So what is feng shui and why is it so difficult to understand it? Well, for one, feng shui is a very, very old art and science. Its history goes back thousands of years. That is really, really old, which means really, really easy to misinterpret. Because feng shui is such an ancient body of knowledge, it has also been fully “steeped” in cultural stereotypes. This makes it very important to distinguish between the culturally specific expressions of energy and the very essence of any given form of energy.
A grave at Puyang (around 4000 BC) that contains mosaics— actually a Chinese star map of the Dragon and Tiger asterisms and Beidou (the Big Dipper, Ladle or Bushel)— is oriented along a north–south axis. The presence of both round and square shapes in the Puyang tomb, at Hongshan ceremonial centers and at the late Longshan settlement at Lutaigang, suggests that gaitian cosmography (heaven-round, earth-square) existed in Chinese society long before it appeared in the Zhoubi Suanjing.
