Find two strong people to swing the rope on both sides, so as to ensure the good quality of each swing; We also need to find ten people who have good coordination and physical strength and can't jump, which will affect the efficiency of skipping rope. If you want to jump much, you have to act in unison, so you have to have a unified slogan. You can choose a loud person, who can be a rope-wielding person, and shout the slogan "1, 2, 3" to keep the ten rope skipping people in step.
