The Guo Family's Yuanjing is an important work of ancient Chinese divination. It is attributed to Guo Pu of the Eastern Jin dynasty, though its actual date of composition and authorship are uncertain. It is thought to have been supplemented by later generations. Centered on yin and yang, the Five Elements, the heavenly stems and earthly branches, and spirit stars, it is known as the "headquarters of spirit stars."
Its core content covers three main areas. First, it develops a complex system of spirit stars and introduces the original theory of "Hanging, Replacing, and Flying through the Palaces." Combined with the Nine Palaces Flying Stars method, it explores the relationship between the positions and timing of spirit stars, providing a method for choosing auspicious dates. Second, it proposes the "Three Destinies" concept in fate analysis, based on heavenly stems, earthly branches, and the sounds of the Five Elements. It analyzes fate charts through "Hanging Palaces" and "Replacing Palaces," forming an early version of the official-rank fate method. Third, it sets out principles and taboos for choosing auspicious dates for activities such as construction and burial, emphasizing the need to avoid clashes with spirit stars.
The book holds a significant place in history and laid the foundations for auspicious-date selection. It was included in The Five Essential Books on Yin-Yang and the Five Elements during the Ming dynasty. Its theories on spirit stars influenced The Comprehensive Guide to Selecting Auspicious Dates, and it also laid the groundwork for Tang dynasty fate methods and the Song dynasty Ziping method. In conjunction with The Book of Burial, it helped shape early feng shui theory.
The oldest surviving version is a Ming dynasty manuscript. In 2006, Hainan Publishing House used a Qing dynasty printed edition as its base text and published the work as part of The Five Essential Books on Yin-Yang and the Five Elements. Modern scholars have also produced annotated editions. Although its methods for selecting auspicious dates have been questioned by modern science, the book has scholarly value for the study of ancient thought, astronomy, and calendars. It is a key text for understanding ancient Chinese divination culture.
