Dai Zhen (1724–1777), a representative of Anhui scholarship in the Qing dynasty, was a linguist and master of textual criticism. He proposed a theory of nine categories and twenty-five divisions for ancient Chinese phonology. His writings were erudite, his intellectual character forthright, and he had many disciples, exerting a profound influence on later generations in the fields of exegesis and phonological studies.
BaZi Chart
Dai Zhen's BaZi (Ba Zi) chart shows a Day Master of Ji Earth, rooted in the primary qi of Si Fire beneath it. He favored Fire generating Earth, which manifested in his learning and analytical thinking. The Hour Pillar is Geng Wu, with the Geng stem revealing a Hurting Officer (Shang Guan). The Hurting Officer is the strongest symbol of literary talent and critical faculty—articulate, adept at questioning and correcting. The sharp edge and fierce criticism in his studies of the classics, phonology, and textual criticism are precisely the expression of this Hurting Officer temperament. When a Hurting Officer structure encounters Resource or Officer stars, it tends to bring setbacks in official careers and conflicts with established scholarly traditions. This explains why he repeatedly failed the metropolitan examinations in his youth, yet was specially summoned to the Hanlin Academy in his later years for his academic achievements, only to face criticism from his colleagues. This hour was chosen over one where a Resource or Direct Officer (Zheng Guan) stem appears because a prominent Resource star tends to indicate a reclusive and conventional nature, which cannot account for his sharp academic critiques; a prominent Direct Officer would mainly indicate a smooth official career, contradicting his history of repeated examination failures, late fame, and intense criticism of Confucian philosophy.
Core Analysis
With a Ji Day Master as its foundation, Dai Zhen's chart is supported by the Fire qi of Si. The Year Stem Gui and Month Stem Yi form the basis for his outward-looking analytical thinking and scholarly grounding. The overall chart presents an academic structure where the Hurting Officer is paired with the Resource star, and Fire generates Earth. The Hurting Officer governs sharp intellect and creativity, driving his originality in phonology, exegesis, and textual criticism. However, the Hurting Officer disposition easily invites friction and conflicts with colleagues, matching his fate of multiple examination failures before receiving an imperial appointment to the Hanlin Academy in his later years. In the progression of his Luck Pillars, the Geng Shen Hurting Officer Luck Pillar from 1768 to 1777 amplified his academic output while increasing controversy. The complex interaction between Resource and Eating God (Shi Shen) stars also indicates both academic support and fluctuations in fame and fortune.
Trait Analysis
- Depth of Knowledge: Rooted in the Ji Day Master and the Fire-Earth generating structure, he developed a solid foundation in the classics, history, and exegesis. The Hurting Officer in his chart brought academic creativity and meticulous textual-critical ability.
- Critical Independence: The combination of Hurting Officer and Resource star in his BaZi emphasizes intellectual tension and independent critique, showing his capacity to break through the Cheng-Zhu tradition and propose a humanistic philosophy based on human emotions.
- Educational Legacy: The support of Resource and Eating God stars in his later years allowed him to establish a stable sphere of academic and teaching influence, enabling disciples like Wang Niansun and Duan Yucai to inherit and develop his scholarship.
- Career and Controversy: While the Hurting Officer can bring academic success, it also easily invites friction. His BaZi and Luck Pillars show multiple obstacles in the examinations and frequent disputes with colleagues, requiring external patronage to achieve prominence.
