Qi Zheng Si Yu — Chinese astrology by real planetary positions
The seven luminaries and the four shadow planets placed by actual astronomical position at your birth, with the ascendant, life and body rulers, and annual timing.
Seven luminaries, four shadows
| Group | Members | Character |
|---|---|---|
| Qi Zheng seven luminaries | Sun, Moon, Jupiter, Mars, Saturn, Venus, Mercury | Visible bodies, moving at different speeds |
| Si Yu four shadows | Rahu, Ketu, Zi Qi, Yue Bo | Computed points, not luminous; slow-moving, so they set the theme of a long period |
Rahu and Ketu are the two lunar nodes — the points where the Moon’s orbit crosses the ecliptic, which is exactly where eclipses happen. That is why a tradition without telescopes still tracked them.
Why this system is stricter about your birth data
Stricter than Zi Wei, and the reason is the ascendant:
- Birth time to the minute matters. The ascendant moves by degree, so half an hour can push it into the next sign. Zi Wei uses two-hour periods and tolerates far more.
- Birthplace is required. The ascendant depends on latitude and longitude — the same clock time in two provinces can give different results.
If you only know an approximate hour, cast a few nearby times and check each against events already in your life.
