This volume carries on from V. 4 covering those postures and movements from the Old Yang Style of Yang Lu-ch'an from Tripping Repulse monkey to and including Needle At Sea Bottom group of postures. 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.
