There are several Chinese martial arts known as Snake-Boxing or Fanged Snake Style (Chinese: 蛇拳; pinyin: shéquán; literally: 'snake-fist') which imitate the movements of snakes. It is a style of Shaolin Boxing. Proponents claim that adopting the fluidity of snakes allows them to entwine with their opponents in defense and strike them from angles they would not expect in offense. Snake style is said to especially lend itself to applications with the Chinese straight sword. The snake is also one of the animals imitated in Yang family Taijiquan (T'ai chi ch'uan), Baguazhang and Xingyiquan. The sinuous, fluid motion of the snake lends itself to the practical theory that underlies the "soft" martial arts.
