What is Chinese BaZi (Eight Characters) Astrology?

Introduction

BaZi (Eight Characters) astrology, also known as "Four Pillars of Destiny" or "Zi Ping Method," is a fundamental branch of traditional Chinese metaphysics. Based on one's birth time, it analyzes the relationship between Heavenly Stems and Earthly Branches to forecast personal destiny. As a significant component of Chinese culture, BaZi represents ancient Chinese observations of natural laws and serves as a reference tool for life guidance in modern society. This article systematically explores this ancient practice's concepts, terminology, origins, and development.

I. Understanding BaZi

BaZi's core principle revolves around constructing a "destiny chart" using four time units (year, month, day, and hour of birth), known as the "Four Pillars," each composed of a Heavenly Stem and an Earthly Branch.

Four Pillars: Each pillar consists of a Heavenly Stem and an Earthly Branch, representing birth year, month, day, and hour.
Eight Characters: The name comes from the eight components across the four pillars (e.g., Jia-Zi year, Yi-Chou month, Bing-Yin day, Ding-Mao hour).
Metaphysical Logic: Analysis focuses on the Five Elements (Metal, Wood, Water, Fire, Earth), their strength and interactions, and the Ten Gods system to interpret personality, health, career, and relationships.

II. Core Terminology

1. Heavenly Stems and Earthly Branches

Heavenly Stems: Ten components (Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, Gui) representing celestial energy cycles.
Earthly Branches: Twelve components corresponding to zodiac animals and directions.
Sexagenary Cycle: A 60-combination system formed by pairing Stems and Branches for time notation.

2. Five Elements Theory

The Five Elements form BaZi's theoretical foundation:

Generating Cycle: Metal → Water → Wood → Fire → Earth → Metal
Controlling Cycle: Metal → Wood → Earth → Water → Fire → Metal

3. Ten Gods System

A symbolic system describing relationships:

Direct Resource/Indirect Resource (Elements generating you)
Direct Wealth/Indirect Wealth (Elements you control)
Direct Officer/Seven Killings (Elements controlling you)
Friend/Rob Wealth (Same element as you)
Direct Print/Indirect Print (Elements generating your element)
