CASE DETAIL

Gu Yanwu (顾炎武)

Gu Yanwu (1613–1682), style name Ningren, sobriquet Tinglin, was a late-Ming and early-Qing thinker and scholar. He championed practical learning for real-world governance and authored works such as Records of Daily Knowledge and Treatises on the Strengths and Weaknesses of the Regions. He is remembered for the maxim, “The rise and fall of the realm concerns every person.”

Birth Time Verification

There is no reliable public record of Gu Yanwu’s exact birth time. As an Yi Wood Day Master born in the You (Rooster) month, Wood is inherently weak and under strong Metal pressure. Only a chart with strong Companion Stars (Bi Jian) can explain sustained inner strength. The chart shows both the Day Branch and Hour Branch as Yi You, creating duplicated Companion energy. This pattern reflects a personality that is resolute, independent, and uncompromising—someone who upholds loyalty and principle and refuses to submit to external authority. This structure aligns closely with his lifelong refusal to serve the Qing, his solitary moral stance, extensive travel and investigation, and repeated experiences of imprisonment, assassination attempts, and exile. A time with heavier Resource would overemphasize academic protection, while Food God or Hurting Officer hours would suggest a more outward, flexible temperament. The 18:00 You hour best fits both character and life events.

Core Analysis

Gu Yanwu’s BaZi chart is Gui Chou , Ji Wei , Yi You , Yi You . The Day Master is Yi Wood, born in the autumn You Metal season, where Metal is strong and Wood is weak. This creates a structure of Wood being controlled by Metal. However, the Year Stem Gui Water provides Indirect Resource support, and the Hour Stem brings Companion strength, indicating self-reliance and a solid scholarly foundation.

Multiple Metal components generate strong Seven Killings pressure. In certain Luck Pillars—such as Ding Si and Bing Chen—the presence of Food God and Hurting Officer activates expression, critique, and writing. The Luck Pillar sequence is clear: Bing Chen (1636–1645) corresponds to turbulence, resistance to the Qing, exile, and political clashes; Gui Chou (1666–1675) and Ren Zi (1676–1685) are Resource-focused periods that favor textual research and major writings, consolidating his academic legacy.

Overall, the chart’s main thread is Indirect Resource supporting learning, Hurting Officer producing expression, and Seven Killings forging resolve. His temperament is upright and unyielding, with scholarship aimed at practical governance. At the same time, this structure brings repeated encounters with imprisonment, assassination attempts, family loss, and physical strain.
