Jump ropes flutter like what?

Butterfly. Jump rope like a butterfly fluttering in the air, but also like a line on the ground quickly shuttle. When the jumper quickly rotates his hands, the jump rope presents a graceful arc in the air, as light and beautiful as a butterfly dancing; and when the jumper jumps continuously, the jump rope is like a line bouncing continuously on the ground, forming a rapid rhythm, reminiscent of a fast-running small animal.