Life Timeline
- 1734: At only ten years old, while reading Commentary on the Great Learning, Dai Zhen raised fundamental objections to Zhu Xi's annotations, displaying independent thinking and a critical spirit beyond his years. This year fell during the Jia Zi Luck Pillar and the Jia Yin Annual Pillar, with the double Jia Wood Direct Officer revealing in the stems. The Officer star represents rules, authority, and learning. The Annual Branch Yin Wood served as a strong root for the Officer star, and as the favorable adjustment element Jia Wood becoming rooted in the branches, it greatly enhanced the chart's much-needed regulating and constraining forces. The Ji Earth Day Master was strong, naturally indicating a tendency toward stubbornness, but the arrival of the Jia Wood Officer star to form a combination (Ji-Jia combination transforming into Earth) meant that he was not blindly rebellious. Instead, he examined and challenged existing rules (Zhu Xi's annotations) through a rational approach (the Officer star). At the same time, his chart carried the Hurting Officer Geng Metal and the Academic Hall symbolic star (Shen Sha) in the Hour Pillar. The Hurting Officer governs talent, questioning, and analytical thinking, while the Academic Hall governs intelligence and a love of learning. The combination of the two is the astrological root of his courage to challenge authority and display extraordinary analytical abilities. The strong Officer star in the Luck Pillar and Annual Pillar guided his abundant energy into deep exploration of orthodox scholarship rather than blind conformity.
- 1740: At eighteen, Dai Zhen accompanied his merchant father to Nanfeng in Jiangxi province, where he taught local schoolchildren, beginning his early teaching practice. This year, he was in the Gui Hai Indirect Wealth (Pian Cai) Luck Pillar. The Luck Pillar Stem Gui Water was a favorable Indirect Wealth element, representing the changes associated with traveling with his merchant father and living away from home. The Annual Branch Geng Shen revealed the Hurting Officer in the stems, representing the display of talent and teaching practice. Most crucially, the Annual Branch Shen combined with the Day Pillar Branch Si (Si-Shen combination transforming into Water), activating the Direct Resource star in the Day Branch. The Direct Resource represents knowledge, culture, and teaching; this combination activated the Resource star's power, perfectly corresponding to the event of "teaching schoolchildren." Meanwhile, the Water element was strong in both the Luck Pillar and Annual Pillar. The favorable Water element (Wealth star) was well-rooted, and since the Wealth star also represents the father, it showed the sign of "living away from home with his father." His career prospects were excellent this year, marking the starting point where his learning (Hurting Officer talent and Resource knowledge) was transformed into practice (teaching).
- 1742: In Shexian's Busu Garden, Dai Zhen met Jiang Yong, a great master of phonology. Although they had no formal master-disciple relationship, Dai was deeply influenced by Jiang's academic thought and research methods, laying a solid scholarly foundation for his future as a great erudite scholar. This year, the chart holder was in the Gui Hai Indirect Wealth Luck Pillar. The Luck Pillar Stem Gui Water was Indirect Wealth, and the Branch Hai Water was Direct Wealth (Zheng Cai). Together with the Month and Hour Pillars of the natal chart, they formed a Chou-Zi-Hai directional Water frame, bringing the Wealth star's power to its peak. The chart holder favored Wood and Water as his favorable elements, and this Luck Pillar was a time of extremely abundant favorable Water energy. The Annual Pillar was Ren Xu, with the Heavenly Stem Ren Water Direct Wealth revealing, which activated the Luck Pillar's Wealth star. Here, the Wealth star represents not only money but also opportunities and the display and absorption of talent. The natal chart itself featured an Indirect Wealth structure with a flowing sequence of Eating God and Hurting Officer generating Wealth, indicating intelligence, studiousness, and an aptitude for absorption. The Annual Pillar brought the Taiji symbolic star, denoting high comprehension and special insight into scholarship. Therefore, his ability to meet a great academic master like Jiang Yong and receive profound inspiration this year was a manifestation of the Wealth star (opportunities) and symbolic stars being activated in the Luck Pillar and Annual Pillar, along with the strength of his favorable elements. This opened a crucial door of enlightenment for his academic career.
