Diabolo was originally a courtyard game, but after processing, it became competitive and became a traditional acrobatic project. The player holds two small bamboo poles two feet long in each hand, and the top of each bamboo pole is tied with a cotton rope about five feet long. One hand and the other hand send it around the spool once or twice, shaking it constantly, and ringing when accelerating rotation.

When shaking, the posture is changeable, the rope turns over, and the actions such as winding, swinging, throwing and crossing the bridge are called "chicken on the shelf", "fairy jump", "flying all over the sky" and "twisting". It is also useful to replace diabolo with utensils such as pot cover and wine bottle. Diabolo is a traditional entertainment and leisure project in China.
