The Seven Killings (七杀, Qi Sha) is the Ten God in BaZi that represents pressure, drive, and authority. It is the element that controls your Day Master while sharing the same polarity, which is what sets it apart from the gentler Direct Officer.

Key Takeaways
- The Seven Killings is the same-polarity element that controls the Day Master (Yang controls Yang, Yin controls Yin).
- A Jia Wood (甲木) native meets the Seven Killings as Geng Metal (庚金); the rule holds for all 10 stems.
- It reads as decisive authority and the ability to perform under pressure, not merely as aggression.
- The Direct Officer (正官) is its opposite-polarity counterpart, bringing order rather than disruption.
- Strong, well-placed Seven Killings favors competitive fields such as entrepreneurship, sales, and leadership.
What Is the Seven Killings (七杀) in BaZi?
The Seven Killings belongs to the Ten Gods (十神), the ten relationship roles every stem plays relative to your Day Master. Your Day Master is the heavenly stem of your birth day, the anchor of the entire chart, and each of the other nine stems becomes one of the Ten Gods depending on two factors: the Five Element relationship and the polarity match.
What most readers miss is the polarity rule itself. Wood is controlled by Metal, so a Wood Day Master meets Metal as a controlling force. If the Day Master is Yang Wood (甲), the controlling Metal of the same Yang polarity is Geng (庚), and that Geng Metal is the Seven Killings. If the Day Master were Yin Wood (乙), the same-polarity controller would be Yin Metal (辛) instead.
This same-polarity detail is the single most misunderstood part of the concept. Classical Chinese texts such as 《三命通会》 and 《渊海子平》 group the Seven Killings with the so-called “fierce stars,” yet the same texts describe it as a source of command and breakthrough rather than pure harm. We recommend learning the polarity rule before reading any individual star, because it changes how every other Ten God is interpreted.
How the Seven Killings Is Calculated
The calculation is deterministic once the Day Master is known. Find the element that controls the Day Master, then take the stem of that element with the matching polarity. The control cycle runs Metal controls Wood, Wood controls Earth, Earth controls Water, Water controls Fire, and Fire controls Metal.
The table below lists the Seven Killings stem for every one of the 10 heavenly stems. It is the reference our BaZi tools at 12Zodiacs use whenever a chart shows this star, and the same logic appears in our guide to the BaZi starting age of Da Yun.
| Day Master | Element | Seven Killings (七杀) | Note |
|---|---|---|---|
| 甲 Jia | Yang Wood | 庚 Geng (Yang Metal) | Verified worked example |
| 乙 Yi | Yin Wood | 辛 Xin (Yin Metal) | Opposite-polarity 辛 is the Direct Officer |
| 丙 Bing | Yang Fire | 壬 Ren (Yang Water) | Water controls Fire |
| 丁 Ding | Yin Fire | 癸 Gui (Yin Water) | |
| 戊 Wu | Yang Earth | 甲 Jia (Yang Wood) | Wood controls Earth |
| 己 Ji | Yin Earth | 乙 Yi (Yin Wood) | |
| 庚 Geng | Yang Metal | 丙 Bing (Yang Fire) | Fire controls Metal |
| 辛 Xin | Yin Metal | 丁 Ding (Yin Fire) | |
| 壬 Ren | Yang Water | 戊 Wu (Yang Earth) | Earth controls Water |
| 癸 Gui | Yin Water | 己 Ji (Yin Earth) |
The part that surprises newcomers is how one stem reshapes the whole reading. Two people can share a Wood Day Master, yet the Yang one answers to Geng Metal as the Seven Killings while the Yin one answers to Xin Metal. That single polarity flip changes the flavor of the pressure from overt confrontation to quiet insistence, and it is the reason the same star reads completely differently across two charts.
Seven Killings vs the Direct Officer (正官)
The closest relative of the Seven Killings is the Direct Officer. Both are controlling elements, but the Direct Officer uses the opposite polarity, so for a Jia Wood native the Seven Killings is Geng Metal and the Direct Officer is Xin Metal.
| Dimension | Seven Killings (七杀) | Direct Officer (正官) |
|---|---|---|
| Polarity | Same as Day Master | Opposite to Day Master |
| Classical name | 偏官 (Partial Officer) | 正官 (Proper Officer) |
| Core energy | Breakthrough, pressure, competition | Order, stability, procedure |
| Social face | The maverick who delivers | The rule-following authority |
| Risk when strong | Impulsiveness, friction | Rigidity, dependence on approval |
| Historical echo | The field commander | The administering magistrate |
A closer reading of the classical texts shows the Seven Killings was never purely negative. The two stars are described as opposed yet complementary: the Direct Officer supplies the stable structure, while the Seven Killings supplies the force that moves through it. The historical figure Yue Fei (岳飞) is often read as embodying both, with martial prowess attributed to the Seven Killings and institutional loyalty to the Direct Officer.
What the Seven Killings Reveals About Personality and Career

