Why No Chart Is Published
Two birth-date records
The Guofu Nianpu in the National Dr Sun Yat-sen Memorial Hall's scholarly database preserves a conflict. A genealogy gives the sixth day of the tenth lunar month, mapped there to 12 November 1866. Sun's handwritten autobiography gives the sixteenth day, mapped to 22 November. The 12 November birthday was publicly established only after his death and family inquiries. A later-discovered birth-chart artifact among Lu Muzhen's effects gives the sixth day at yin hour, but it does not eliminate the autobiographical conflict. This page therefore displays only 1866 and withdraws the old 03:00 value.
Confirmed biographical scope
The Memorial Hall sources support Cuiheng village as Sun's birthplace, his Western-style education and medical work, the founding of the Revive China Society in 1894, his revolutionary activity, his service as provisional president in 1912, and his death in Beijing in 1925. These facts do not establish a chart.
Why no chart is published
The current BaZi engine's solar-term data cannot compute 1866, and the exact birth date remains disputed. This page publishes no Pillars, stems and branches, Day Master, pattern, strength, Ten Gods, auxiliary stars, luck cycles, or annual-cycle conclusions. It does not infer a chart from political events. For supported dates, use the free BaZi chart. Traditional BaZi is a symbolic interpretive framework and is not health, financial, or legal advice.