- 1744: Dai Zhen completed the first volume of his mathematical work Ce Suan (Calculations), marking an important early achievement in his exploration of the natural sciences and demonstrating outstanding logical thinking and academic potential. This year featured the intersection of the Gui Hai Indirect Wealth Luck Pillar and the Jia Zi Annual Pillar. The Annual Stem Jia Wood Direct Officer revealed and combined with the Ji Earth Day Master, forming a structure where "the Officer comes to combine with the self," indicating that he was likely to receive official recognition and take on heavy responsibilities in his career—an excellent time for his talents to be put to use. Meanwhile, the Annual Branch Zi Water, the Month Pillar Branch Chou Earth, and the Luck Pillar Branch Hai Water formed a three-harmony Water frame. Water was the favorable Wealth star of the chart, and its energy reached its peak, representing that his thinking (Eating God and Hurting Officer generating Wealth) was as active as a flowing spring, with his logical and computational abilities greatly strengthened. The Luck Pillar Branch Hai Water was also the root of the favorable adjustment element Jia Wood, clarifying his mind and improving his focus. The convergence of multiple auspicious signs facilitated the birth of this early scientific work.
- 1746: Dai Zhen completed Illustrated Commentary on the Artificers' Record, combining ancient craft systems with mathematical knowledge and demonstrating his outstanding abilities in textual criticism and the study of names and artifacts, an important early result in his academic career. This year, Dai Zhen was in the middle of the Gui Hai Indirect Wealth Luck Pillar (1738–1747). The Luck Pillar Stem Gui Water was the favorable Indirect Wealth element, and the Branch Hai Water formed a three-harmony Water frame with the Month and Hour Pillars of the natal chart. The Wealth star's energy was extremely strong, representing active thinking and the ability to transform acquired knowledge into valuable results. The Annual Pillar was Bing Yin. The Heavenly Stem Bing Fire was the favorable adjustment element Direct Resource revealing, representing knowledge, reputation, and official recognition; the Earthly Branch Yin Wood was the favorable Direct Officer, and it combined with the Luck Pillar Branch Hai Water to form Wood, strengthening the Officer star's power and implying self-discipline, a sense of responsibility, and career opportunities. The Annual Pillar activated the Luck Pillar's Wealth and Officer stars, forming a flowing sequence of "Wealth, Officer, and Resource." This was precisely the time when personal talent (Hurting Officer) was transformed through rigorous research (Direct Resource) into academic achievements (Wealth star) recognized by officials or the scholarly community. The completion of Illustrated Commentary on the Artificers' Record was the perfect embodiment of the combination of talent, knowledge, and opportunity under this astrological structure.
- 1754: Because local tyrants within his clan encroached on his ancestral graves and he was falsely accused, Dai Zhen was forced to flee his hometown for Beijing, temporarily staying at the Shexian Guild Hall. In this time of difficulty, he had the good fortune to meet Qian Daxin, who later became a great scholar. Praised as a "rare genius of the world," Dai Zhen's life trajectory changed from this point. This year he was in the Ren Xu Direct Wealth Luck Pillar, with the Annual Pillar of Jia Xu. Astrologically, the Luck Pillar Stem Ren Water Direct Wealth revealed as a favorable element, representing the beginning of his life goals and values becoming apparent. However, the Branch Xu Earth Rob Wealth (Jie Cai) was an unfavorable element, forming a Chou-Xu punishment with the Month Pillar Branch Chou Earth. This punishment activated the Friend and Seven Killings (Qi Sha) stars in the Month Pillar, directly triggering fierce internal clan conflicts (Friend) and the pressure of legal troubles (Seven Killings), which was the astrological root of his flight from home. Nevertheless, the Annual Stem Jia Wood Direct Officer combined with the Ji Earth Day Master (Ji-Jia combination). The Officer star was a favorable element that came to combine with him, indicating that amidst the turbulence, he would instead meet the appreciation and patronage of noble helpers (officials and authoritative figures). At the same time, the Taiji symbolic star appeared in both the Luck Pillar and the Annual Pillar, signifying the opening of wisdom and the likelihood of receiving guidance from accomplished masters. Therefore, although he was forced from his home by the activation of unfavorable elements through punishment, the combination of the favorable Officer star with his Day Master and the support of symbolic stars allowed him to meet Qian Daxin in the capital and bring his talents to light. It was truly a case of "blessing in disguise" that opened a new chapter in his life.
