Why BaZi Works
“BaZi distills your birth moment into a framework more specific than Western astrology — personality, career rhythm, and relationship dynamics, all from four pillars.”
On the depth of BaZi
“The Life Landscape maps decade-long cycles of fortune. Understanding your current 大运 phase can reframe the past and sharpen decisions ahead.”
On Major Luck Cycles
“True Solar Time corrects for the gap between clock time and actual solar position at your birthplace — a difference that can shift your entire Hour Pillar.”
On precision
A Real Master.
Real Tradition.
Longchang isn’t a Silicon Valley simulation of Eastern wisdom — it is built by a practicing BaZi master and Feng Shui consultant who has studied the classical texts, consulted for real clients, and now channels a living tradition dating to the Tang and Song dynasties through modern computation.

Frequently Asked
What is BaZi?
BaZi (八字) is a Chinese metaphysical tradition with roots in the Tang dynasty (circa 900 CE), using your exact birth time to create a unique Four Pillars chart — mapping personality, trajectory, and timing.
What is True Solar Time?
True Solar Time (真太阳时) adjusts for the difference between clock time and actual solar position at your birthplace. This ensures your Hour Pillar is accurate — critical for a correct chart.
What is the Life Landscape?
The Life Landscape visualizes your BaZi fortune cycles — 10-year periods mapping the peaks, valleys, and turning points of your entire life.
What are the Ten Heavenly Stems?
The 十天干 are ten cosmic archetypes that form the backbone of BaZi. Your Day Master — the stem of your birth day — defines your core nature.
