Ip Man, as portrayed by the 3 movies, really show a neat Ji-lead psychology. I would say TiSe is really the character being portrayed here (I dunno what the real Ip Man's type was).
Never wanting to start fights. Always "centered" in both his fighting style and his views. Always worried about the etho-logical implications of actions (balanced J-lead) Always concerned with rightness of conduct.
But also...
Always independent Has rigid posture Never liking to "owe" anybody anything (to the point of stubborn refusal for work, until it gets shameful) Always taking every action, however small, with the same level of calculation/seriousness that he places on his fighting techniques.
Have you guys seen the movies? What do you guys think?
Wing Chun
I actually studied this for about 1.5 years back when I was a teen. This style is interesting because it's very "reactive"; it hardly makes the first move. It puts a great deal of emphasis on keeping your 'center' and focuses on using your opponent's weight against them. It is very minimalistic, non-flashy, and conserves it's energy very effectively.
As such, you can be very good at Wing Chun while having a very thin build, not a lot of muscle bulk. As with so many East Asian elements, the imprint of Ti is seen in several of their philosophies and lifestyles. This certainly translates into Wing Chun, for me, I think.
