Upload the video of "Smecta" (step 18) of the disco square dance of Laizhou Dance Youth Dance Team to share with you. There is no explanation for the decomposition action.

Only 18 steps, the action is relatively simple, and it is jumping back and forth. I suggest you download the video to your computer, and use a speed-adjustable player (such as Baidu video, QQ video, Storm video) to slow down the playback speed, watch it repeatedly, and count the steps to learn by yourself.

I wish the dancers a happy dance!
