Songxi Short Strike is an ancient and secret internal martial art routine passed down through generations. The entire routine consists of 54 postures. The movements are simple and unadorned, combining hardness and softness, slowness and rapidity, and are crisp and swift. Most of its techniques are about taking advantage of the momentum and leveraging the force, opposing the tendons and back bones, and capturing and closing the acupoints. The key points are "respect, tightness, approach, force and cut". Each move and posture is extremely focused on offense and defense. When practiced, it is as smooth as flowing water, free and unrestrained.
