I've just read the entire thread .... Wow! Let me clarify first up that I'm not a Wing Chun stylist. I have hasd some exposure to the art on a personal level with others from the WSL way and the Jim Fung way but not enough to really matter!
A couple of things stand out to me if I may ...
1/. Wing Chun is Wing Chun ... be it this or that lineage, be it in the modern or 1800 sense but the one basic truth of all Chinese Martial Arts is that they must change, evolve to survive within the societies in which they are present! If they don't they stagnate and eventually die.
2/. Hendriks way look only to the past ... in many ways he is in search of the "Wing Chun Holy Grail" .... I've been there, done that with White Crane ..... trust me, it doesn't exist!!!
3/. It's great to look at the past but only so we can enact the art in the present ... otherwise you will be come nothing more than a "historical re-enactor" in much the same way as those who re-enact the knights of old. Great to watch but not even representative of real life-protection. This is something I think Hendrik needs to perhaps come to terms with.
4/. It's not all against Hendrik. If he chooses not to use "His" Wing Chun in such a way then thats just great. More power to him ... but here is the operative thing, it's "His" Wing Chun not everyone else's view. Like it or not I can't see him changing his view in the near or distant future!!!
5/. Hendrik you do ned to seek a little more charity in the way you deal with others! Telling them outright that they don't do Wing Chun or don't understand real Wing Chun (Whatever that may be!) is not going to win friends and influence people and lets be totally honest, you write here, you present your vids here because you are trying to "turn on" people to your point of view rather than accept that others also have their own points of view which just may not concur with your own!
6/. Ancient texts, like those of the Wu Bei Zhi as mentioned by Dlcox are used as reference points from which to build upon not enshrine in concrete! Secondly all History is based on Interpretation. Even the person that writes it down as it is happening will influence that which they write! Sadly when looking at such texts as the so-called "Bubishi (Wu Bei Zhi) all we are truly left with is someone elses "Interpretation" which we then re-interpret to make it suit our own understanding of that written or shared. It is the same with learning a MArt. Weeach make it our own often without knowing! To fight over it all is just plain silly!
7/. Wing Chun is Wing Chun no matter how you spread it or present it!
8/. All Martial arts ... YES ALL Martial Arts were created by man (or women) as an expression of themselves for creative, personal, practical or otherwise meanings. Then came the whole ranking mess ... who awarded the first rank in Wing Chun (who cares!). The truth is that Wing Chun arose from a "McDojo" as did White Crane, Karate, Taekwondo whatever! Someone had to make it all up!!! This is the most important historical truth of ALL Martial Arts! So why fight over it!!! When looked upon from this perspective all the arguments seem pretty silly perhaps null and void?
Relax, enjoy it, do it for yourself and smile .... don't take it all so seriously!
