When Rose Lee retired from full-time teaching in the 1990s - she sent one of her long-term Taijiquan students (James) to me. He had trained with KF and this is what he said: 'I paid £200 in advance for what I thought was a private session. When I turned-up at the address - it turned-out to be lecture hall - with 50 other people present. KF came out on time and explained he was "too busy" to stay the full hour and that he had filmed the lesson on a 15-min VHS tape. He said we could watch the video "once" - and discuss its content for 45-mins before leaving to make way for the next class. A copy of the tape was £50 for one - £80 for two - and so.' He then walked out the lecture hall whilst two of his full-time students "monitored" the group. I believe this was the late 1990s-early 2000s. James did not exclusively train with me and did not learn the gongfu - the deal seemed to be Taijiquan only - and I allowed it due to my respect for Rose Lee. As for DY - I can only say what others told one of my Chinese students. They said his Longfist did not match the lineages he claimed to represent - with others questioning how it was that he had managed to master so many styles - usually a correlation equalling the number of books he has for sale at anyone time. Now, I do not really know - and you must think for yourself - which I am sure you already do. On a lighter note, I was told about year or so ago - that my style was mentioned on a racist US martial arts site that sets itself up as an arbiter of Asian combat culture. Apparently, this is a single entry from 2011 of all dates! I had honour fights from 1994 to around 2008 - about 100 in all (no pads - no rules) in front of witnesses - and prevailed through them all as tradition demands - but there were some unhappy bunnies (we think one of these made the post in question). From 1994-1998 these fights almost always involved disgruntled ethnic Chinese people looking to finish me off in front of my Chinese family and saving the face of the Chinese community. Imagine that! I used to get these out the way a few minutes to 10am on each Sunday morning so that the classes proper could start. Occasionally, these fights might happen at 11am - as the gongfu section came to an end - with the next hour being strictly internal. These fights were malicious as the opponents were motivated with anger and hatred of an ancient culture - which I respect. As a Buddhist by birth - I like fighting (but dislike greed, hatred and delusion) and I partake with an attitude rather similar to my Muslim brothers. I have always had a good relationship with the Islamic community and was even honoured with teaching a group of their children in Sutton. I think that although we inhabit a material world - the channel to the internal can only happen through a spiritual method. Honesty seems to be the deciding factor.
