The founder of my schools studied Kenpo under Master Ron Lee. He was a Chief Instructor in Berkeley. Then he started his CLF and TCC training. There is a bit of organizational foundation in our schools influenced from Kenpo. Mostly that we have the idea of techniques in our curriculum that are CLFitized Kenpo techniques at the beginning and intermediate levels. The techniques at the advanced levels seem to be ones Tai Sigung created from scratch. It was interesting to pull up one of our techniques on the Internet and compare the technique Kenpo style vs CLF style and see how the same moves were done with different principles. It was actually a critique some people had of our schools. They claimed that it wasn't "pure" CLF. But really, techniques are a good training tool, and since the principles of the moves are CLF, I don't get the critique. But if it bothers some people, then ok. Whatever works or doesn't work for them. There were a few other things that have been phased out over the years I have been there. We had a few techniques that had a hand formation called either a ridge or a ridged claw (?), but CLF doesn't have that, so it got changed to a CLF style eye poke. Our sash test ceremony changed because it originally had a Kenpo influence. I find myself wondering if the fact that we have "Chief Instructors" as well as Sifu's is a Kenpo influence. CLF itself is a mix of three different arts studied by our founder, Chan Heung. It was founded in 1836. I have read some people list the three styles CLF is derived from, but I don't know that those three styles are proven to be accurate.
