Between 2 and 5 , the development is real!

This phase has been on my mind since I read it from He Jinbao's paper.  According to HJB, this phase came from a book written by Men Baozhang.  The 2 is referring to the theory of Taichi.  The 5 is referring to the theory of Wu Xing.  It is these 2 principles that we must follow in order to make a real progress in Baguazhang.  As I was thinking about how to apply these 2 principles in to my practice,  I suddenly realized that may be I should learn these principles from  the art that directly related to those 2 theories.  Studying the principle of the movement in Taichi chuan and Xing yi qhaun seems to be a good place to start my quest of improving my Baguazhang.
