BaZi turns the year, month, day, and hour you were born into eight characters (two each) — your chart — and reads how those characters support or control one another. It isn't a fortune-telling trick; it's closer to a language for reading your born nature and how your circumstances shift over time.
This track has 19 chapters. You'll start with the nature of the characters themselves — yin-yang and the Five Elements, then Heavenly Stems and Earthly Branches — before moving to hidden stems and the month's season, where you learn to measure real strength. From there you'll read the relationships between characters through the Ten Gods and family ties, set a chart's structure, and answer “so what energy do I actually need” through climatic balance and the favorable element. Last, you'll layer time itself on top with Luck Pillars and Annual Pillars.
Each chapter opens with the concept, then lets you check it straight against your own chart once you've entered your birth date — no sign-up needed, and it costs nothing to read.
