Chinese Astrology

Provide Chinese zodiac, BaZi, Zi Wei Dou Shu, Feng Shui, and Qi Men Dun Jia guidance with explicit inputs, assumptions, and uncertainty.

Scope and routing

• If the user wants Western astrology, route to Western resources (do not improvise).
• If the user wants Jyotish/Vedic, use ../project-astrology-vedic/SKILL.md.
• If the user wants Tarot or I Ching, use ../project-astrology-tarot-divination/SKILL.md.
• If the user wants numerology, use ../project-astrology-numerology/SKILL.md.

Core workflow

1. Collect inputs:
   • Birth date (Gregorian), birth time (local), birth place (city/country), timezone/DST at birth.
   • Zi Wei Dou Shu: also ask for sex at birth (some schools differ), and confirm lunar date conversion + leap month handling.
   • Feng Shui: building facing direction (degrees), period (move-in / last major renovation year), and the target room/sector.
   • Qi Men: the exact date/time (to the hour) and the question (goal, constraints, time horizon).
2. Choose the system based on the question:
   • Zodiac/compatibility: year animal + year stem element.
   • BaZi: Four Pillars, Day Master, Ten Gods, luck pillars.
   • Zi Wei: 12-palace chart + key stars + decade/year luck.
   • Feng Shui/Flying Stars: time + space sectors.
   • Ze Ri / timing: auspicious day/hour selection.
3. Apply accuracy rules (do not guess):
   • Zodiac animal year switches at Chinese New Year; Jan/Feb births must be checked.
   • BaZi year/month pillars use solar terms (Jie Qi); year pillar often switches near Li Chun (around Feb 4), not Chinese New Year.
   • Timezone/DST and birth location matter for hour pillar and solar term boundaries.
4. Produce the output:
   • State what was calculated (system, calendar basis, boundaries used).
   • If birth time is unknown, give a range or a partial reading and explain what changes with different hours.
   • Keep predictions non-deterministic; frame as tendencies and planning guidance, not guarantees.
5. Data handling:
   • Treat birth data as sensitive; do not store it and do not echo it back unnecessarily.

Common pitfalls

• Using Chinese New Year boundaries for BaZi pillars (BaZi uses Jie Qi solar terms).
• Assigning an animal year for Jan/Feb births without checking the Chinese New Year date.
• Treating a missing birth time as "close enough" for BaZi, Zi Wei, or Qi Men (it is not).
• Mixing schools without stating assumptions (for example, Zi Wei lunar conversion rules, Feng Shui period rules).
