Master Chen Sheng-Yu analyzes in this DVD the 64-movement Er-Lu Pao-Chui form, also known as ?cannon? form, the most technical, practical and efficient exercise of martial application in Chen Style. Pao-Chiu is only taught when the student has a very advanced 1st Yi-Lu form. It is performed with small circles in a quick and explosive way. It is easy to learn but difficult to perform, however, once the necessary precision is acquired, it can quickly increase the martial strenght of the student and help us explore the paths of Nei-Jing (internal energy).
