“Yin -Yang Fengshui (geomancy)” is the knowledge about how people choose and deal with the living environment(tomb is called Yin house while others are Yang houses). It is an art for foretelling the future of the occupant through residential location and environment, housing scale and form, and selected time for building, involving environmental architecture, planning, gardening, ethics, prediction, human body aesthetics, etc. Fengshui is the objective existence of human beings, including sky, land, mountains, rivers, earth, trees and other natural landscape. Fengshui survey is the subjective understanding and practice of the objective. People utilize traditional Chinese philosophy to understand the nature and find an ideal living environment with improving theories and methods.
        Fengshui study is a summary of people's experience in long-term practice. It is based on Yin-Yang and the five elements, I-ching (the Book of Changes), the Eight Trigrams, Hetu Luoshu, the ancient ideas to explain the nature of the universe. Eliminating diseases and disasters, avoiding misfortune, and blessings for riches, honors and safety belong to common social psychology, while Fengshui may influence the fate and luck of a family and offspring, Fengshui proper may benefit mankind.
        Historically, the home environment of human daily life had the greatest influence on people because the orientation, morphology, decorated colors and surrounding environment influenced their physical and mental state even work and career. So when choosing, arranging and decorating a home, the residential Fengshui knowledge and relevant methods are meaningful realistic instructions to be understood and followed.
        The Feng (wind) and Shui (water) prosper the home. We should survey, follow, utilize and transform the nature abstemiously; select and create an architectural environment that is the most suitable for people's physical and mental health, behavior and demand; and change locations, decorate plants, choose colors and arrange furniture to take advantage of the situation. The combination with modern science may make it more scientific, objective and practical to form the modern scientific study of Fengshui. All possibilities will be changed by “YOM Fengshui”, an effective method for inhibiting the occurrence, development, change of diseases and good or bad luck caused by imbalance of Yin and Yang of the human body due to environmental changes, time and space movement, natural material attributes and so on. This is to achieve the ultimate harmony between Yin and Yang, man and nature, and body and mind.