- 1755: Dai Zhen first met Ji Yun (Ji Xiaolan) in the capital, and they hit it off immediately. Thereafter, whenever Dai Zhen visited Beijing, he stayed at Ji Yun's residence. The two refined each other's scholarship, and their friendship grew increasingly deep, making them lifelong close friends and academic confidants. This year marked the intersection of the Ren Xu Direct Wealth Luck Pillar and the Yi Hai Annual Pillar. The Annual Stem Yi Wood Seven Killings revealed, representing boldness, opportunities, and authoritative figures—fitting for his meeting with Ji Yun, a future leader of the literary world. The Annual Branch Hai Water formed a three-harmony Water frame with the Month Branch Chou and Hour Branch Zi of the natal chart. Water was the favorable Wealth star, governing movement, social interaction, and wisdom. The Hai Water also served as a Traveling Horse symbolic star, prompting travel and long journeys, matching the sign of going to the capital. Crucially, the Annual Branch Hai Water clashed with the Day Branch Si Fire (the Spouse Palace). This clash was a favorable element clashing with an unfavorable element; although it signified change, it often brought positive breakthroughs, breaking the original structure and activating noble helpers. Dai Zhen's chart possessed multiple symbolic stars, including Heavenly Yi, Wen Chang, and Taiji. This year also brought Heavenly Virtue combination and Monthly Virtue combination, resulting in extremely strong noble-helper fortune. His encounter with Ji Yun was exactly a case of noble helpers leading the way, opening up important networks and a stage for his academic career.
- 1756: At the invitation of Wang Anguo, the Minister of Rites, Dai Zhen served as a resident tutor in Wang's mansion, teaching the classics to his son, Wang Niansun. Wang Niansun later became a representative figure of the Qian-Jia school and a famous phonologist. This master-disciple relationship became a much-told tale in academia. This year featured the intersection of the Ren Xu Direct Wealth Luck Pillar and the Bing Zi Direct Resource Annual Pillar. The Annual Stem Bing Fire Direct Resource revealed; the Direct Resource represents elders, reputation, knowledge, and stable employment, aligning perfectly with the event of "taking a teaching position." Bing Fire was also the favorable adjustment element, bringing warmth and opportunities that allowed his knowledge to be appreciated. The Luck Pillar Stem Ren Water Direct Wealth clashed with the Annual Stem Bing Fire Direct Resource, forming a "Wealth-Resource clash," signifying changes in the career environment. However, this clash also activated the Resource star, facilitating this teaching position from an official's family (the Wealth star can represent the employer). The Annual Branch Zi Water was Indirect Wealth, a favorable element in his BaZi, and it combined with the Month Pillar Branch Chou Earth, activating the Wealth star and symbolic stars, representing the acquisition of practical benefits and elevation in status through professional skills (Eating God and Hurting Officer generating Wealth). The Annual Pillar's symbolic stars revealed the Heavenly Yi noble helper, indicating patronage from a noble helper (Wang Anguo). Overall, this was a year when favorable elements arrived and the Resource star exerted its power. His profound learning (the natal chart's inherent literary stars such as Wen Chang, Academic Hall, and Ci Guan) could be put to use on the platform provided by his noble helper, opening an important new chapter in his professional career.
