It depends on how children learn. There are thousands of street dances in Xingcheng, Beijing. If children just want to learn a few finished dances, it is almost enough to spend thousands of dollars to let them learn them simply. If children like street dance very much and want to cultivate it into their hobbies, they can study for a long time, exercise, relieve stress and help bones grow. It is good to learn from their children for a long time.
