Ri Yue Bing Ming Pattern: Tai Yang, Tai Yin, Light, and Balance
Ri Yue Bing Ming is a Zi Wei Dou Shu pattern built from Tai Yang and Tai Yin, the Sun and Moon stars. When both lights are strong and mutually connected, the chart gains clarity, openness, reputation, benefactor support, and the ability to balance action with accumulation.
The Sun and Moon are both bright stars, but their light works differently. Tai Yang shines outward: career, service, visibility, father, husband, son, and public responsibility. Tai Yin gathers inward: wealth, property, mother, wife, daughter, family, enjoyment, and preservation. A good Sun-Moon structure is not merely "bright." It must be strong, balanced, and supported by the whole chart.
This guide explains Ri Yue Bing Ming, Ri Zhao Lei Men, Yue Lang Tian Men, Sun-Moon same palace, Ri Yue Fan Bei, and related Sun-Moon patterns.
Tai Yang and Tai Yin: Core Nature
Tai Yang
| Item | Meaning |
|---|---|
| Element | Yang Fire |
| Status | Central major star |
| Role | Career lord, noble star, public-service star |
| Transformation qi | Nobility |
| Family symbolism | Father in male charts, husband in female charts, also son |
| Keywords | Yang, quick, active, competitive, service, reputation, bright and open |
Tai Yang emits light and heat. It illuminates others and often carries a public, service-oriented, or leadership meaning. Strong Tai Yang favors exposure, contribution, reputation, and outward action. It tends to rise earlier than Tai Yin.
Because Tai Yang is a noble star, when it sits in a kinship palace and meets heavy malefics, the theme of separation or harm can appear more clearly, especially involving male relatives or eye and heart health.
Tai Yin
| Item | Meaning |
|---|---|
| Element | Yin Water |
| Status | Central major star |
| Role | Property lord, wealth star, mother star, wife star |
| Transformation qi | Wealth |
| Family symbolism | Wife in male charts, mother and feminine qualities in female charts, also daughter |
| Keywords | Yin, reserved, gentle, slow, late development, wealth, family, enjoyment |
Tai Yin is inward light. It governs accumulation, protection, property, savings, family care, and refined enjoyment. It develops more slowly than Tai Yang and often becomes better in later life or later phases of a cycle.
Tai Yin's harshness, when damaged, often appears through female relatives, money, property, mood, or family matters.
The Bright-Star Principle
Tai Yang and Tai Yin are both bright and open stars. When strong, they tend to be upright, generous, and impartial. When supported by auspicious stars, action brings achievement. When damaged by harsh stars, the same action can become toil, wandering, or repeated effort without enough result.
Brightness is therefore central. A Sun-Moon pattern cannot be judged by star names alone.
Brightness Rules
Tai Yang Brightness
| Palace range | Tai Yang condition |
|---|---|
| Mao, Chen, Si, Wu | Strong, from sunrise to noon |
| Yin, Wei | Moderate |
| Shen, You, Xu, Hai, Zi, Chou | Fallen or weak |
Birth time also matters. Day birth supports Tai Yang. Night birth reduces its effect and can add toil even if the palace position is strong.
Tai Yin Brightness
| Palace range | Tai Yin condition |
|---|---|
| You, Xu, Hai, Zi, Chou, Yin | Strong |
| Shen, Chou, Wei | Mixed or moderate depending on structure |
| Mao, Chen, Si, Wu, Wei | Fallen or weak |
Tai Yin is judged by three layers:
- Palace brightness first.
- Birth time second: night birth helps; day birth discounts.
- Moon phase third: near the fifteenth lunar day is strongest; waxing is better than waning.
The Five Major Sun-Moon Patterns
1. Ri Yue Bing Ming
Ri Yue Bing Ming means the Sun and Moon are both bright. Tai Yang and Tai Yin occupy strong positions and meet through San Fang Si Zheng.
| Condition | Meaning |
|---|---|
| Tai Yang strong | Usually in Mao, Chen, Si, or Wu |
| Tai Yin strong | Usually in You, Xu, Hai, or Zi |
| Mutual connection | The two lights meet through San Fang Si Zheng |
| Support | Auspicious stars strengthen reputation, wealth, and benefactors |
A common example is Tian Liang in Chou as the Life Palace, with strong Sun and Moon in Si and You shining into the structure.
Typical traits:
- Open and upright temperament.
- Good benefactor support.
- Clear future direction.
- Reputation and social trust.
- Potential for both fame and wealth.
- Deep blessing when the whole chart cooperates.
If the year stem creates Tai Yang Hua Ji in Si and it clashes the structure, the pattern's brightness is reduced. This is why Four Transformations must always be checked.
2. Ri Zhao Lei Men
Ri Zhao Lei Men refers to Tai Yang in Mao, like the Sun rising at the eastern gate. This is one of Tai Yang's strongest positions.
Tai Yang in Mao often pairs with Tian Liang. The Career Palace in Wei may be empty and borrow the opposite Chou palace, where Ju Men and Tian Tong can participate.
Traits:
- Direct, bright, and public.
