QZSY — Seven Governors Four Remainders (七政四餘概覽)
Qi Zheng Si Yu (七政四餘), abbreviated QZSY, is the authentic Chinese planetary astrology system built upon real celestial bodies observed in the sky. Unlike Zi Wei Dou Shu (紫微斗數), which employs algorithmically derived imaginary stars, QZSY tracks the actual positions of the Sun, Moon, and five visible planets — Mercury, Venus, Mars, Jupiter, and Saturn — along with four mathematical shadow points. It is the most astronomically rigorous of all Chinese destiny-analysis systems and occupies a unique position within the Five Arts (五術) as a Destiny (命) art that directly mirrors Western and Vedic astrological traditions.
Historical Transmission
The origins of QZSY trace a remarkable intercultural journey. Hellenistic astronomical and astrological techniques — developed in Ptolemaic Egypt and the Greco-Roman world — travelled eastward through Indian intermediaries. The Indian text Yavanajataka (literally 'Sayings of the Greeks') preserved and adapted Hellenistic methods into the Indian context. During China's Tang Dynasty (618–907 CE), Tantric Buddhist monks — most notably Amoghavajra (不空金剛) — transmitted Indian astronomical and astrological knowledge to the Chinese court. The Kaiyuan Zhanjing (開元占經), compiled under Tang imperial patronage, preserves much of this transmitted knowledge and includes direct references to Indian planetary calculation methods.
Later transmission waves included Persian and Arab astronomical contributions during the Yuan Dynasty (via the Huihui Li 回回曆, the Islamic calendar adapted for Chinese use) and Jesuit astronomical reforms during the Qing Dynasty, documented in the Tian Bu Zhen Yuan (天步真原). Each wave refined the computational precision of Chinese planetary astronomy while the interpretive framework remained distinctly Chinese.

- Xing Xue Da Cheng (星學大成): An encyclopedic Ming Dynasty compendium by Wan Minying (萬民英), integrating multiple schools and methods.
- Tian Bu Zhen Yuan (天步真原): A Qing Dynasty work incorporating Jesuit-transmitted European astronomical precision into the Chinese framework.
- Xing Ming Zong Kuo (星命總括): A concise Song/Yuan era methodology manual.
- Qi Zheng Si Yu Quan Shu (七政四餘全書): A comprehensive manual covering the complete system.
The Eleven Celestial Bodies
QZSY charts plot eleven celestial factors: the Seven Governors (七政) — Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn — plus the Four Remainders (四餘) — Rahu (羅睺, ascending lunar node), Ketu (計都, descending lunar node), Purple Gas (紫氣, a Jupiter-related mathematical point), and Moon's Apogee (月孛). These eleven bodies are plotted within the framework of the 28 Lunar Mansions (二十八宿) and the 12 Ci (十二次) divisions, creating a natal chart that maps the actual sky at the moment of birth.
Position Within the Five Arts
As a Destiny (命) art, QZSY sits alongside BaZi and ZWDS but offers a fundamentally different analytical lens. Where BaZi analyses the elemental chemistry of time-cycles (GanZhi) and ZWDS constructs an algorithmic palace-star matrix, QZSY reads the actual celestial configuration. This makes it the Chinese system most directly comparable to Western natal astrology and Vedic Jyotish, sharing common Hellenistic ancestry with both traditions.
