Yin and Yang Feng Shui was an ancient traditional Chinese culture. Its theoretical basis was to infer a family's fortune and fate through the influence of geographical environment and weather conditions on the human body. There were two main parts to Yin and Yang Feng Shui-Onmyoji and Feng Shui Master. Onmyoji was responsible for predicting the fate and fortune of family members based on the eight characters, tarot cards, and other astrological theories, while Fengshui masters would choose suitable Fengshui treasures to improve the overall fortune of the family based on the theory of Yin and Yang Fengshui. Yin and Yang Feng Shui had a wide range of applications. It could be used not only to predict the fate of individuals, but also for corporate Feng Shui planning, housing Feng Shui adjustments, and so on. However, it should be noted that although Yin and Yang Feng Shui has a certain scientific and practical nature, it is not a scientific method. The prediction results are only for reference and cannot be used as the main basis for decision-making.
