Wing Chun is a simple system. Having to reach high levels set by gradings and such in order to be proficient is nonsense. Good for people wallets though.I agree.... kinda. I saw this a lot in Xing Yi, where the stance requirements were very strict. When you saw very skilled people performing it looked as though they weren't always sticking to those requirements, but this is misleading. From years and years of stance training they could activate the requirements even if not in outward appearance. It was ingrained in what they did. But of course, to get to that level you need a great deal of training.
I didn't say it had wide stances but the very sunk strong knee clamping idea is not good IMOI hear what you're saying - though the YKS Wing Chun doesn't seem to me to have really wide and deep stances, more mid-to-narrow stances that are deep (very sunk, very strong knee-clamping - for want of a better expression). For boxers, well, boxers need a stance and method of moving that works well for boxing.
Of course movement varies but the stance should be natural. You wouldn't run the 100 meters sat on your backside.Add in grappling and the stance and movement might be different, adding in kicking and kneeing and again the stance and movement might be different. Add in a weapon... etc, etc.
Yes he did have his own way but his views on some MA systems and their unnatural behavior was justified.Regarding Bruce Lee.... well, he had his own way Right or wrong... Enter the Dragon is still Kung-Fu-Movie-Cool.
In order to maximize our potential there is a certain amount of criteria required to function in a fight. We are not animals that have wings, 4 legs, fangs and talons so a lot of Kung Fu systems are full of nonsense based on animal behavior. I like Ving Tsun because its natural for human beings although the stupid human beings have destroyed it
