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.

Timeline
Each year shows the event, luck pillar, annual pillar, relations, and interpretation for direct comparison.
Early Recognition in the Prefectural Examinations
At age twenty, he placed among the top candidates in the annual examinations and was ranked fourteenth in the first tier, marking his early academic promise and official recognition.
This year was the Ren Shen annual year within the Ding Si Luck Pillar. Ren Water Proper Resource appears in the stem, a favorable element for the chart, indicating academic progress and recognition. The Shen Metal Officer combines with the Si Fire of the Luck Pillar (Si–Shen combination), while the stems Ding and Ren combine into Wood, forming a ‘Heaven-and-Earth double combination.’ This configuration favors exams and advancement. With Tianyi and Guoyin Nobleman stars present, support from authorities and mentors is clearly indicated.
Loss of Family Protection and Decline of Household Fortunes
The death of his grandfather Gu Shaofu removed the family’s main pillar, placing heavy responsibility on Gu Yanwu and marking the beginning of the family’s decline.
During the Bing Chen Hurting Officer Luck Pillar, the Geng Chen year brought heavy Earth energy. The Chen–Chen self-punishment and the Chou–Chen break damaged the Indirect Resource (Water) hidden in the Year Pillar, symbolizing the loss of elder protection and family foundation.
Entry into the Imperial Academy through Donation
He entered the Imperial Academy as a registered student through donation, gaining higher status and access to political and scholarly circles.
The Gui Wei year brought Gui Water Indirect Resource to the stem, a key favorable element for recognition and academic status. Combined with the Hurting Officer Luck Pillar, this supports advancement through unconventional means, such as donation, to secure official credentials.
Dynastic Collapse and Family Tragedy

The Yi You year repeats the Day Pillar, a classic sign of grief and family calamity. Clashes and punishments involving Metal and Wood intensified Seven Killings pressure, while favorable Water and Wood were suppressed. This configuration corresponds to extreme family loss and a decisive life turning point.
Advising the Southern Ming in a Time of Crisis
Recommended by the Kunshan magistrate, he served in the Southern Ming Ministry of War, authoring strategic essays known as the “Four Treatises of the Yi You Year,” and formally committed himself to national resistance.
At the transition from Bing Chen to Yi Mao Luck Pillars, Companion Wood strengthened the Day Master. Although Seven Killings pressure remained strong, the alignment of favorable elements allowed him to shoulder responsibility and contribute through strategy and writing.
A High-Risk Restoration Plot
He secretly participated in a failed plot to restore the Ming. After the plan collapsed and allies were killed, he narrowly escaped and went into hiding.
In the Yi Mao Luck Pillar, the Ding Hai year formed a Hai–Mao–Wei Wood combination, signaling alliances and shared purpose. However, intense clashes between Wood and Metal meant that despite support, the weak Day Master could not withstand Seven Killings pressure, leading to failure and flight.
Disguise and Flight to Avoid Assassination
Targeted for assassination, he cut his hair, changed clothes, adopted the alias Jiang Shan Yong, and lived disguised as a merchant while hiding across the Jiangnan region.
The Geng Yin year brought an Officer–Day Master combination that concealed danger rather than opportunity. Yin Wood provided a new root and identity, while movement stars indicated travel and concealment to preserve safety.
Imprisonment after Household Conflict
After executing a rebellious servant, he was falsely accused of murder and imprisoned. Friends intervened, and the case was eventually resolved.
The Yi Wei year intensified Earth Wealth energy, which generated Seven Killings Metal. Household and property matters triggered legal trouble, though Companion support from the Luck Pillar enabled eventual release.
Surviving an Assassination Attempt
After his release, assassins attacked him outside Taiping Gate in Nanjing. He narrowly survived with help from others.
The Bing Shen year clashed strongly with the Jia Yin Luck Pillar. Yin Wood Yang Blade was struck by Shen Metal Seven Killings, a classic sign of violent danger. Fire in the stem moderated the Metal somewhat, allowing survival.
Final Farewell to the Ming Tombs and Departure North
After repeated visits to the Ming imperial tombs, he sold his property, vowed never to return home, and began his long northern journey.
The Yin–Shen clash signaled major movement and relocation. Hurting Officer Fire drove decisive action, while Companion support gave him the resolve to abandon property and pursue a new path aligned with favorable elements.
Northern Travels and Field Investigation
He traveled as far as Shanhai Pass, conducting on-site studies of geography and defenses, integrating scholarship with firsthand investigation.
The Ji Hai year formed stem and branch combinations with the Luck Pillar, while strong Water Resource supported learning and travel, marking a productive phase of field-based scholarship.
Imprisonment in a Literary Inquisition Case
Implicated in a poetry-related case in Laizhou, Shandong, he was imprisoned again but ultimately rescued through friends’ efforts.
In the Gui Chou Luck Pillar, the Wu Shen year damaged Resource through Wealth, intensifying Officer and Seven Killings pressure. This reflects legal trouble tied to writings, mitigated by lingering Resource support from allies.
