First imitate each action in front of the mirror, including the connecting tracks of the actions, and then connect them in series. In the process, you need to understand the force exerting points of the limbs. Some trajectories are achieved through muscle exertion, while others need to be relaxed and "thrown" by exerting force from other parts of the body. Otherwise, the whole body will be too relaxed or the whole body will be too competitive. Finally, get into the mood and dance with the music. In short, in theory, dance is a series of poses and their connected trajectories. After learning it, you can feel the effort, and after you feel the effort, you can become emotionally involved with the music.
