BaZi 八字 — Four Pillars of Destiny AI reading

BaZi (八字) is the Chinese system of reading a person's life from the four pillars of their birth moment — year, month, day, and hour. Each pillar contributes a heavenly stem and an earthly branch, and the interactions among them reveal the Day Master's strength, the chart's pattern (格局), and the Useful God (用神) that shapes the reading.

Tian Qi's BaZi calculator runs the v2 methodology end-to-end: void-branch (空亡) detection by 旬, combination classification (化 / 合而不化 / 不化), 得令 / 得地 / 得势 scoring with multiplicative damage modifiers, 2-tier 身旺 / 身弱 verdict, strict-order pattern detection, and 用神 selection that consults the 120-cell 穷通宝鉴 lookup. The AI interprets the resulting verdict in Master Sean Chan's voice.
