The concept is very simple and tactical conciderations are few. By punching and changing your posture, you can maximize your attacking potential while being a minimal target. This Form actually develops very simply attacks which require advanced tactical understanding to defeat.
The important things to remember are to fully go into the stance and maintain the hand techniques. Once the stance is changed the technique must happen. To step into range and not attack is worse than standing still.
This first video is simply the form from four angles. It is a walk through which shows the movements at a moderate pace. It may give you enough information to decide if you would want to learn it.
This second video is of the individual movements, from all four directions.
The purpose of this is to show the movements in greater detail. When learning a form as it is performed by another school, it is often difficult to know when a named movement begins and ends. While many people talk about continuous power, few demonstrate it. Until that achievement is attained, it is necessary to train individual movements and string them together into techniques. Hopefully the knowledge of a defined movement's beginning and end coupled with the name will provide some insight to how you would perform your own unique techniques.
