Pakua Chang shares many if not most of the basic principles of Tai Chi Chuan. In teaching about the relationship of Pakua Chang, Tai Chi Chuan, and Hsing Yi Chuan I have used the analogy of making bread. To make bread you need the basic ingredients; flour, water, salt, sugar, and yeast. However, depending upon the amount of ingredients and the method of combining them you can make many different kinds of bread. Pakua Chang, Tai Chi Chuan, and Hsing Yi Chuan are like this analogy in that they all share the same basic fundamentals but differ in how they are combined and executed.