- 1757: At the office of Lu Wenchao, the Salt Distribution Commissioner of the Two Huai regions in Yangzhou, Dai Zhen met Hui Dong, the master of the Wu school of classical studies. This meeting greatly expanded his academic horizons and promoted scholarly exchange and intellectual collision between the Anhui and Wu schools. This year was the last year of the Ren Xu Luck Pillar. The Luck Pillar Stem Ren Water Direct Wealth combined with the Annual Stem Ding Fire Indirect Resource, transforming into Wood qi. Wood represents the Officer and Killings for the Ji Earth Day Master, signifying reputation, career, and noble helpers. This combination activated the Seven Killings in the natal chart, indicating the encounter with an authoritative figure or major opportunity that would bring far-reaching influence to his career. The Annual Branch Chou Earth formed a fu yin (repetition) with the Month Pillar Branch Chou Earth, and was also in a punishment with the Luck Pillar Branch Xu Earth. Earth is the unfavorable Friend and Rob Wealth element; this punishment stirred his inner self, signifying changes in his environment and an inner quest that prompted him to step out of his original circle. The symbolic stars Taiji and Hua Gai appeared together in the Annual Pillar. Hua Gai governs academics, art, and solitary reflection, perfectly matching the encounter with an academic titan and the deep pursuit of classical studies. The Luck Pillar and Annual Pillar combining with the Wealth star also hinted that this trip to Yangzhou might have been related to a secretarial position (source of income) in a patron's establishment, providing a platform for his academic exchanges.
- 1764: After multiple disappointments in the imperial examinations, Dai Zhen finally passed the provincial examination this year. It was his only success in the examination system, representing an important breakthrough in his life. This year, the chart holder was in the Xin You Eating God Luck Pillar. The Luck Pillar formed a Si-You-Chou three-harmony Metal frame with the Month and Day Pillars, making the Eating God and Hurting Officer energy extremely strong and conducive to displaying talent and knowledge. The Annual Pillar was Jia Shen, with the Heavenly Stem Jia Wood Direct Officer revealing as a favorable element, representing official recognition and an opportunity for academic degree. Most crucially, the Annual Pillar and the Day Pillar Ji Si formed a "double combination of heaven and earth" (Jia-Ji combination transforming into Earth, and Si-Shen combination transforming into Water). This was a rare auspicious omen, signifying internal and external harmony, and receiving abundant help. The Si-Shen combination transforming into Water activated the Wealth star, and the mutual generation of Wealth and Officer successfully transformed his personal talent (Eating God and Hurting Officer) into academic recognition (Officer star), exactly corresponding to the sign of passing the provincial examination. The appearance of the National Seal and Heavenly Yi symbolic stars in the Annual Pillar further strengthened his fortune for official recognition and noble-helper patronage.
- 1765: Beginning in the thirtieth year of the Qianlong reign (1765), Dai Zhen began systematically collating Li Daoyuan's Commentary on the Water Classic from the Northern Wei dynasty. He resolved to fill in gaps and delete fallacies, restoring the text to its original source, thus launching a monumental ten-year scholarly collation project. This year, the chart holder was 42 years old and in the Xin You Eating God Luck Pillar. The Eating God governs technical skills, research, and the display of talent, perfectly aligning with the meticulous work of collating ancient texts. The Annual Pillar was Yi You, forming a Si-You-Chou three-harmony Metal frame with the Month and Day Pillars. Metal represents the chart holder's Eating God and Hurting Officer, governing thinking, expression, and academic ability; this frame greatly enhanced his capacity for textual criticism and analysis. The Annual Branch You Metal clashed with the Year Pillar Branch Mao Wood (Seven Killings), constituting a "clash with the Grand Duke (Tai Sui)," signifying change and breaking with the old to establish the new—exactly matching his academic innovation of challenging tradition, correcting errors, and filling gaps. At the same time, the Wen Chang noble helper appeared in both the Annual Pillar and the Luck Pillar, making it an excellent time for in-depth research and text-based work. The natal chart had a strong Day Master, favoring Wood (Officer and Killings) and Water (Wealth). The Annual Stem revealed Yi Wood Seven Killings; although it was clashed by the Luck Pillar's Xin Metal, the Wood qi could still loosen the Earth, allowing the chart holder to find direction amidst pressure and challenges (Seven Killings) and devote his energy to rigorous academic research.
