I haven't heard that one. Can you show me some examples of what you mean?
Examples of force against force? You've got to be kidding! Avoiding crashing force against force is at the core of ...my.... WC/VT. I've encountered this in at least three lineages. This is the essence of what the WC origin myth is all about. Ideally, if an old woman (Ng Mui) or young girl (Yim Wing Chun) couldn't make it work ... it isn't Wing Chun. Please don't tell me that this concept is foreign to you!
