About: Whether played competitively on a court, or as a fun group game, the sport of "Jianzi" is an incredibly popular hobby across China for people of all ages. The aim of the game is to keep the heavily weighted shuttlecock in the air using all parts of the body other than the hands. Many streets and parks in China feature large groups of people taking part in the game, showing their skills as they aim to keep the shuttlecock in the air as long as possible. Particularly skilled players use special moves such as the back heel and overhead kick to impress spectators. The shuttlecock itself, also known as a "Chinese hacky sack" or "kinja", typically has four feathers attached at the base by a number of washers, weights, or coins to give it the weight required. The combination of heavy and light materials creates the perfect balance to ensure an accurate movement. Due to the widespread availability and low cost of the materials used to create the shuttlecock, Jianzi can be enjoyed by people of all backgrounds throughout the country. As a formal game, Jianzi is played on a court similar to that of badminton and involves either individuals or teams trying to keep the shuttlecock off the ground and over the net. However most popularly played as a fun group game, Jianzi is a very social sport involving large numbers of people of all ages making it an important part of Chinese social culture.
