First of all, stand up straight, tuck in your abdomen (don't deliberately tuck in your abdomen), fold your spine (make it perpendicular to the ground), relax your knees slightly (relax rather than bend), and be in a very comfortable state.

Then take the coccyx as the midpoint, swing the left and right hips alternately up and down, first slowly, and then gradually accelerate when the body adapts to the frequency and feels relaxed, and other parts of the body should not swing or fluctuate.

Most sago in belly dancing needs to be relaxed, and then relaxed, so that it can become a natural existence and can cooperate with other compound movements. Otherwise, a sago shakes half to death, how can other movements be coordinated? Just like the harmony in the piano, it may take a long time to find the feeling slowly, but once it is found, it is easy to achieve mastery.
