Jianzi (), is a traditional Chinese sport in which players aim to keep a heavily weighted shuttlecock in the air using their bodies apart from the hands, unlike in similar games such as peteca and indiaca. The primary origin of jianzi is an ancient Chinese game called cuju, from the Han dynasty (202 BC – 9 AD, 25–220 AD). Jianzi is played on a badminton court using inner or outer lines in different competition settings. It can also be played artistically, among a circle of players in a street or park, with the objective to keep the shuttle 'up' and show off skills. In Vietnam, it is known as đá cầu, and it is the national sport. In the Philippines, it is known as sipa and was also the national sport, until it was replaced by arnis in December 2009.
