A long rope shook at both ends, and I jumped in it. This is a skipping rope. According to public information, the lyrics of the skipping song are a long rope, and both ends are shaking. I jump and jump in the rope, like a dancing butterfly, more like a swallow flying in the sky, jumping out of the pattern one by one, jumping tall and strong. Jumping rope song belongs to one of nursery rhymes etudes series.
