Core Analysis
Gu Yanwu’s chart centers on an 乙 daymaster surrounded by strong metal and earth influences. The duplicated 酉 (hour and day) and the presence of 己未 / 癸丑 create a compact picture: a persistent intellectual will facing continual external challenge. This overall 格局 reads as a scholar with deep inner principle and recurrent confrontation with authority.
From the perspective of 五行 and 十神, his chart shows active 比肩 energy (two 乙) supporting self-reliance, while the apparent 七杀/辛金 pressure from 酉 acts as catalytic adversity that forces manifestation of talent into action. The chart’s mix of 偏印 and 食神/伤官 themes signals a mind oriented to study, textual proof, and practical application rather than abstract theorizing.
Examining his 大运, early runs of 戊午 and 丁巳 align with youthful achievement (exam success,秀才), while the mid-life cycles 丙辰→乙卯→甲寅 correspond to political engagement, hardship, and eventual retreat into practical fieldwork. Later 癸丑→壬子 years reinforce the scholarly, reflective mode that produced his major works and public maxims.
In synthesis, the Bazi explains key life themes: principled resistance to compromise, rigorous empirical scholarship, endurance through persecution, and a lifelong turn toward practical, public-minded writing. The chart’s dynamics make clear why Gu Yanwu persisted as a moral exemplar and intellectual reformer.
Traits

High score justified by the chart’s 食神/伤官 and 偏印 configuration which supports practical study and evidence-based inquiry; Bazi shows a mind oriented to verification and textual critique.
Principled Integrity
Strong 比肩 and resistant 七杀 pressure produce a firm personal stance; the natal 格局 explains his refusal to serve an alien dynasty and insistence on moral responsibility.
Resilience under Adversity
Repeated cycles where 七杀 and earth energies clash with the 乙 daymaster account for sustained hardship and survival instinct, matching historical imprisonment, exile, and relentless travel.
Public Influence
Combination of expressive 伤官/食神 and authoritative life story created lasting influence; the 大运 transitions enabled output of major works and cultivation of followers.