- Strong influence and service spirit.
- Values reputation and moral standing.
- Good for public work, education, law, service, leadership, and visible professional roles.
- With Tian Liang, intelligence and principle become stronger.
When Tai Yang, Tian Liang, Wen Chang, and Lu Cun or Hua Lu meet, the Yang Liang Chang Lu pattern can appear. This is especially favorable for exams, rank, official recognition, and respected professional status.
3. Yue Lang Tian Men
Yue Lang Tian Men refers to Tai Yin in Hai, the bright Moon at the heavenly gate. This is one of Tai Yin's strongest positions.
The pattern favors wealth, property, refinement, and influence. The Career Palace often receives support from a strong Yang Liang structure in Mao.
Suitable fields:
- Finance and wealth management.
- Real estate and property.
- Arts, culture, design, and refined industries.
- Behind-the-scenes management.
- Family business or long-term asset planning.
Traits:
- Strong money and property sense.
- Elegant and restrained temperament.
- Good accumulation ability.
- Stable and careful life strategy.
Year-stem differences matter. Ren year can create a double-Lu effect and strong auspiciousness. Yi year may bring Lu Cun in the same palace but requires attention to Tai Yin Hua Ji. Bing year can create Tian Tong Hua Lu in the Spirit Palace and Wen Chang Hua Ke, forming a stronger support network. Without auspicious support, the pattern is reduced and may show wealth without full nobility.
4. Sun and Moon Same Palace in Chou or Wei
Tai Yang and Tai Yin share a palace only in Chou or Wei.
| Palace | Sun-Moon condition | Reading emphasis |
|---|---|---|
| Chou | Tai Yang fallen, Tai Yin moderate | Night birth favors Tai Yin; day birth is weaker |
| Wei | Tai Yang moderate, Tai Yin fallen | Day birth favors Tai Yang; night birth is weaker |
The classical principle is that Sun and Moon guarding the Life Palace is usually weaker than Sun and Moon shining into it. The reason is structural: the San Fang support is often not strong enough, and kinship-related harm can become more visible.
However, this is not always bad. If day birth supports the Wei palace and auspicious stars are present, Tai Yang can lead the structure. If night birth supports the Chou palace and auspicious stars are present, Tai Yin can lead the structure.
Without support, and especially with malefics, the pattern becomes weaker and more unfavorable.
The Ding year version in Wei is special: Tai Yin Hua Lu may appear with Qing Yang, creating auspiciousness hidden inside harshness. If later timing triggers Hua Ji, success and failure may alternate, and people or wealth may disperse.
5. Ri Yue Fan Bei
Ri Yue Fan Bei means the Sun and Moon are both turned away from brightness. Tai Yang is fallen and Tai Yin is also fallen, yet they meet through the structure.
Basic meanings:
- Less support from parents or ancestors.
- Thin kinship support.
- Harder to rely on inherited property.
- More self-made development.
- Toil, wandering, or repeated effort when harsh stars are present.
With malefics and Hua Ji, this pattern can indicate more strain, failure, or family-related difficulty. But it is not automatically tragic. If the Life Palace is strong, no malefics damage the pattern, and auspicious transformations gather, the structure can flip into achievement through hardship. The person may succeed, but the life rhythm is still busy and laborious.
Other Sun-Moon Structures
Ri Yue Zhao Bi
Ri Yue Zhao Bi appears when strong Sun and Moon shine into the Property Palace, or when a strong Life Palace is flanked or supported by strong Sun-Moon light. It is favorable for property, inheritance, housing, and accumulation, especially when Lu-related stars are present.
Sun-Moon Flanking Life or Wealth
Sun and Moon can flank an important palace.
| Type | Example | Result |
|---|---|---|
| Strong flanking | Tai Yang in Wu and Tai Yin in Shen flanking Wei; or Tai Yang in Yin and Tai Yin in Zi flanking Chou | Can support authority or wealth if the flanked palace is strong |
| Weak flanking | Tai Yang in Shen and Tai Yin in Wu, or Tai Yang in Zi and Tai Yin in Yin | May produce name without substance or benefit without durability |
The flanking stars and the flanked palace must both be strong. Flanking alone is not enough.
Ri Yue Tong Lin
Ri Yue Tong Lin refers to an empty Life Palace in Chou or Wei with Sun and Moon in the opposite palace. It can support career achievement, but is usually not the highest level unless the Body Palace and supporting structure are strong. Life in Wei meeting Ju Men and Tian Ji in Mao is often better than Life in Chou.
Palace Effects
Life Palace
When Sun-Moon structure affects the Life Palace:
- Ri Yue Bing Ming: bright, open, reputable, benefactor-supported.
- Ri Zhao Lei Men: public ability, leadership, service, but watch heart and eyes.
- Yue Lang Tian Men: wealth and property sense, refined and reserved.
- Sun-Moon same palace: balance is possible, but support is needed.
- Ri Yue Fan Bei: self-reliance, less ancestral support, success through effort.
Spouse Palace
Strong Tai Yang in the Spouse Palace often indicates an active or career-minded partner. Strong Tai Yin indicates a reserved, family-oriented, or financially careful partner.
