Jianzi (毽子) is a traditional Asian shuttlecock game which originated in ancient China in the Han dynasty.
The jianzi is a shuttlecock fixed with a rubber sole. The object of the game is similar to hacky sack, where the player (or players) aims to keep the shuttlecock from touching the ground without the use of the hands. The shuttlecock is primarily balanced and propelled upwards using parts of the leg, particularly the feet.
The jianzi is also widely played in the Southeast Asia, where it is known as Capteh.
