茅以升
Mao Yisheng (1896–1989) was a pioneering Chinese structural engineer known as the father of modern Chinese bridge design. Trained in the U.S., he led landmark projects (Qiantang, Wuhan, Chongqing), advanced engineering education, and combined technical brilliance with civic ethics.
BaZi Chart
Birth Time Verification
Core Analysis
The natal chart centers on a 辛日主 (Xin metal Day Master) seated in 酉 with supporting metals in 申. This gives a naturally strong metal constitution in the 五行, indicating clarity of thought, structural insight and an aptitude for precise, technical work. The presence of 比肩 elements shows strong self-reliance and an independent professional temperament that favors leading technical teams and standing firm in decisions.
Earthly branches 丑 and 未 introduce 印 energy, supplying scholarly support, learning ability and methodical study—critical for academic breakthroughs like doctoral work and formulation of technical laws. The chart includes 官/杀 influences in key pillars, which manifest as a sense of responsibility, tolerance for risk, and readiness to assume public duty—consistent with his wartime actions and major state projects.
Major 大运 transitions align with life milestones: early 丁亥/丙戌 years correspond to foreign study and doctoral attainment; 乙酉/甲申 periods coincide with major bridge projects and wartime trials; later 壬午/辛巳 bring creative output and institutional leadership. Overall the 格局 combines technical genius (辛日主 + 比肩 + 印) with administrative authority (官/七杀) and resilience under pressure.
Traits
Engineering Acumen
Astrological basis: a robust 辛日主 reinforced by metal branches (酉, 申) and learning support from 印. 命理依据: this configuration produces clear, analytical thinking and structural intuition that explain his bridge design innovations.
Leadership & Responsibility
Astrological basis: presence of 正官/七杀 influences in month/hour and favorable 大运 during career peaks. 命理依据: 官/七杀 bring a sense of duty and tolerance for command, matching his roles overseeing major national projects.
Patriotism & Engineering Ethics
