About Bazi
Bazi (八字), also known as the Four Pillars of Destiny, is a Chinese astrological system that uses your birth date and time to construct four pillars — each containing a Heavenly Stem and an Earthly Branch. The Day Master (日主), derived from your day of birth, represents your core self. The Ten Gods (十神) reveal how different energies manifest across career, wealth, relationships, and more. The balance of the Five Elements (五行) — Wood, Fire, Earth, Metal, and Water — determines your chart's strengths and favorable elements.
How to read your Bazi (Four Pillars) chart
Bazi maps your birth into four pillars of destiny. Here's how to get the most out of it in three steps.
Enter your birth details
Provide your birth date, time, and gender. Gender determines the direction of your 10-year luck cycles (Da Yun).
Identify your Day Master
The Day Master (the heavenly stem of your day pillar) represents your core self. Its strength (strong or weak) shapes how the five elements affect you.
Review your luck pillars
Each 10-year luck pillar interacts with your natal chart. Your current pillar reveals the dominant theme of this decade.
What the Day Master reveals about you
Your Day Master is the heavenly stem of your birth day — it is the most personal element in your chart. A strong Day Master needs output (wealth, power) to balance it; a weak one benefits from support (resource, companion). Understanding your Day Master's strength is the foundation of all Bazi analysis.
How the five elements balance
Bazi tracks five elements — Metal, Wood, Water, Fire, and Earth. Your chart has a distribution of these. A dominant element shapes your temperament; a missing or weak element shows where you may need to compensate. The favorable element (Yong Shen) is what brings your chart into balance.
Reading your luck pillars
Luck pillars (Da Yun) cycle every ten years, stacking a new energy on top of your natal chart. When a pillar's elements match your favorable element, that decade tends to flow; when they clash, it brings challenges. Knowing your current pillar helps you align timing with action.
Frequently Asked Questions
What is Bazi (Four Pillars of Destiny)?
Bazi is a Chinese destiny analysis system over a thousand years old. It constructs four pillars from your birth year, month, day, and hour, each with a Heavenly Stem and Earthly Branch, to reveal your personality, potential, and life cycles.
What is the Day Master in Bazi?
The Day Master is the Heavenly Stem of your day pillar. It represents your core identity and self in Bazi analysis. All other elements in your chart are interpreted in relation to the Day Master.
Why is gender needed for Bazi?
Gender determines the direction of your Decade Pillars (Da Yun / 大运) — the 10-year luck cycles. Males with Yang year stems and females with Yin year stems count forward; the reverse counts backward.
Can Bazi predict my future accurately?
Bazi maps the elemental balance and timing cycles of your life, not fixed events. It identifies favorable periods and potential challenges through decade pillars (Da Yun) and annual pillars. Classical practitioners treat it as a climate report for decision-making, not deterministic prediction. Outcomes depend on choices made within those tendencies.
What are the Five Elements in Bazi?
The Five Elements are Wood, Fire, Earth, Metal, and Water. Each appears in yin or yang form across your eight characters. Their balance determines your Day Master's strength and which elements favor you (yongshen). A chart with excessive Fire may need Water to cool it, while weak Metal may benefit from Earth to support it.
What are the Ten Gods in Bazi?
The Ten Gods (Shi Shen) are relationship patterns between your Day Master and other stems or branches in the chart. They include Companion, indirect/companion profiles representing self and peers, and roles like Direct Wealth, Indirect Wealth, Direct Officer, and Seven Killings. Each describes how career, relationships, and resources manifest in your life.
