Though I've not seen this particular Form, I've done some of the leg work; what I've on other Threads referred to as the 'monkey squat' where one knee only touches the ground; this way one can go from a low position to one of standing quickly and vice versa and being able to move around near the ground quickly. My training of this method also involves jumping around and landing in the one-knee-down position. The purpose being to get away quickly when for some reason one is forced onto the ground (e.g. being thrown or pushed) and to get away from any follow-up attack while you were down.
The name of this Form as it appeared on the video is "Luo Xuan Chuan" meaning having the characteristics of the spiral of the shells of snails. (Luo = Snail; Xuan = spiral; Chuan = fist)
The write up in the beginning said it belongs to a form of Shaolin martial art; something about a basic form of training where it's a short-strike system with the hands held close to the body and where the quick spiral of the body generates the required power.
Though the whole Form is done near the ground, it was not meant to be like that all the time in actual combat application. Certain individual techniques from the Form are extracted for use only when for any reason one needs to fight near or on the ground or on slippery ground where balancing foot-hold is an issue.
I'll rather be happy than right, anytime.
