Qi Sha (七殺) — The Seven Killings Star

Qi Sha is the system’s general star — the personality that takes on hard problems by force. Its English name sounds violent; the classical reading is more precise: it is the star of decisive action, including the kind that cannot be taken back.


About Qi Sha

The name 七殺 (literally ‘seven killings’) refers in classical astronomy to a stellar position in the southern sky associated with military command. Element is Yin Metal with a recognised secondary Fire quality — the combination of cutting precision and burning forward momentum. Qi Sha is grouped under the Southern Dipper and forms one of the system’s most important triangular relationships with Zi Wei and Po Jun: in any chart, these three stars sit at fixed 120-degree angles to each other, forming the ‘Sha-Po-Lang’ trinity that classical commentary treats as the engine of major life transitions.

Practitioners read Qi Sha prominently in entrepreneurs who change industries, professional military and security personnel, surgeons, athletes in contact sports, and (notably) people whose careers involve a single decisive choice that closes off other options. The classical phrase 七殺朝斗 (‘Seven Killings facing the dipper’) describes a Qi Sha placement in the Wu (午) palace facing Zi Wei in Zi (子), and is read as one of the more powerful executive configurations in the system — the general who serves the sovereign well.

Qi Sha does not undergo the Four Transformations directly in the standard Northern Sect tradition. Its reading depends almost entirely on the company it keeps. With the ‘Six Auspicious’ helpers and a strong supporting Zi Wei, Qi Sha reads as an executive of the highest order. With the ‘Four Killings’ in the same palace, the same Qi Sha reads as the person whose decisive action becomes self-destructive — the founder who burns the company down, the surgeon whose hand is too quick. Pairings: Qi Sha + Wu Qu (executive plus execution, classical signature of senior operating leadership), Qi Sha + Lian Zhen (decisive plus principled, often producing legal or military judgment roles).

How to read Qi Sha in a chart

A Main Star never reads in isolation. Qi Sha takes its specific meaning from four interacting layers: which of the 12 palaces it lands in, what other stars share or oppose that palace, whether any of the Four Transformations (四化) activate it for your day stem, and what the 10-year and annual luck periods do to the surrounding configuration.

The fastest way to start: identify which palace Qi Sha occupies in your own chart (Self, Wealth, Career, Spouse, etc.), then look at the directly opposing palace — the two are read together. Next, check whether any of the Four Auspicious helpers (左輔 Zuǒ Fǔ, 右弼 Yòu Bì, 文昌 Wén Chāng, 文曲 Wén Qū) or Four Killings (擎羊 Qíng Yáng, 陀羅 Tuó Luó, 火星 Huǒ Xīng, 鈴星 Líng Xīng) sit in the same palace — these strongly modulate the star’s expression.

Once you have those three layers, the reference description on this page becomes contextual rather than absolute. Qi Sha in your Wealth palace alongside Wu Qu reads very differently from Qi Sha in your Spouse palace alongside Tan Lang, even though it is the same star. For chart-specific interpretation, run your Zi Wei Dou Shu chart or book a consultation.

Frequently asked questions

Is Qi Sha a good or bad star to have in my chart?

Zi Wei Dou Shu does not read Main Stars as inherently auspicious or inauspicious. Every Main Star, including Qi Sha, has palace contexts where its character serves the person well and contexts where the same character creates friction. The classical reading depends on three things: which palace the star occupies, what other stars share or oppose it, and whether the Four Transformations (四化) activate it for your day stem. Treat the description on this page as a baseline portrait of the star’s nature, then adjust for those three contextual factors when reading your own chart.

Can Qi Sha appear in any of the 12 palaces?

Yes. The 14 Main Stars rotate through the 12 palaces in fixed astronomical patterns determined by your birth date and time, so Qi Sha can theoretically land in any palace — Self, Siblings, Spouse, Children, Wealth, Health, Travel, Friends, Career, Property, Fortune, or Parents. The palace it lands in is the single most important factor in interpreting what Qi Sha means for your specific chart, because each palace assigns the star to a different domain of life.
