Changquan (長拳 or Long Fist) refers to long-range extended wushu styles like Chaquan (查拳), Huaquan (華拳), Hongquan (洪拳; “flood fist”), and Shaolinquan (少林拳), but this wushu form is a modernized style derived from movements of these and other traditional styles. Changquan is the most widely seen of the wushu forms, and includes speed, power, accuracy, and flexibility. Changquan is difficult to perform, requiring great flexibility and athleticism, and is often practiced from a young age. All nandu movements must be made within 4 steps or it will not count for nandu points.
Nanquan (南拳 or Southern Fist) refers to wushu styles originating in south China (i.e., south of the Yangtze River, including Hongjiaquan (Hung Gar) (洪家拳), Cailifoquan (Choy Li Fut) (蔡李佛拳), and Yongchunquan (Wing Chun) (詠春拳). Many are known for vigorous, athletic movements with very stable, low stances and intricate hand movements. This wushu form is a modern style derived from movements of these and other traditional southern styles. Nanquan typically requires less flexibility and has fewer acrobatics than Changquan, but it also requires greater leg stability and power generation through leg and hip coordination. This event was created in 1960. All nandu movements must be made within 4 steps or it will not count for nandu points.
Taijiquan (太極拳, T’ai chi ch’uan) is a wushu style famous for slow, relaxed movements, often seen as an exercise method for the elderly, and sometimes known as “T’ai chi” in Western countries to those otherwise unfamiliar with wushu. This wushu form is a modern recompilation based on the Yang (楊) style of Taijiquan, but also including movements of the Chen (陳), Wu (吳), Wu (武), and Sun (孫) styles. Competitive contemporary taiji is distinct from those traditional styles it draws from, in that it typically involves difficult holds, balances, jumps and jump kicks. Modern competitive tai ji requires good balance, flexibility and strength.
Nandao (南刀 or Southern Style knife) refers a form performed with a curved, one sided sword/blade based on the techniques of Nanquan. The weapon and techniques appears to be based on the butterfly swords of Yongchunquan, a well known Southern style. In the Wushu form, the blade has been lengthened and changed so that only one is used (as opposed to a pair). This event was created in 1992.
Gun (棍 or staff) refers to a long staff (shaped from white wax wood) as tall as the wrist of a person standing with his/her arms stretched upwards, but this wushu form is a Changquan method of using the white wax wood staff.
