This is probably a long shot as he doesn't seem to be very well known but...
Is anyone here familiar with Li Jin Fei, who was one of T.T. Liang's teachers? I became curious about him after reading his name in Steal My Art. He was said to have taught Liang the sword tassel art and I've seen it written that he was a Tai Chi teacher but elsewhere I read that he did Shaolin. From what I can gather it seems he was one of Liang's later teachers and I think he met him in Taiwan in the 1970s.
I emailed some of Liang's well known students about him. Ray Hayward and Gordon Muir said they have a video of him but they haven't posted it anywhere as far as I know.
