Why is the yo-yo included in the World Heritage List?

The history of yo-yo can be traced back to China and Greece more than 2000 years ago, and then spread to Europe. In the18th century, this "exotic" "gadget" has become the favorite toy of European aristocrats.

All along, the yo-yo rope has been tied to the shaft, so that when the disc rotates to the end, it can immediately reverse and climb up. The yo-yo fans in the Philippines loosely wound the rope around the shaft and let the wooden plate stop at the bottom to idle (also known as "hovering"). This pioneering work has created countless stunts, such as "cat cradle" and "taking dogs for a walk". Pedro Flores, a Filipino, began to make yo-yos on 1928 after immigrating to the United States, which set off the first wave of yo-yo fashion in the United States. Because it was cheap and durable, it became one of the few successful commodities during the Great Depression.

1932, businessman Donald Duncan bought Flores' company, started to hold competitions extensively to improve his popularity, and registered the trademark "Liu Liu", which made other competitors use names that were not loud enough, such as "Zhuan". Later, Duncan became synonymous with yo-yo. 1962, the company sold 45 million yo-yos in the United States, with only 40 million children. However, in 1965, the federal court ruled that "Liu Liu" became a common term, which made Duncan lose the protection of registered trademarks. Later, Flambeau Plastics acquired the bankrupt Duncan Company and revived the Duncan brand.

Although plastics and metals began to replace wood, the basic design of yo-yo has not changed. At the end of1980s and1990s, several companies made a series of modifications, such as adding side rings, ball bearings and clutches. And the hovering time increased rapidly, from 5 1 91sec in1year to 10 years later. Don Watson, a retired engineer and professional yo-yo player nicknamed "Captain Yo-Yo", said that this "arms race" made "the innovation of design after 1990 exceed the achievements of the past 100 years". The prolonged hovering time has created hundreds of new stunts, which has once again driven the fashion trend, and has continued to this day.

The Origin of You You

2006.7.3

Speaking of the name "Youyou", it comes from the English word "yoyo", which means yo-yo. When you play yo-yo, throw it out and get it back. What is thrown out is "worry" and what is brought back is "luck". Every parent wants their children to be healthy, happy and "carefree", so when leisure is still in the belly, it already has a "name"!

Tracing back to its Chinese meaning, Yo-Yo describes carefree and carefree. In the Yellow Crane Tower of Tang Cuihao, there is "white clouds flying forever without him".

As for the name "Wang Youyang", it is because Youyang belongs to "sheep", and "Yang" is homophonic with "sheep". Yang: Cheer up and be in high spirits. -"Zhang Hengchuan people"]; Fly, get up [only because the court has no control, so the grass grows and the warbler flies. -"Water Margin"]; Carry forward, exert [exert great efforts and show great ambition] -Book of Rites and Music]. And "melodious": describes the ups and downs of sound, continuous harmony. I wonder if you will be as famous as its name in the future.

But no matter how long the song is, I wish him to write melodious life and life songs!

There is another interesting thing about Youyou's name: I visited Tongli in Suzhou one year and met an old man with "skill": he could write poems at will and put his name at the beginning of the poem. With curiosity, I wrote the words "Wang Youyang" on the paper. He only glanced at it and wrote: "Jun praised poetry, and the sound of books spread to the sky. Sail all over the world, and wonderful articles are on the gold list. "

Hehe, after reading this poem, I think "Wang Youyang" is a good name!
