From the Shang Dynasty
The origins of this tradition trace back to the Shang Dynasty (around 1300 BCE).
Stem-branch characters inscribed on oracle bones were used to record months and days. Records indicate that members of the Shang royal lineage incorporated the Heavenly Stem of their birthday into their names.
Tang Dynasty — The Founding Systematization
During the Tang Dynasty (618-907 CE), Li Xuzhong (李虚中) established for the first time the system of inferring destiny from the three pillars of birth.
Song Dynasty — The Zi Ping Revolution
In the Song Dynasty (960-1279), Xu Ziping (徐子平) developed the revolutionary theory of placing the Day Master at the center of chart reading. This became the foundation of all subsequent destiny analysis. The system bears his name: Zi Ping Method (子平術).
Ming Dynasty — The Golden Age
The Ming Dynasty (1368-1644) was the golden age of destiny analysis. Di Tian Sui (滴天髓), attributed to the state-founding strategist Liu Bowen (劉基, 1311-1375), was compiled. Liu Bowen was the chief strategist who helped Zhu Yuanzhang unify China and establish the Ming Dynasty — the preeminent political mind of his era.
The same era produced San Ming Tong Hui (三命通会) by Wan Yuwu (万育吾), and Qiong Tong Bao Jian (窮通宝鑑), compiled by Yu Chuntai (余春台), on seasonal adjustment.
Qing Dynasty — The Systematization's Completion
In the Qing Dynasty (1644-1912), the jinshi scholar Shen Xiaozhan (沈孝瞻) wrote Zi Ping Zhen Quan. The early Qing Minister of Rites Chen Suan (陳素庵) left the evaluation of Di Tian Sui quoted earlier.
Arrival in Japan
Japanese Sanmeigaku (算命学) took its systematic form in the early Showa era through the work of Takao Yoshimasa (高尾義政, 1917-1996), who reorganized Chinese classical destiny studies into a distinctively Japanese interpretive system.
Takao's Sanmeigaku established — on the foundations of the sexagenary calendar and Yin-Yang Five Elements theory — unique frameworks including Phase Methods (位相法), Void Periods (天中殺), and the Ten Major Stars (十大主星). From this foundation, many schools branched out, and a distinctive Japanese Sanmei culture developed.
The Position of Bazen Sanmei
Kings, ministers, and military strategists read their own charts and the directions of their states using this system. It was not mere fortune-telling. It was the philosophy of statecraft.
Bazen Sanmei inherits this three-thousand-year lineage while responding to the recent drift toward "fortune-telling" by advocating a return to the classical sources.
Drawing fully on the depth of the Chinese classics (Di Tian Sui, Zi Ping Zhen Quan, San Ming Tong Hui, Qiong Tong Bao Jian) and preserving the interpretive frameworks of Takao Sanmei (Phase Methods, Void Periods, etc.), Bazen Sanmei refrains from "fortune judgments" and "prescriptions for action," instead structuring the tradition as a system of self-understanding.
Bazen Sanmei is a contemporary school that transcends the boundaries between BaZi and Sanmei — drawing from both lineages, referenceable as a shared body of wisdom.
