According to Chinese medicine, Tian Gui (Conception ) is due to the exchange between the Jing-Essence of the parents and the dynamic forces of the cosmos (Yun Qi). These two forces provide the foundation of an individual Ming Yun/Life and Destiny. As the Jing-Essence creates the physical structure of the individual, examination of the different areas of the body can be used to determine the constitution of an individual. One of these techniques is the art of face reading (Kan Xiang).
