Over 440 pages. Book Size: 8.5" X 11." The ancient art of Astrology practiced in China is distinctively different from Western Astrology. In fact, these two systems of Astrology are so different that there is no comparison or correlation between them. Chinese Astrology is based on the study of the stars, but it is a different group of stars altogether. Of importance is the star Tzu Wei or the Pole Star and the constellations which are closely associated with it. Created with this system is a cycle and the twelve animals which represent each cycle. Unlike Western Astrology which is based on the apparent movement of the Sun through the Zodiac, Chinese Astrology focuses on a Lunar Calendar.
