"I am now teaching Wing Chun and am in no position to criticise other Gung-fu systems. I would like to say, however, that many styles ask men to imitate animal positions. Humans don't have the ability to imitate some positions. For example, some animals can leap around from here to there quite easily because they have long tails to help them maintain balance. We humans don't have such a tail to aid us, and so some techniques may not be natural. Therefore, when someone asks me what animal style Wing Chun is, I will always say that it is 'human style'. We use the weapons which nature has given us to the best of our ability."
