In the Chinese zodiac there are 12 animals designated for the 12-year cycle and they are used in the same sequence.
The signs of the Chinese Zodiac are determined by lunar years that correspond with your birth year. The Chinese believe the animal designated to your birth year has a great vision of your personality and even your destiny.
Chinese astrology deals with the five elements: earth, fire, water, metal, wood.
You simply reference your birth year to find the animal that determines your destiny.
