even if you are already familiar with videos of chinese square dancing, this tibetan routine could be new to you. guozhuang means "singing and dancing in a circle" in tibetan, and it's a kind of folk dance. now it is danced in public places as a way for people to relax and exercise after supper.
unlike the common chinese square dancing, which is popular with middle-aged and retired women, guozhuang dancers are of all ages and genders. when dancing, they create a circle and move clockwise, swinging and shaking their arms.
