I was reading this article linked in another thread: http://www.twc-kungfu.com/articles/ikf_june_1997/1.html I found it interesting. As I am training Duncan Leung lineage, which seems quite "traditional" in concepts, I can only assume that Duncan Leung was being taught the traditional system in private when the students in the regular class were being taught the "Chan Wah Shuen" version. This is the only way I can make the timeline presented make sense. Regardless of the veracity of the article, I find myself again confronted with another example of the one thing I find most distasteful in martial arts, and which is encountered all too frequently, specifically the selective teaching and witholding of "secret knowledge." I believe this is slowly changing, but I still encounter it from time to time. I think it only hurts martial arts, as it leads to internal inconsistencies being propagated as truth which detracts from the art (though not necessarily the effectiveness) The success of the student depends on dedication, training, and hard work, not the acquisition of knowledge of techniques. On the other hand, in the case of Wing Chun, this dissembling ultimately gave us JKD, so maybe it is a force for evolution.
