Ha! No, From what I've read it would not have been Master Ip or any of the old school Sifu's that would have popularized any of the Kung Fu arts for street fighting with emphasis on boxing. Now, WLS, William Cheung, Bruce Lee, Hawkins Cheung ... a different story. They evolved in Hong Kong developing their skills during a time when sport fighting was really starting to take off around the world, slowly but surely. Just like rock 'n roll.
* Based on interviews with Ip Man's Foshan, Mainland students (10 or so) you would have to say that they learned a more "Foshan style" and those who learned in Hong Kong, a more streamlined (civil) version of the same base art. Just as effective considering the teacher.
