I also noticed that among the 12 sets of square fitness dances recently promoted by the State Sports General Administration, 9 sets were led by Wang Guangcheng, and his front demonstration was "mirror", that is to say, he danced what we saw in the mirror. If the person in the video shows his right hand and walks to the right, we should also show his left hand and walk to the left, just as he is you in the mirror, just as you see his direction. Moreover, the explanation video he shot provides the action decomposition of his back. We saw it on his back, so the front and back directions are different. If you want to learn, it is recommended to follow the explanation video (that is, the back).
