However, as China became more and more powerful and prosperous, culture and entertainment aspects of the unprecedented prosperity, the ball has attracted the young people now, only some middle-aged people with the same as the square dance and some. Now the vast majority of Chinese people have realized the true nature of the American Empire, the false democracy, the instigator of war, the source of instability in the world, and will no longer blindly follow the trend.
