To read marriage in a BaZi chart, start with the Spouse Palace (the Earthly Branch of the Day Pillar) and the Spouse Star (正财/偏财 for men, 正官/七杀 for women). These two elements reveal the nature, timing, and quality of your marital life. The foundation lies in the balance between them and the interaction with the Useful God（用神）. Below, I break down the key components a practitioner requires.

The Spouse Palace: The Day Branch

The Day Branch (日支) represents the spouse's palace — the seat where the spouse resides in your life. Its Heavenly Stem and Earthly Branch, along with their interactions with other pillars, define core marital traits.

- Stem and Branch combination: The Day Stem is YOU; the Day Branch is your spouse. If the Branch supports the Stem (e.g., by producing it), the spouse tends to be supportive. If it conflicts (克, 冲), friction is likely. - Six Combinations（六合）, Three Combinations（三合）, Punishments（刑）, or Clashes（冲） with other branches: A Day Branch that clashes with the Month Branch often indicates an unstable marriage or late marriage. A combination can signify harmony but might also mean the spouse is distracted by external relationships. - Hidden Stems（藏干） in the Day Branch: They reveal the spouse's personality traits and hidden influences. For example, a 藏干 of 劫财 may imply a rival or financial strain.

Classical source: 《滴天髓》 says, “The Spouse Palace is the seat of the partner; if it is stable and favorable, the marriage is stable.”

The Spouse Star: Where Is Your Partner?

The Spouse Star is the Heavenly Stem that represents the spouse's energy: - For men: 正财 is the wife (primary), 偏财 is a secondary partner. - For women: 正官 is the husband (primary), 七杀 is a secondary partner.

Examine: - Appearance in the Four Pillars: If the Spouse Star appears in the Year Pillar, marriage tends to happen early or be influenced by family. In the Hour Pillar, it may indicate a late marriage or a second relationship. - Strong or weak: A strong Spouse Star that is also a Useful God (用神) usually means the spouse is beneficial to your life. If it is a 忌神 (harmful element), the spouse may cause stress. - Combination or clash: If the Spouse Star combines with another stem (合), it can indicate multiple partners or an extramarital affair. A clash (冲) often signals separation or divorce.

《子平真诠》 emphasizes: “The Spouse Star must be examined in relation to the Day Master’s strength and the season; an overly strong Spouse Star overwhelms, an overly weak one is absent.”

The Useful God and Spouse Star Interaction

The Useful God is the element that brings balance to your chart. When your Spouse Star is the Useful God, marriage is typically a source of support. When it is the opponent (忌神), your spouse might become an obstacle.

- Example: A man born in a winter month with a cold Water Day Master (壬水) needs Fire (暖局). If his 正财 is Fire (午,丙), his wife will warm his life. If his 正财 is a Water (e.g., 癸水), it may increase coldness.

《穷通宝鉴》 provides detailed seasonal rules: “In summer, a Water Star is precious; in winter, a Fire Star is noble.”

Timing Markers: Peach Blossom, Red Luan, and Heavenly Happiness

- Peach Blossom（桃花）: The Earthly Branches 子, 午, 卯, 酉 appearing in the chart indicate romantic opportunities. A Peach Blossom in the Day Branch can mean the spouse is attractive, but also prone to affairs. - Red Luan（红鸾） and Heavenly Happiness（天喜）: These are annual stars that signal marriage or relationship milestones. They move based on the birth year. For example, a Red Luan year often brings a marriage proposal or new romance. - 大运 (Decade Luck) and 流年 (Annual Luck): When a Luck Pillar or Year contains the Spouse Star, a combiner, or a Punisher of the Spouse Palace, marriage events are likely.

The Mismatch Problem: Spouse Palace vs. Spouse Star

Sometimes the Spouse Palace (Day Branch) and the Spouse Star (Heavenly Stem) contradict each other. For example: - The Day Branch is 午火 (Fire), and the Spouse Star is 壬水 (Water) hidden elsewhere. Fire and Water clash — this suggests the spouse's personality or role conflicts with what the palace indicates. Such mismatches often lead to rocky relationships or divorce. - Solution: Check if the Spouse Star is actually present in the Day Branch’s hidden stems. If not, the spouse may feel absent or incompatible.

Practical Steps

1. **Identify the Spouse Star** based on your gender and Day Master. 2. **Locate the Spouse Palace**: Day Branch. 3. **Assess the Spouse Star’s strength and position**: Is it in the proper pillar? Is it combined with other stars? 4. **Compare the Spouse Palace with the Useful God**: Is the branch favorable? 5. **Look for Red Luan and Peach Blossom in luck years**: They pinpoint timing. 6. **Note any 冲, 刑, 合, 害** between the Spouse Palace and other branches.

What BaZi Reveals vs. Doesn’t

BaZi shows patterns and tendencies, not fixed outcomes. A chart with a troublesome Spouse Palace does not guarantee divorce — free will and environment play huge roles. It reveals the innate challenges and strengths you bring to a relationship. For deeper analysis, always cross-reference with the actual circumstances and other branches like parents or children.

Classical References in Summary

- 《滴天髓》: “The Spouse Palace should be in harmony with the Day Master; a clash means many changes.” - 《子平真诠》: “For women, the official star should be alone and pure; for men, the wealth star should be clear and strong.” - 《三命通会》: “Peach Blossom in the Spouse Palace often leads to beauty but also instability.” - 《穷通宝典》: “In the analysis of marriage, never separate the Spouse Palace from the Useful God.”

Final Advice

Remember to check both the Ten Gods (十神) relationships and the Five Elements interactions. The spouse is not just a star; the palace is their home. When the home is peaceful (生,合) and the star is benevolent (不冲不克), marriage flourishes. When they fight, the relationship bears the scars.

As a practitioner, always combine chart logic with human reality — BaZi is a mirror, not a prison.
