Let's talk about one side first, the left hip is relaxed, the right hip circulates in the horizontal direction of left-front-right-back, and the right leg naturally swings with the span. Don't look at the players behind here, they are not the same as those in Duoyan Zheng, and the opposite direction is the same.
Double-sided, 1, horizontal figure 8 (figure 8 lying down), in fact, is the single side above, and both sides rotate. The whole feeling is like moving back and forth, but the crotch is circled. And the front crotch should be pushed forward
2, vertical plane, knees slightly bent, thighs tightened, draw a semicircle on the hips according to the lower part of the circle.
That's about it, my own understanding, you try to imagine it as a woman.
