The qi men nine stars are the second layer of a Qi Men Dun Jia (奇门遁甲 qí mén dùn jiǎ) plate — the row of nine celestial markers that ride the Heaven Plate as it turns over the fixed board. Where the palaces give you the ground and the gates give you the door, the Nine Stars (九星 jiǔ xīng) describe the quality of the energy overhead: the mood, the talent, and the hazard sitting above each palace. This page lays out all nine, their elements and natures, which the classics call benefic and which they warn against, and what the season does to their strength.
Where the Nine Stars sit
A Qi Men plate is built in four layers. The Earth Plate (地盘 dì pán) holds the nine stems distributed by the formation number. Over it rotates the Heaven Plate (天盘 tiān pán), and it is the Heaven Plate that carries the Nine Stars. In the hour method, one star is singled out as the Chief (值符 zhí fú) — the commander that follows the hour’s leading stem and anchors how the whole board is read.
Each star has a fixed element and a fixed temperament, but it does not have a fixed home for the reading — it moves. So the same star can land over a Water palace in one plate and a Fire palace in another, and the interaction between the star’s element and the palace beneath it is a large part of what a practitioner weighs. To follow that, it helps to know the board first: see the Nine Palaces and their Luo Shu layout.

These are the nine, copied as the practice holds them. Note that 天禽 (Qin) is the central star; in most schools the centre palace has no gate or deity of its own, and its star is borrowed out to the 坤 (Kun) palace.

The tone column is the shorthand a practitioner reaches for first. 天冲 (Chong) is drive and speed; 天辅 (Fu) is study, teaching and steady counsel; 天心 (Xin) is skill, repair and the “physician” star; 天英 (Ying) is showing brightly, which can tip into vanity or burnout.
Which stars are benefic, which inauspicious
Among the qi men nine stars, the classics single out two as inauspicious: 天芮 (Rui), the illness star, and 天蓬 (Peng), the thief star. On the benefic side sit 天心 (Xin, healing), 天辅 (Fu, scholarship) and 天任 (Ren, steadfast). The rest — 天冲, 天禽, 天柱, 天英 — carry mixed or situational weight and are read in context.
This mirrors the way the gates split into auspicious and inauspicious sets; if you want the action layer, see the Eight Gates of Qi Men. A useful discipline: never read a star in isolation. A benefic star over a hostile palace, or an inauspicious star propped up by the season, will not behave the way its label alone suggests.
Seasonal strength: 旺相休囚死
This is the correction most beginners miss. Each star has an element, and every element passes through five states across the year — 旺相休囚死 (wàng xiàng xiū qiú sǐ): prospering, supporting, resting, trapped, and dead. The state depends on the season, exactly as it does in a Ba Zi chart. If the seasonal logic behind this is new to you, our note on the Five Elements in Ba Zi covers the same cycle of production and control.
What it does to a star is simple to state and easy to forget: strength decides whether a star can keep its promise. A benefic star like 天心 (Metal) landing in a season where Metal is prospering 旺 is a strong, reliable signal. The same star in a season where Metal is dead 死 is a good intention the season cannot fund. The reverse holds too — an inauspicious star weakened to 囚 or 死 does less harm than its label threatens, while 天蓬 (Water) at full 旺 strength is a hazard to take seriously.
So a working read runs in that order: name the star and its element, check its seasonal state, then weigh it against the palace it sits over and the palaces that produce or clash with it. The label is the headline; the season sets the volume.
Reading a star in practice
In a finished plate, a practitioner locates the star over the palace that matters to the question — the useful symbol — and reads its nature, its element, its seasonal strength, and the gate and deity sharing that palace together. A plate is deterministic: it is computed from date, time and solar term by fixed rules, not improvised, so the interpretation always anchors to what the board actually shows rather than to a wished-for position.
The Nine Stars rarely give a verdict on their own. They colour the terrain — this palace is bright and skilled, that one is sickly, this one is fast but reckless — and the reading comes from how that colour meets the gate you would move through and the season you are in.
