There is also an obscure Southern Snake Style (Chinese: 蛇形刁手, pronounced as "she ying dil sao"). In this style of snake kung fu the force and techniques are softer than traditional southern styles. Besides straight punches and bong shou as widely used in Wing Chun, this style also employs butterfly-buddha palms, the hook, upper cut, and gui quen (back fist) as central techniques. Biu tze (thrusting fingers) techniques resembling snake attacks are the secrets, and hence, the name of this style. There are multiple kicking techniques, as varied as typical northern styles with high kicks, but also typical are below-the-knee kicks seen in southern styles. There are six fist sets, two stick sets, single sword, short double swords, and other traditional weapons.
