Concepts

  • Annual PillarThe yearly stem–branch layer stacked on the natal chart and luck cycle.
  • Day MasterThe day-pillar Heavenly Stem; the central reference for favorable/unfavorable judgments and Ten-God relations.
  • Four PillarsYear, month, day, and hour stem–branch pairs that form the skeleton of a BaZi chart.
  • Hidden StemsHeavenly Stems stored inside Earthly Branches; they affect rooting and the quality of revealed stems.
  • Luck CycleStaged luck stems and branches arranged forward or reverse from the month pillar, roughly one step per decade.
  • Na YinAn auxiliary Five-Element mapping attached to the sixty Jiazi pairs.
  • Ten GodsA system that classifies other Heavenly Stems into ten relational symbols from the Day Master by generation/control and yin/yang.
  • Useful GodWithin a given pattern, the Five-Element or Ten-God orientation most valuable for supporting, restraining, or climate-adjusting the Day Master—a working hypothesis in deduction.

Tables

Rules

  • Luck Cycle Forward/ReverseYear-stem yin/yang and sex determine whether luck cycles run forward or reverse, linked to starting-age calculation.
  • True Solar TimeCorrect clock time to local apparent solar time using longitude and the equation of time to reduce hour-pillar error.
  • Zi Hour Day ChangeRule split on whether early and late Zi hour belong to the day’s pillar, with decision steps and recording norms.

Methods

  • Chart Deduction and Reading OrderRecommended deduction order from four-pillar structure through Useful-God orientation to luck cycles and annual pillars, and the question each layer should answer.
  • Common BaZi Chart FieldsMeanings of chart and deduction fields, how they are produced, and how to use them when reading.
  • Deriving Luck CyclesDetermine luck-cycle forward/reverse from month pillar, year-stem yin/yang, and sex; compute starting age and decade handovers.
  • Deriving Ten GodsStepwise algorithm that maps other stems and branches to Ten Gods from the day stem by Five-Element generation/control and yin/yang sameness.
  • Four-Pillar Charting MethodFull steps from Gregorian birth moment to year, month, day, and hour pillars, plus common branch rules.
  • Ten-God Combinations and Luck TechniquesStructural readings of common Ten-God combinations, plus a checklist when stacking luck cycles and annual pillars.
