All these elements provided their concepts of the world. The Taoists later developed the art of control of the body energy known as qi for the performance of supernatural feats. Being well-versed in Geography, they also invented the luopan, which is the geomancer's compass. This compass is based on the principles of yin and yang. Feng Shui experts use the luopan to determine the proper placement of things in the home or office.
Every space has areas coinciding with relationships, wealth, success, health, children and learning.
The objects in each of these areas should be positioned in a certain way to ensure that problems do not enter the home, or if they do, they have to be eradicated promptly. The use of certain colours or plants, as well as chimes and mirrors, are also used to improve a situation.
