Feng Shui believes that everything in the world has the attributes of yin and yang and the five elements. The relationship between man and nature and between man and architecture can be analyzed through the yin and yang and the five elements. Generally speaking, the yin and yang five elements of floors are divided as follows: odd-numbered floors belong to yang, and even-numbered floors belong to yin. The first and sixth floors belong to water, the second and seventh floors belong to fire, the third and eighth floors belong to wood, the fourth and ninth floors belong to gold, and the fifth and tenth floors belong to earth. Above the tenth floor, the order is deduced. If the five elements of the floor are the same as or complement the five elements of the house owner, it is suitable; if they are in conflict with each other, it is not suitable. In addition to the conflicting attributes, some evil spirits from the top management also have to be guarded against. Chuanxinsha: There is a straight cylindrical object in front of the building or residence, which is called "Chuanxinsha" in Feng Shui. It can affect the fortune of the owner, leading to poor financial luck, and the residents are prone to poor health. A bloody disaster. The Sky-Destroying Evil: The two buildings are very close to each other, forming a sword-like gap. This situation will cause the Sky-Destroying Evil, which will make people feel upset no matter whether it appears in front, back or left of the gate. Nervous headaches and other physical symptoms often occur.
