Yang Lu-ch'an invented a brief fighting solo form for each of the main self defence postures in his Old Form. These are called "Root" forms. Every posture has many fighting applications so to make it easier to take the great fighting and healing benefits from the postures, Lu-ch'an gives us a form to practice.
These forms teach us about fa-jing, dim-mak and how internalize the postures thus making the maximum use of one's body for healing and self defence. This 3rd volume takes you from the posture called "Stork Spreads Wings to the postures known as "Brush Knee & Twist Step"". Each form takes its name from the main posture from which is comes.
