I have been teaching Chinese Meta-Physics in particular Qi Men Dun Jia for all these years. What I realised is that most of the students wanted the information and knowledge fast. This creates some fundamental problem. This book took me more than 2 years to write. My intention is to put all the fundamental theories into this book so that readers can have a better understanding of where the formula come from and subsequently use these theories more efficiently. The reason why Chinese Meta-Physics can survive for so long is because it continue to evolve. It can continue to evolve because practitioner has strong understanding of the fundamental. So, I hope to capture these fundamental in this book.This book will not teach you all the Fengshui system. If I really do that, it can fill up a whole library. However, the information here can help you in understanding the Fengshui system that you plan to study later.
