look at 5 aggregates of buddhism..... language & discovery were primitive back then... people didnt know what elements were back then.. they use metaphor to explain what they discover from their observations

500 years from now... do you think what edison invented known as light bulb as primitive and useless? and say what he use in his design is useless?

"The supernatural idea of qi, is that your body can contain some form of energy other than the normal calories burn to kinetic energy."
- Acupuncture is based on this system of Qi. Has science proved that acupuncture is quackery?

"Anyway, talking about kung fu, it is discovered that chinese martial arts are not as efficient as others (anybody watch the measurement on astro?)."
- This sounds patently untrue. Just who or how did they 'discover chinese martial arts are not as efficient as others.'? What do you mean by efficient? In disposing of one's opponent as in killing him? Not as efficient as others- what others? Karate? Western boxing? MMA? BJJ?
Those astro documentaries gave measurements like force and speed. We are talking about the limitations of the individual here and not about the art itself.
- Mas Oyama, the founder of Kyokushinkai Karate had a run-in with a 50yr old kungfu master in Hong Kong.
- Kenichi Sawai, with black belts in karate, judo, kendo etc was soundly thrashed by a 50yr old kungfu master in China. He stayed on in China to learn the art, returned to Japan and asked for permission to rename the art TaiKiKen.
- Bruce Lee was always talking about the 'classical mess' that was traditional kungfu. An incident took place behind closed doors in San Francisco with yet another 50yr old kungfu master. Most ppl have stopped relating the incident cos both parties have passed on.

"That explains Bruce Lee's westernization of the arts."
- Bruce Lee was never taught the entire system of Wing Chun. Left with and incomplete system he had to improvise. You will have to dig a little deeper as to why he never inherited the system in it's entirety.

"A not related example, even the nanchucks which ppl think are hard hitting, actually have less force than if you hit directly with a stick of the same length."
- This boils down to speed and force.Maybe nunchucks don't hit as hard as a pole but it may be a whole lot faster. So does that mean speed is not as efficient as force?
Correct me if I am wrong. Force = Mass X Velocity
In Wing Chun there is the paradox of the 1inch punch. How much velocity can be generated from a distance of 1inch in a punch?

Answer me this, did I say MMA was not effective as a martial art? Did I say Bruce Lee was wrong in what he did with his JKD? Even his master never placed any emphasis on this power of Qi, so when you manipulate your argument this way > "..prove bruce lee to be wrong in mixing the method in various martial art style and not study the power of qi", then you are by inference saying that Yip Man's system of Wing Chun was about the power of Qi which is misleading to say the least.
