According to Chinese astrology, the dragon and the tiger are extraordinarily complimentary companions. People sometimes like to combine these two celestial creatures to create or represent the yin-yang symbol, although some Chinese would prefer the combination between the dragon and phoenix to symbolize the yin yang. Both the tiger and dragon are highly respected in Chinese culture. And to this day, there are many images of dragons and tigers that are paired off on walls of temples.
When paired with the dragon, tiger represents the Yin energy (when displayed alone without the dragon, it symbolizes the Yang energy). This fearless animal has always represented the admirable qualities of strength and courage. In feng shui, tiger rules the direction of the West and its component is metal. The white tiger which rules the west parts of every house is considered a yin animal.
Dragon represents the Yang energy. It is regarded as a symbol of good fortune and luck by Chinese people. In China, This mythical animal also symbolizes the emperor (especially the five-clawed dragon) or the male. In feng shui, dragon rules the direction of the east (which is directly opposite to the tiger) and its component is wood. The east is the location of the rising sun, this place is considered a yang location and consequently the dragon (especially the green dragon) is listed as the most yang of all the feng shui animals.
