1, ghost dance is a kind of power dance, because it is fast-paced, fast, so some movements are less visible, because he is some columns to complete.
2, one-step flow and two-step quick jump are one of the decomposition movements of the ghost dance, but there is a difference between the two. One-step flow is a step to carry through, a step to complete, only need a beat.
3, two-step quick jump is divided into two beats, two movements, but requires two movements to be completed in an instant, the speed should be fast.
