The Dragon, Monkey and Rat are the Competitors of the Chinese Zodiac. Having the image of your own animal sign in your animal sign sector activates your good luck for the year, while having the images of your allies allows you to 'borrow' their luck if the outlook for the year is not so good for you. They also give an extra boost of luck in the good years, as well as promote friendship luck, making all your relationships more smooth, harmonious and long-lasting.
For the Dragon, place these images in the Southeast. For the Monkey place in the Southwest. For the Rat, place in the North. The longevity symbols on these animals will also help ward off illness and keep you happy and healthy.
