Yo-yo has a long history. It evolved from diabolo in China, and is deeply loved by the elderly. Later, it evolved into the present yo-yo and became the most extensive sport for teenagers, which was called "dancing on the fingertips". It was originally caused by the Japanese anime "Flying Yo-Yo", and then several TV series "Fire King I" of China Audi Double Diamond Co., Ltd. in 2006-"Fire King II" I》——2007, and finally "Fire King III (anime version)" set off yo-yo fever again. In fact, the screams and flashes in TV dramas don't exist at all, and computer stunts are all fictional. The real purpose of leisure in real life is fitness and entertainment, plus the rendering of "Fire King" D, so it is very popular, just like diabolo. As for the leisure that can scream and flash, it should be some electronic leisure (personal opinion), which is very common. If you install electronics and chips, speakers, etc. Up there, it glows! It's rubbish (for children). It's not a game-specific yo-yo, but a game-specific yo-yo that is very expensive, ranging from hundreds to thousands, because this yo-yo can idle for a long time and can rotate for a longer time, making players behave more smoothly and wonderfully. This is the charm of yo-yo. It is very relaxing to play, and you can put your troubles behind you at once. It is a kind of physical and mental exercise. Fancy is ever changing; This is the dance of wisdom.
