Ba Zi Glossary 八字术语
A comprehensive reference of Four Pillars of Destiny terminology. Each term includes its Chinese characters, pinyin romanization, and a clear definition to help you understand your Ba Zi chart.
Core Concepts
- Ba Zi八字
- Literally "Eight Characters." Ba Zi is the foundational system of Chinese destiny analysis. It uses the year, month, day, and hour of birth to construct four pillars, each composed of a Heavenly Stem and an Earthly Branch — eight characters in total. Also known as the Four Pillars of Destiny (Si Zhu Ming Li), it reveals personality traits, life patterns, relationships, career tendencies, and future timing.
- Four Pillars四柱
- The four columns that make up a Ba Zi chart: the Year Pillar (representing ancestry and early childhood), the Month Pillar (representing parents and inner character), the Day Pillar (representing the self and spouse), and the Hour Pillar (representing children and later life). Each pillar consists of one Heavenly Stem on top and one Earthly Branch below.
- Day Master日主
- The Heavenly Stem of the Day Pillar. The Day Master is the single most important element in a Ba Zi chart — it represents the core identity, personality, and essential nature of the individual. All other elements in the chart are analyzed in relation to the Day Master to determine the Ten Gods, element balance, and overall chart strength.
- Heavenly Stems天干
- The ten celestial stems that cycle through Chinese calendrical calculations: Jia (甲), Yi (乙), Bing (丙), Ding (丁), Wu (戊), Ji (己), Geng (庚), Xin (辛), Ren (壬), and Gui (癸). Each stem carries an element (Wood, Fire, Earth, Metal, or Water) and a polarity (Yin or Yang). They appear as the top character in each pillar of a Ba Zi chart.
- Earthly Branches地支
- The twelve terrestrial branches that correspond to the twelve Chinese zodiac animals: Zi/Rat (子), Chou/Ox (丑), Yin/Tiger (寅), Mao/Rabbit (卯), Chen/Dragon (辰), Si/Snake (巳), Wu/Horse (午), Wei/Goat (未), Shen/Monkey (申), You/Rooster (酉), Xu/Dog (戌), Hai/Pig (亥). They form the bottom character of each pillar and contain hidden stems that add depth to chart analysis.
- Stem-Branch Cycle干支
- The sexagenary (60-year) cycle formed by pairing the 10 Heavenly Stems with the 12 Earthly Branches. Beginning with Jia-Zi (甲子) and ending with Gui-Hai (癸亥), this cycle produces 60 unique combinations that repeat throughout Chinese calendrical history. Each day, month, and year is assigned a stem-branch pair, forming the basis of all Ba Zi calculations.
Five Elements (Wu Xing)
The Five Elements (Wu Xing 五行) are the fundamental forces that govern all interactions in a Ba Zi chart. Each element has a generative (producing) relationship and a controlling (restricting) relationship with the others, creating a dynamic system of balance and tension.
- Wood木
- The element of growth, flexibility, and creativity. Wood represents upward movement, expansion, and the energy of spring. In personality, Wood is associated with kindness, vision, planning, and determination. Wood people tend to be innovative, compassionate, and driven to grow.
- Fire火
- The element of passion, warmth, and transformation. Fire represents radiance, illumination, and the energy of summer. In personality, Fire is associated with enthusiasm, charisma, expressiveness, and joy. Fire people tend to be warm-hearted, inspiring, and socially magnetic.
- Earth土
- The element of stability, nourishment, and grounding. Earth represents centering, reliability, and the transitional energy between seasons. In personality, Earth is associated with trustworthiness, patience, practicality, and nurturing. Earth people tend to be dependable, loyal, and methodical.
- Water水
- The element of wisdom, adaptability, and flow. Water represents downward movement, depth, and the energy of winter. In personality, Water is associated with intelligence, resourcefulness, introspection, and diplomacy. Water people tend to be perceptive, flexible, and philosophically minded.
- Generating Cycle相生
- The productive cycle in which each element nourishes the next: Wood feeds Fire, Fire creates Earth (ash), Earth bears Metal (ore), Metal enriches Water (minerals), and Water nurtures Wood. This cycle describes supportive, nurturing relationships between elements in a Ba Zi chart.
- Controlling Cycle相克
- The restrictive cycle in which each element restrains another: Wood parts Earth (roots), Earth dams Water, Water extinguishes Fire, Fire melts Metal, and Metal chops Wood. This cycle describes challenging or disciplining relationships between elements in a Ba Zi chart.
Yin & Yang
Yin and Yang are the two complementary polarities that pervade all of Chinese metaphysics. Every Heavenly Stem and Earthly Branch carries either a Yin or Yang quality, and the interplay between them is fundamental to chart interpretation.
- Yang陽
- The active, bright, and expansive polarity. Yang represents outward energy, assertiveness, initiative, and the dynamic aspect of nature. Yang stems and branches tend to express their elemental qualities in a bold, direct, and forceful manner.
