The Chinese Hacky Sack, called Jianzi in China, is a special shuttlecock sport. It is a colorful feathered article with a spring-loaded base which should not be confused with the Badminton Sport Cork Ball. It is kicked by feet, the goal of which is to keep it in the air for as long as possible. The Chinese Hacky Sack has a history of two thousand years, and can be read about in quite a few ancient books. It was from the Han period in China when people first played it, and it was popular in Liuchao, Sui and Tang periods. In 1933, in the fifth national sports meeting held in Nanjing, Chinese Hacky Sack was formally defined as a national sport. In June, 1961, the Central News movie company made a movie called "The Flying Feather;" it was so successful that it received the Gold Medal of Movies in the International Movie Festival. Starting from 1963, kids were taught how to play Jianzi in elementary schools; it became a popular sport more than ever. Jianzi became known in Europe in 1936, when a Chinese athlete from the province of Jiangsu performed a demonstration at the Olympic Games of Berlin. Germany and other countries were so impressed with it that they began to learn how to play the sport. The World Shuttlecock Championship is an annual event held since the founding of the International Shuttlecock Federation (ISF) in 1999. Until then, various countries took turns organizing championships. Many health benefits can be derived from playing Chinese Hacky Sacks.
