Man has been learning how to get along with nature since he was born. As early as the primitive tribes, they began to have a hazy consciousness of geomantic omen, and they should distinguish the place where they lived from the cemetery and the place where the animal remains were abandoned. This division should be the embryonic form of the meaning of Yang house and Yin house in later Feng Shui. In the tribal period, we had the concept of orientation, understood the relationship between sunshine and cold, and "facing the sun near the water" became the goal of homestead site selection.
During the Yin and Shang Dynasties, divination prevailed and everything had to be decided. King Yin wants to build a city in the northeast of Deer. He asked many times when and where it was auspicious. Turtle divination is not only used for divining houses, but also for state affairs. We can boldly say that the Yin and Zhou Dynasties were the gestation period of geomantic omen.
