It is recorded in the Chinese history that Qi Men Dun Jia, together with Da Liu Ren and Tai Yi Shen Shu are the highest three styles in Chinese Meta-physics. During the ancient Chinese era, the practice of such arts was only privileged to the Emperors or their advisors. Commoners were executed if they were found practising it. Throughout the history of China, Qi Men Dun Jia has played a significant role in shaping China; historical records have shown all the Emperors had practiced this art; from the very first Emperor Huang Di, to and include Chairman Mao Zedong. Many may think that this ancient art may not be applicable in modern times, as it was mainly use for wars in ancient era. This book is a complete re-write of my first book, that provides a clearer insights on how Qi Men Dun Jia is applied and appreciated in today's society, with over 30 new real life case studies.
