 Notable exceptions are the Single Whip in Sun-style and Wu/Hao style t'ai chi ch'uan which finish with both hands open, palms outward.Single Whip is one of the movements/postures most repeated in the solo training forms, such as t'ai chi.Its first appearance in most forms follows the Grasp Sparrow's Tail sequence (peng, lu, ji, an) and is seen later in Snake Creeps Down.
