BaZi — The Four Pillars of Destiny
Chinese calendars label every year, month, day and hour with a pair of symbols: one of ten Heavenly Stems and one of twelve Earthly Branches. Your birth moment therefore has four pairs — eight characters. Traditionally the year pillar speaks of ancestry and roots, the month of parents and career, the day of yourself and your spouse, the hour of children and later life. It is, in essence, a Chinese natal chart.
The Day Master — the "you" in the chart
The Heavenly Stem of your day pillar is called the Day Master — it represents you. Everything else in the chart is read by how it supports, drains, or challenges your Day Master. Each Day Master is one of the Five Elements in yin or yang form: a "Yang Wood" person is a tall tree — upright, principled; a "Yin Water" person is morning dew — gentle, intuitive.
The Five Elements (Wu Xing)
Wood, Fire, Earth, Metal, Water — not substances but five phases of energy. They feed each other in a circle (Wood feeds Fire, Fire creates Earth/ash, Earth bears Metal, Metal collects Water, Water grows Wood) and control each other in another (Wood breaks Earth, Earth dams Water, Water quenches Fire, Fire melts Metal, Metal chops Wood). A "good" chart is not one with lucky symbols but one in balance.
Tai Sui — the God of the Year
Ancient astronomers tracked Jupiter's ~12-year cycle and personified each year's ruling energy as Tai Sui, the "Grand Duke of the Year" — imagine a celestial governor on annual rotation. When your birth sign clashes with the current year's sign, you are said to "offend Tai Sui": a turbulent, changeful year. Chinese people wear red for protection. We check this for you in the Destiny Report.
Symbolic Stars: Peach Blossom & more
Certain symbol combinations in a chart are named after vivid images. Peach Blossom (romantic charm — in old poetry, peach blossoms meant spring flirtation and admirers) marks natural attractiveness. Post Horse (from imperial relay-station horses) marks a life of travel and relocation. Canopy Star (the emperor's ceremonial parasol) marks solitary brilliance — artists and scholars. These "stars" are chart patterns, not actual celestial bodies.
The I Ching — Book of Changes
A 3,000-year-old oracle built from a binary alphabet: solid yang lines and broken yin lines, stacked six at a time into 64 hexagrams — every possible configuration of change. You consult it with a genuine question; the coin toss "samples" the moment, and the resulting hexagram is read as a mirror of your situation. Confucius annotated it; Jung wrote a famous foreword to it; Leibniz saw binary arithmetic in it.
The 12 Zodiac Animals
Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig — one per year in a 12-year cycle, each paired with an Earthly Branch. Your animal is the branch of your year pillar. Remember: the year flips at the Start of Spring (~Feb 4), not on New Year's Day — January-born readers are often one animal off!
The Ten Gods — chart roles
Despite the dramatic name, the "Ten Gods" are simply the ten roles another element can play relative to your Day Master — resource, output, wealth, authority, peer — each in yin/yang flavor. They translate abstract element math into life language: career style, money style, relationship style. Your dominant "god" defines your chart pattern.

1. Nature of the Service — Entertainment Only
Everything on XuanJi Pavilion — the BaZi chart, destiny reports, I Ching readings, horoscopes, and any AI-generated interpretation (together, the "Service") — is automatically generated from the symbolic systems of traditional Chinese metaphysics and Western astrology. It is offered strictly as entertainment and cultural exploration.

- Medical or mental-health advice. No reading is a diagnosis or treatment guidance. For any physical or psychological concern, see a qualified clinician promptly.
- Marriage, family, or major relationship decisions. Readings are not counseling. Decisions like marriage, divorce, or having children deserve real conversations and, where helpful, licensed professional support.
- Legal advice. For any legal matter, consult a licensed attorney.
- Matters of life, death, serious illness, or disaster. The Service will not answer or predict questions of this kind — please do not ask them. If you are in emotional distress, contact a local crisis helpline or a mental-health professional.
