If the fourteen major stars are the actors in Zi Wei Dou Shu (紫微斗数 zǐwēi dǒushù), the twelve palaces are the stage they stand on. The whole system is a ring of twelve houses, each governing one domain of life, and the Zi Wei Dou Shu palaces are read one by one — marriage in its own house, wealth in its own house, health in its own house. This is why the method is prized for detail: nothing is averaged out. To read a chart at all, you first have to know what each of the twelve rooms is for.
Before we lay them out, one thing worth stating plainly. The chart is deterministic — the position of every palace and star is fixed by the lunar birth date and hour, computed through the Five Element Bureau (五行局 wǔxíng jú). A practitioner interprets a finished chart; the placements are never guessed. What follows is the system, not any one person’s reading.
The twelve palaces 十二宫 at a glance
The twelve palaces (十二宫 shí’èr gōng) sit on the twelve earthly branches in a fixed ring. Once the Life palace is located, the other eleven follow in strict order around it. Here is the full set, copied from the classical arrangement:

The Life palace (命宫 mìng gōng) is the first house and the one everything else is measured against. It is located from the lunar month and the birth hour, and once it is fixed, the other eleven Zi Wei Dou Shu palaces fall into their branches automatically. Think of it as the keystone: move it and the whole ring turns with it.
The 命宫 describes the self at the deepest level — temperament, the grain of the personality, the way a person meets the world before circumstance shapes them. Whichever of the fourteen major stars sits here colours the entire chart. A 命宫 carrying 紫微 (Zǐwēi, the Emperor) reads very differently from one carrying 七杀 (Qīshā, the General), and that difference ripples out to how wealth, marriage, and career are approached. This is why the Life palace is always read first; the other houses are context around it.
It also sets the Five Element Bureau, which fixes where 紫微 sits and therefore where the other thirteen majors land. If you are still building intuition for who those stars are, the companion piece on the fourteen major stars of Zi Wei Dou Shu walks through each one and the role it plays inside a palace.
The Body palace 身宫 and the second half of life
Alongside the twelve is a thirteenth reference point: the Body palace (身宫 shēn gōng). It is not a separate house. Instead it overlaps one of the existing twelve — it might land on the Wealth palace, the Marriage palace, the Career palace, and so on. Where it falls tells you which domain grows in weight as life goes on.
The working distinction practitioners use is this: the 命宫 governs the innate self and the early emphasis of life, while the 身宫 marks what a person moves toward and cultivates in the later years. A chart whose Body palace sits on the Career palace suggests a life that increasingly organises itself around work and status; one whose Body palace sits on the Marriage palace points toward partnership becoming the centre of gravity. The two are read together, not in isolation — the self you start with and the self you build toward.
Reading palaces in relationship, not isolation
A common beginner mistake is to read each palace as a sealed box. The palaces talk to one another. The 三合派 (sān hé pài, San He, Trinity school) reads them in trines — groups of houses set 120 degrees apart on the ring that reinforce one theme — while the 飞星派 (fēi xīng pài, Fei Xing, Flying Star school) follows the four transformations as they fly from one palace into another. Which lens you use changes what you emphasise, and the schools should not be blurred together.
The practical upshot: a weak-looking Wealth palace is not a verdict of poverty if the palaces in trine with it are strong, and a bright Marriage palace can still be tested by an affliction flying in from elsewhere. The twelve rooms are a network, and a good reading traces the connections rather than judging each room alone. For the wider frame around all of this — what the system is and where it comes from — the introduction to Zi Wei Dou Shu and the Purple Star hub are the places to start.
Zi Wei Dou Shu is often read beside Ba Zi (八字 bāzì): the palaces give a room-by-room map, while Ba Zi reads elemental balance and timing across the four pillars. The two systems check each other. While the Purple Star chart tool is still in the works, you can already plot your Four Pillars and see your elements laid out — build your free Ba Zi chart with the calculator and start reading your own life one house at a time.
