Four Pillars and the Ten Heavenly Stems

The origins of Four Pillars and how to read it

Four Pillars developed from Chinese calendars and yin-yang and Five Elements thought. The birth day offers a starting point for considering the season and surrounding placements. Classical texts emphasize different conditions, so the reading states its perspective rather than reducing a person's character or future to one symbol.

This site revisits selected passages in Di Tian Sui, Zi Ping Zhen Quan and Qiong Tong Bao Jian. Di Tian Sui informs the observation of seasons and roots: same-element support within Branches. Zi Ping Zhen Quan informs the monthly baseline, exposed hidden Stems and Branch groupings. Qiong Tong Bao Jian informs differences in warmth, cold, dryness and moisture by month and Day Stem. These remain distinct perspectives, with observed conditions separated from questions not yet judged.

This site's method changes the year at the Beginning of Spring and months at solar terms such as Awakening of Insects and Pure Brightness. For a known birth time, Day and Hour Pillars use the birthplace clock converted to true solar time, with the date changing at midnight. If a solar-term boundary or clock change prevents one definite chart, alternatives and the supported reading scope are retained. Schools differ in time conversion and day boundaries, so results may differ from other sites or books.

The balance of the Five Elements

Wood, Fire, Earth, Metal and Water are five symbols for differences in nature and function. Their relationships include generation and control. Beyond quantities, the chart considers the season, hidden Stems within Branches, positions of support and relationships among the pairs. Reference counts are displayed separately from judgments that include season and support.

• Wood（Spring・Benevolence: consideration for others）：Growth, development and reaching outward: symbolic energy for planning and moving toward the future.
• Fire（Summer・Propriety: courtesy）：Passion, expression and brightness: symbolic energy that draws attention and warms an atmosphere.
• Earth（Doyo: seasonal transitions・Trustworthiness: sincerity）：Stability, trust and receptiveness: symbolic energy for nurturing and bringing things together.
• Metal（Autumn・Righteousness: fairness）：Decision, refinement and harvest: symbolic energy for releasing what is unnecessary and polishing value.
• Water（Winter・Wisdom: understanding）：Wisdom, flexibility and flow: symbolic energy for deep thought and adaptable responses.

The Ten Gods

The Ten Gods name ten element-and-polarity relationships between the Day Stem and other Stems. They are introduced as language for considering steps such as creating an idea, preparing conditions and handing work over. In an actual reading, birth month, roots, exposed positions and multiple candidates are considered together to establish the situation in which each symbol is being used.

• Peer（Self stars・Independence and identity）：A phrase for considering steps you choose and carry out yourself. Even in a shared task, distinguishing one decision of your own from one to entrust reveals the roles you bring.
• Competing Peer（Self stars・Competition and companions）：This reading concerns bringing strengths together and dividing roles. In a shared plan, first separate discussion matters from individual decisions in writing, making cooperation easier to describe.
• Expression (Shi Shen)（Expression stars・Enjoyment and everyday provisions）：Consider trying what you enjoy and arranging it sustainably. Let one person experience what you made and ask what they enjoyed, helping choose ideas to retain next time.
• Independent Expression（Expression stars・Perception and talent）：A perspective on expressing noticed differences through words or work. If many improvements appear, choose one thing to finish this time so your ideas can reach someone else.
• Indirect Wealth (resources)（Wealth stars: symbolic resources・Social connection and circulating resources）：Read this as connecting people or resources with those who need them. For a requested task, list available time, costs and responsibility to discuss the scope you want to accept.
• Direct Wealth (resources)（Wealth stars: symbolic resources・Steadiness and building reserves）：A perspective on arranging daily upkeep and promises sustainably. Reviewing monthly plans or expenses individually can help choose conditions you are comfortable retaining.
• Indirect Officer (responsibility)（Responsibility stars・Action and challenge）：When circumstances move, try one thing first and explore the response. In an urgent task, separating independent action from matters needing discussion makes later adjustment easier.
• Direct Officer (responsibility)（Responsibility stars・Discipline and recognition）：Read this as arranging accepted roles and promises in a form others understand. For a new responsibility, gather expected standards, deadline and contact together to check its scope.
• Indirect Resource（Resource stars: learning and support・Intuition and inspiration）：A perspective on stepping slightly away from a familiar method and trying another view. For an appealing idea, choose one possible use and a small trial to connect inspiration with the next question.
• Direct Resource（Resource stars: learning and support・Understanding and learning）：Consider receiving learning and experience and organizing them into a usable form. Explaining just one learned item to someone helps distinguish what you understand from what you want to ask again.
