The Chinese have practised astrology for many thousands of years- they compiled a systematic method of observing and interpreting the heavens long before contact with the Western world was made. Derek Walters traces the history of Chinese astrology from its earliest records to the present and explains the principles on which it is founded. He examines its foundation in astronomical observation, its historical context and methods used for interpreting the portents. Actual Chinese horoscopes from different periods bring the subject to life. An important feature of this new edition is the inclusion of the Tzu Wei system which forms the basis for the latest computerized Chinese horoscopes.
