I have a hobby of spinning top. One day, my mother bought me a shiny top in Xicheng Square. I like it very much … Today, my family is playing in Nanyang. In the evening, my father suggested that we go to Nanyang Monument.

Gyro is one of the earliest folk entertainment tools in China, also known as sudra. It is called "Gan Le" in southern Fujian and "Bing Yan" or "Beating an old cow" in the north. Wuqiao area in Hebei Province is called Bo. Guizhou and other places are called géluō not not. Puyang, Henan is called Delou, and Jiaozuo dialect is called Pi Laojian.
Beijing area is called "welding tip" because the welding tip has metal solder joints, and because Beijingers want their children to understand that "traitors" are to be whipped by everyone from an early age.
The upper half of the shape is round and the lower half is pointed. It used to be made of wood, but now it is mostly made of plastic or iron. When you play, you can wrap it with a rope and pull it hard to make it rotate upright. Or rotated by the elastic force of a spring. The traditional ancient gyro is roughly an inverted cone made of wood or iron, and the game is split with a whip.
Gyroscopes emitted by transmitters have been used in modern times. Of course, there are also some "hand-twisted gyros" that are very popular. Gyroscope is a toy that teenagers are very familiar with. Popular all over the world. China is the hometown of gyro. A stone gyro was unearthed in the Neolithic site in Xia County, Shanxi Province, China. It can be seen that gyroscopes have a history of at least four or five thousand years in China.
Gyroscope history
/kloc-More than 0/700 years ago, in the Jin Dynasty, another interesting toy, the bamboo dragonfly, appeared in China. After this toy was introduced to Europe in the18th century, it was called "China Gyro" by westerners. It can be seen that the real gyro arrived abroad earlier than this.
Why is the bamboo dragonfly called "China Gyro"? At first, the word "gyro" was formally put forward by French physicist Foucault in the middle of19th century. In English, gyro means "rotating body". Gyro is a rotating body that rotates on the ground, and bamboo dragonfly is a rotating body that rotates in the air, so bamboo dragonfly can also be said to be a gyro.
In this way, any rotating body can be regarded as a gyro. Like the diabolo we play, the spinning, disc playing, hat throwing and fast spinning ballet in acrobatics all use the gyro principle. Gyroscopes can be seen everywhere in the world around us. As small as atoms and as big as the earth, it can be regarded as a rotating spiral.
