The tiger and dragon beautifully symbolize the yin yang (duality) of the universe. These two symbols of the male and female energies of chi energy have very specific meanings and can be used as feng shui cures as well as works of art.
The yin-yang symbol is usually thought of along with the ancient Chinese religion called Taoism. Yin and yang stand for the two sides of things, like mountains and valleys, or the inside of a bowl (whose shape is concave) and can't exist without the outside of the bowl (whose shape is convex). Taoists thought of yin as the basis for things cool, soft, dark, moist, still, passive, and female.