Sun-Moon same palace depends heavily on day or night birth. Ri Yue Bing Ming favors harmony and partner support. Ri Yue Fan Bei can show thinner spouse fate or a partner who works hard.
A special structure sometimes called Chan Gong Zhe Gui can appear when Tai Yin and Wen Qu are strong in the Spouse Palace and the Career Palace is also good. It can indicate literary, exam, or status gains connected to the spouse.
Wealth Palace
Strong Tai Yin is especially favorable for wealth accumulation, savings, property, and inheritance. Strong Tai Yang earns through reputation, service, leadership, and public value.
Fallen Sun or Moon tends to make money harder-earned. Strong Sun-Moon flanking the Wealth Palace can be powerful if the central palace is also strong.
Career Palace
Strong Tai Yang favors visible work, leadership, public service, education, law, and reputation-based careers. Strong Tai Yin favors finance, property, internal management, design, culture, and preservation.
Sun-Moon same palace can show multi-track career development, but the person needs to avoid scattering effort. Yang Liang structures are often good for intelligence, principle, and professional standing.
Property Palace
Strong Tai Yin is very favorable for property, inheritance, savings, and a stable home base. Strong Tai Yang can indicate visible buildings, open spaces, or public-facing property environments. Ri Yue Zhao Bi is especially helpful for accumulation. Fallen Sun-Moon may indicate little ancestral estate or a home environment that feels less bright.
Helpful Stars
| Star or group | Effect |
|---|---|
| Zuo Fu, You Bi | Help Tai Yang express career and public value fully |
| Wen Chang, Wen Qu | Add talent, literature, learning, and expression |
| Lu Cun, Hua Lu | Improve wealth, but work best when the main stars are strong |
| Tian Kui, Tian Yue | Add benefactor support |
| San Qi Jia Hui | Can resolve some disadvantage in Ri Yue Fan Bei |
When Sun and Moon are strong, Chang and Qu can create real brilliance. When Sun and Moon are fallen, the same literary stars may become surface display without enough foundation.
Harsh Stars and Hua Ji
| Harsh factor | Meaning |
|---|---|
| Qing Yang | Strong Tai Yang dislikes Qing Yang most; it can break brightness and harm kinship or wealth themes |
| Tuo Luo | Delay, obstruction, repeated effort |
| Mars and Bell Star | Impatience, volatility, and sudden conflict |
| Di Kong and Di Jie | Dilute career drive or wealth preservation; with strong support, hardship can still lead to rise |
| Tai Yang Hua Ji | Disputes, toil, eye issues, male-relative concerns |
| Tai Yin Hua Ji | Money loss, property issues, female-relative concerns |
One Hua Ji or one to two malefics do not always destroy a strong Tai Yang structure, except that Qing Yang must be treated carefully. Often the result becomes toil or wealth without full nobility rather than complete failure.
The harsh result is usually activated when Hua Ji and malefics collide. A noble star in a kinship palace meeting heavy harshness can show isolation or harm in family relationships: Tai Yang for male relatives, Tai Yin for female relatives.
Practical Advice by Pattern
Ri Yue Bing Ming
Use openness, reputation, and trust as your foundation. Your chart benefits from doing things in a visible and honorable way. Avoid hiding problems or damaging credibility, because reputation is part of the pattern's wealth.
Ri Zhao Lei Men
Choose work where your ability can be seen. Public service, education, law, leadership, consulting, and communication can all fit. Watch burnout, eyes, and heart stress.
Yue Lang Tian Men
Focus on accumulation, property, finance, and refined skills. Your best results often come from patience and long-term value, not from loud competition.
Sun-Moon Same Palace
Know which light is stronger. Day birth in Wei often leans toward Tai Yang. Night birth in Chou often leans toward Tai Yin. Build your life around the stronger side and use auspicious support to stabilize the weaker side.
Ri Yue Fan Bei
Do not measure your life by ancestral support. This structure often succeeds through self-reliance and repeated effort. If the chart is strong, hardship can become credibility.
FAQ
Is Sun-Moon same palace always bad?
No. It depends on Chou or Wei, day or night birth, star brightness, auspicious support, and malefic damage. It is weaker than a clean shining pattern, but it can still work when the stronger light is supported.
How do I know whether my chart is Ri Yue Bing Ming or Ri Yue Fan Bei?
Check whether both Tai Yang and Tai Yin are in strong positions and whether they meet through San Fang Si Zheng. If both are weak or fallen, the structure is closer to Ri Yue Fan Bei. Then check Four Transformations and harsh stars.
Is Ri Yue Fan Bei necessarily bad?
No. It often means less inherited support and more toil, but a strong Life Palace, auspicious transformations, and fewer malefics can turn it into success through hardship.
Why do Sun and Moon affect family relationships?
Tai Yang and Tai Yin are bright noble stars with family symbolism. Tai Yang relates to father, husband, and male relatives. Tai Yin relates to mother, wife, and female relatives. When placed in kinship palaces and damaged by harsh stars, these themes become easier to see.
