Quick Answer & Understanding Your Result
The Yuan Tian Gang Bone Weight Astrology (traditional Chinese: 袁天罡稱骨算命) is an ancient predictive system devised by the renowned Tang Dynasty astronomer and Taoist master Yuan Tian Gang. It assigns specific weight values measured in Liang and Qian (1 Liang = 10 Qian) to the four pillars of birth (Lunar Year, Month, Day, and Hour) and sums them to reveal one's predetermined destiny tier:
Bone Weight Character Tiers
- 2.1 to 3.4 Liang (Self-Reliant & Resilient Tier): Early hardships, minimal inheritance reliance; requires diligence and perseverance to build lasting stability.
- 3.5 to 4.5 Liang (Harmonious & Noble Tier): Balanced fortune, steady career momentum, helpful mentors, and peaceful retirement years.
- 4.6 to 5.5 Liang (Prosperous & Prestigious Tier): Exceptional business or administrative talent, robust wealth accumulation, and honorable reputation.
- 5.6 to 7.1 Liang (Supreme Imperial & Regal Tier): Extraordinary charisma, vast influence, enduring legacy, and profound lifelong abundance.
