Please refer to the letter above but I am reprinting part of my answer here for your consideration: As the generations come and go the information changes from one
generation to another because people interpret information a little
differently each time. Then even though Wing Chun originated with one person now after generations there are many different ways of Wing Chun we couldn't even recognize. I personally know of three different styles of Wing Chun in mainland China which are different
than I learned. I cannot say who is right and who is wrong, I was just
taught differently. My SiFu, Yip Man, was the one who brought Wing Chun to
Hong Kong. He had taught everyone the same, but we all interpreted it
differently.
