign country to buy the brands. Now they have invaded the square at night. when the night comes, a group of Da Ma go to the square, playing the music and dance until 9 o’clock. About few years ago, only few women would do this, but now, as the economy develops, people live a better life, so they begin to find entertainment. More and more people take part in the Square dance . When we go out at night, we may find them dance everywhere. I think Square dance is a good way for people to exercise, they can keep fit.
