Qin Na (Chinese: 擒拿; pinyin: qínná; Wade–Giles: ch'in na) is the set of joint lock techniques used in the Chinese martial arts to control or lock an opponent's joints or muscles/tendons so they cannot move, thus neutralizing the opponent's fighting ability.
[2] Some Chinese martial arts instructors focus more on their Qin Na techniques than others.
The southern martial arts have much more prevalent reliance on hand techniques which causes the practitioner to be in closer range to their opponent.
Along with Fujian White Crane, styles such as Northern Eagle Claw (Ying Jow Pai) and Tiger Claw (Fu Jow Pai) have qinna as their martial focus and tend to rely on these advanced techniques.
Styles such as Eagle Claw (Yīng zhua quán 鹰爪拳), which includes 108 qinna techniques, Praying Mantis (Tánglángquán 螳螂拳), the Tiger Claw techniques of Hung Gar (洪家), and Shuai Jiao are well known examples.
