Yin and Yang Art in Feng Shui

Feng Shui Yijing says that "one yin and one yang are the Tao". Yin and Yang are two sides of an organic whole, which hide and replace each other. It is impossible to stick to one family and decide the image. Although there is no fixed image, it changes with the Tao, and both can be the upper Tao and the lower device. Tao is infinite and ubiquitous, depending on its use. Use is out, yin and yang are fixed, although fixed, but they also change at any time. So: Yin and Yang are not the same, so they should be one. One is Tai Chi, and the two dominate and interact, transforming into thousands of things.
