Because, for geographical and other reasons, I have not been able to go to my Grandmaster's classes in London for 6 months (I moved away from London) I decided to teach myself a sword form from a book and DVD by Yang Jwing Ming. I had already studied some Chen style sword with the Grandmaster (he teaches Chen style sword as well as Yang style, but just the Yang style barehand form), so I was familiar with basic postures such as the crossed legged and empty stance which are similar in all sword forms. I have now finished my self-tuition and do Yang Jwing Ming's sword form every day in the park as well as the barehand form.
I also bought Yang Zhen Duo's sword form DVD and there are marked differences, to say the least. In fact, although the sequence of movements is the same between Yang Jwing Ming's and Yang Zhen Duo's, the content within the movements is radically different. Does anyone know the derivation of Yang Jwing Ming's sword form, so different from Yang Zhen Duo's? Despite the differences, Yang Jwing Ming's seems very authentic, and every movement is justified in terms of the applications which are presented in detail in both his book and his DVD. Perhaps Yang Jwing Ming's is an earlier version of Yang Cheng Fu's sword form, or perhaps a later one. By the way, I don't want to start a thread on the relative merits or otherwise of learning forms from books and DVDs. I did what I had to do! Regards, Simon
