The way I know it is Liu He Ba Fa, but then again the form of it I practice seems to be a modernization of the original form. The differences between the form of LHBF I practice and the original being: varying speeds of the movements, the length of some of the stances, and the exaggeration of some of the hand movements. It is considered an internal style, yes. The variation I know has two forms that can either be learned separately or learned together as one long form. I'm not far enough into my studies to tell you it's definitive features and methods of combat application, but what I have figured out shows a lot of deflection. Most, if not all of the deflections keep both hands up keeping you ready for a quick strike or a second defensive/evasive motion. The movements and general practice of the style allows for and teaches fluid transition between one motion to the next. Trapping is present in various movements. I've found a few basic throws, but I've yet to test them. Thus far, though, I can honestly say that it is an incredible style. Again, this is all based on the variation of Liu He Ba Fa that I know, which seems to be a modernized form. I've had to break things down myself, being without direct instruction in the style, but I think I'm doing a decent job as the things I draw from it work very well. What's really neat is if you practice only the hand form(the motions of the upper body only) while standing still you can REALLY see how things work versus upper body fighting. Then, combining those movements with various parts of the stepping form you can create all sorts of attacks, counters, pushes, throws, etc. All of which that I've come across are very simple and very effective. I've only decoded a few kicks so far and they are very basic. However, like with some Chinese Martial Arts, the kicks and strikes may be practiced separately from the Form. Techniques before Form. Anywho, the movements are said to resemble Tai Chi's neutralizing abilities, Ba Gua's evasive footwork, and Xingyi's power as an internal style, but is completely separate from these styles and stands as it's own style. Practicing it you can see these influences fairly clearly. P.S. - I realize I was somewhat vague and listed things that are present in a majority of the styles of Chinese Martial arts, but I was trying to convey it as an all-around style rather than a strategy specific one(Throw-specific, kick-specific, etc.).
