I just stumbled upon this forum. It is nice to see that you are discussing my videos. One of them was from mainland China in a great Lion Dance and Kung Fu city called Fat San. I have a lot more that I did not put onto youtube. I have filmed many different Wing Chun styles around the world. I do not claim that these are the best sifus, I only present what I have seen. If you would like to see more of my HK and Mainland Wing Chun videos, please check out my site ph8tel.com . Feel free to leave a comment or uplaod your own videos.
