My Sifu has encouraged me many times in the past to work out with other 'Chunners. At the time of my training under him I was experiencing some paralysis on my right side and found Chi Sao and other drills difficult to practice pain free and consistantly when I was there. I've sinced moved away and my condition has improved dramatically for many reasons and he has actually encouraged me to go other places, be humble and respectful, state my reasons honostly and train, train, train..learn, grow etc., main point for me was to improve and for my W.C. to grow. Even when I was living near him he let me know that going elsewhere was cool with him, he was always layed back and mellow, realizing that trying to control others, would eventually push them away. I am sure he would have been hurt had I left his tutelage to train full time elsewhere but his Kung Fu was awesome and he was so cool and such a good friend, why would I? For this and many other reasons, I will train with other Sifu's and people, but he shall always my (final) SiFu and great friend.
