The second step is a little leg sweeping. If you walk to the right, step on the floor with your right foot, sweep it with your left foot, then step on the floor with your left foot, and straighten your right foot. This is a step. The second step is to straighten your left foot and step on the floor with your right foot, which will restore the original action and you can continue the second lap. A lot of people do. Pay attention. Simply put, it is to sweep the legs and change the feet, and then the body does not rotate at the original angle.