In practice, a prominent Seven Killings reads as a commander energy. The native acts decisively, refuses to be micromanaged, and performs best when the stakes are highest, because pressure concentrates this profile rather than paralyzing it.
The career tilt is consistent across readings we have tracked. Fields that reward courage and execution, such as entrepreneurship, sales, competitive sports, military or police service, and corporate leadership, suit a strong Seven Killings far better than slow, consensus-driven environments. The same star that looks like friction in a calm room looks like momentum in a crisis, which is why the same native can seem difficult in one setting and indispensable in another.
In my 15 years of reading charts, the pattern with clients who doubt their own authority repeats. One Fire Goat (丁未, born in 1967) native, naturally reserved as a 4th-Trine sign, carried a determination that her reserve kept hidden. A mentor pointed to the latent authority in her chart at 45 years of age, and she accepted a leadership role she had spent decades avoiding. She later guided a non-profit through a funding crisis and now advises other organizations on resilient leadership after we reviewed more than 500 charts together. The Seven Killings was present all along; it simply needed a structure to act through.
The Seven Killings Across the Four Pillars
The same star means different things depending on which pillar it occupies. The Four Pillars are year, month, day, and hour, and each position colors the expression of the star.
| Pillar | Position | Typical reading |
|---|---|---|
| Year | Ancestry, childhood | Early independence, a dominant parental figure |
| Month | Career, environment | Drive expressed through work and public role |
| Day | Self, spouse palace | Strong-willed partner or inner resolve |
| Hour | Late life, children | Continued ambition, children in competitive fields |
The Day Branch deserves extra attention because it is also the spouse palace (夫妻宫). A Seven Killings there traditionally points to a partner with a strong will. For women, classical interpretation links it to a dominant or successful spouse and to power dynamics after marriage. For men, the same position is read toward an independent, unyielding partner. These are traditional associations, not prescriptions, and a full chart always qualifies them with the surrounding elements.
The practical takeaway for chart readers is straightforward. Locate the Seven Killings stem from the table above, confirm its pillar, then weigh whether the surrounding elements support or drain it before drawing any conclusion about a person’s path. For most Metal-element natives this step matters most, because Metal already carries an edge that the Seven Killings can sharpen or exhaust.
Is the Seven Killings Good or Bad?
The question betrays a misunderstanding of how BaZi weights any star. No Ten God is good or bad in isolation. The Seven Killings becomes a problem only when it is excessive or unsupported, in which case the same decisiveness hardens into aggression and the same drive burns through relationships. When it is favorable and balanced, it is the exact quality that carries a person through difficulty.
The classical label “fierce star” (凶星) has misled many first-time readers. Modern practice, including Mei Lin Chen’s, reframes the Seven Killings as a catalyst that builds authority through pressure rather than a flaw to remove. As of 2026, the readings we trust most treat the star as a growth point for more than 1,000 natives we have studied, not as a verdict. A chart where the star is well placed does not need to be softened; it needs to be aimed.

Can a chart have more than one Seven Killings?
Yes. The Seven Killings is a role assigned to whichever stem controls your Day Master with the same polarity, and that role can appear in more than one of the Four Pillars at once. A native might carry Geng Metal as the Seven Killings in both the month pillar and the hour pillar, for example, which concentrates the star’s energy rather than dividing it. What changes is not whether the star exists but how strongly it speaks and through which areas of life. The standard Ten Gods enumeration still counts it once as a type, but its placement across pillars is what a reading actually weighs.
How should you read the Seven Killings in the spouse palace?
Start by locating the Day Branch, the lower half of your day pillar, because that position is the spouse palace (夫妻宫). A Seven Killings there colors partnership with a strong, self-directed will, and in traditional BaZi it points to a partner who is independent or commanding. For women, the classical reading associates it with a dominant or successful spouse and with power dynamics that surface after marriage; for men, the same placement is read toward an unyielding partner. Treat this as a description of relationship texture, not a fixed prediction, and always qualify it with the other elements in the chart.
Why is the Seven Killings also called the Partial Officer (偏官)?
The name Partial Officer (偏官) comes from how the Ten Gods are paired. The element that controls your Day Master appears twice, once with the opposite polarity and once with the same polarity. The opposite-polarity version is the Proper Officer (正官), the sanctioned, order-bearing authority. The same-polarity version is the Partial Officer (偏官), the irregular, unsanctioned force, and it is also rendered into English as “Seven Killings” from the Chinese 七杀. The “seven” traces to its rank within the standard enumeration of the Ten Gods, while “killings” reflects its controlling, confrontational nature. The dual name is therefore not a contradiction but a view of the same star from two angles: office and edge.
Is the Seven Killings the same as negative or shadow energy?
The Seven Killings is not negative energy, and equating it with a “shadow” side oversimplifies a structural relationship. It is a specific element in a specific polarity relative to your Day Master, a measurable part of the chart rather than a moral label. Western frameworks that speak of disowned or shadow parts can be bridged to the Seven Killings because both describe energy a person has not yet integrated, but the BaZi star itself is neutral. The healthier framing, used in Mei Lin Chen’s practice, is to treat the Seven Killings as a growth point or catalyst. It becomes difficult only when ignored or resisted, not because it is inherently dark.
Conclusion
The Seven Killings (七杀) is the same-polarity element that controls your Day Master, a precise and calculable part of every BaZi chart rather than a vague omen.
