2. The principle that the five elements are interdependent: The five elements are a material concept in ancient China, specifically referring to: gold, wood, water, fire and earth. The ancients in China believed that nature was composed of five elements. With the rise and fall of these five elements, nature has changed, which not only affects people's fate, but also makes the universe cycle endlessly. The five principles are: aquatic wood, wood makes a fire, fire makes soil, soil makes gold, and gold makes water; Mutual restraint means mutual restraint, mutual restraint and mutual inhibition. The order of mutual restraint of the five elements is: Jin Kemu, Muketu, Tuke Water, Water, Fire and Gold. Therefore, in the ancient geomantic omen of China, the five elements should be considered when deciding the architectural form and choosing the living orientation.
3. Principle of adjusting measures to local conditions: China has a vast territory, very different climate, different soil quality and different architectural forms, and the northwest is dry and rainy, so people live in caves. The southwest is wet and rainy, and there are many insects and beasts, so people live in bamboo buildings with columns. Different geographical locations make different houses. China Feng Shui has different living environments, including the so-called Jingyi House, the deserted house and the valley house. Therefore, in the application of feng shui, each has its own emphasis. For houses in the wilderness and in the valley, due to their close relationship with the surrounding natural geographical environment, more attention is paid to forms and methods; However, due to the limitation of its external environment, Jingyi House often adopts the way of paying equal attention to form and rationality.
