Positioning furniture or adding enhancing objects, such as a water fountain or a lively aquarium, increases the good chi in the space. A feng shui "remedy," an object like a mirror, plant, string of lucky Chinese coins, or bamboo flute, "fixes" or deflects bad chi from an inauspicious environment or awkward corner. It's that simple -- and that complicated. Feng shui has rules, but it is an interpretive art. Successful designs for attracting positive energy are influenced by many factors and varying approaches.
Historically, feng shui was widely used to orient buildings—often spiritually significant structures such as tombs, but also dwellings and other structures—in an auspicious manner. Depending on the particular style of feng shui being used, an auspicious site could be determined by reference to local features such as bodies of water, or stars or the compass.