- Yin陰
- The receptive, quiet, and inward polarity. Yin represents internal energy, subtlety, patience, and the reflective aspect of nature. Yin stems and branches tend to express their elemental qualities in a gentle, flexible, and refined manner.
Ten Gods (Shi Shen)
The Ten Gods (Shi Shen 十神) are the ten relational archetypes derived by comparing each element in the chart to the Day Master. They reveal how different energies interact with your core identity and influence your personality, relationships, career, and fortune.
- Friend比肩
- Same element as the Day Master, same polarity. The Friend star represents peers, equals, independence, self-reliance, and competition. A strong Friend presence indicates someone who values autonomy and has a strong sense of self-identity.

- Eating God食神
- Element produced by the Day Master, same polarity. The Eating God represents creativity, pleasure, artistic talent, and a relaxed demeanor. It indicates natural talent for expression, enjoyment of life, and the ability to produce and create with ease.
- Hurting Officer伤官
- Element produced by the Day Master, opposite polarity. The Hurting Officer represents unconventional thinking, rebellion, sharp intelligence, and outspokenness. It indicates a personality that challenges authority, pursues innovation, and has strong creative or intellectual abilities.
- Direct Wealth正财
- Element controlled by the Day Master, opposite polarity. Direct Wealth represents stable income, diligence, practicality, and financial management. It indicates a person who earns through consistent effort, values security, and manages resources carefully.

- Indirect Resource枭神
- Element that produces the Day Master, same polarity. The Indirect Resource represents unconventional wisdom, spiritual insight, solitary thinking, and specialized knowledge. It indicates an independent learner who acquires knowledge through experience and intuition rather than formal education.
Branch Relationships
Branch relationships describe how the twelve Earthly Branches interact when they appear together in a chart or in transit. These interactions — harmonies, clashes, harms, and punishments — significantly affect the dynamics of a Ba Zi reading and daily horoscope.
- Six Harmonies六合
- Six special pairings of Earthly Branches that bond together to produce a combined element: Rat-Ox (Earth), Tiger-Pig (Wood), Rabbit-Dog (Fire), Dragon-Rooster (Metal), Snake-Monkey (Water), and Horse-Goat (Fire). When two branches in a harmony pair appear in a chart, they create a cooperative, supportive energy that strengthens the resulting element.
- Three Harmonies三合
- Four triangular groupings of three Earthly Branches that unite to form a powerful elemental frame: Monkey-Rat-Dragon (Water), Tiger-Horse-Dog (Fire), Snake-Rooster-Ox (Metal), and Pig-Rabbit-Goat (Wood). When all three branches of a triangle appear in a chart, the elemental alliance is strong and highly influential.
- Six Clashes六冲
- Six pairs of directly opposing Earthly Branches: Rat-Horse, Ox-Goat, Tiger-Monkey, Rabbit-Rooster, Dragon-Dog, and Snake-Pig. Clashes bring disruption, conflict, movement, and change. In daily horoscope readings, clash days often signal turbulence that requires caution and flexibility.
- Six Harms六害
- Six pairings of Earthly Branches that create hidden friction and subtle sabotage: Rat-Goat, Ox-Horse, Tiger-Snake, Rabbit-Dragon, Monkey-Pig, and Rooster-Dog. Unlike the obvious conflict of clashes, harms operate beneath the surface, causing misunderstandings, betrayal, or gradual erosion of trust.
- Three Punishments三刑
- Disciplinary relationships among certain Earthly Branches that bring karmic lessons, legal issues, or health concerns. The ungrateful punishment involves Rat-Rabbit, the bullying punishment involves Tiger-Snake-Monkey, and the self-punishment involves Horse-Horse, Dragon-Dragon, Rooster-Rooster, or Pig-Pig.
- Destruction破
- A minor disruptive interaction between certain Earthly Branch pairs that weakens or undermines existing harmonies. Destruction is less severe than clashes or punishments but can introduce small setbacks, broken plans, or minor obstacles that require patience and adaptability.
Special Stars & Luck Pillars
Special stars (Shen Sha 神煞) are significant markers derived from the relationships within a Ba Zi chart. They highlight specific talents, fortunes, or warnings that add nuance to the basic element and pillar analysis.
- Peach Blossom桃花
- A star of romance, beauty, and personal charisma. When the Peach Blossom star is active in a chart or daily transit, it enhances attractiveness, social magnetism, and romantic encounters. It is derived from the Day Branch and indicates periods of heightened appeal and relationship potential.
- Noble Helper天乙贵人
- The most auspicious benefactor star in Ba Zi. When the Noble Helper appears in a chart or transit, it indicates the presence of helpful people, mentors, or fortunate encounters that ease difficulties and open doors. People with strong Noble Helper stars tend to receive timely assistance throughout their lives.
- Luck Pillars大运
- Ten-year fortune periods derived from the Month Pillar that map the broad energetic themes of each decade of life. Luck Pillars progress forward or backward through the stem-branch cycle depending on gender and the Year Stem's polarity, creating a unique timeline of favorable and challenging decades for each individual.
