I don't want to debate it, but I hope I do it as closely as possible. The proof is in the pudding. The fact that I learned from many different people is not important. As time went by, I changed my teaching style, tried to be more systematic, and formulated my own terminology. I developed my own schedule.
Some people are able to pick it up and see results in a short time.
In 1973, Master Chu opened the doors of the Tai Chi Chuan Center of New York, in the heart of Times Square. Back then it was a seedy neighborhood filled with X-rated video stores but it was easy to access by subway from all parts of the city. Back then Sifu Chu used to spar with students, and people seemed to want proof of his mastery. I literally had to throw people out of the school many times, because the neighborhood was kind of rough. People would walk in, make a comment, and I had to physically throw them out.
