Zi Wei Dou Shu Chart: 12 Palaces and Main Stars

How the chart is built

Zi Wei Dou Shu, often translated as Purple Star Astrology, uses your birth year, month and day in the Chinese lunar calendar, plus your two-hour birth period. Your birth month and hour fix which of the twelve boxes becomes your Life palace. Your birth day and a number called the element bureau then place the Zi Wei star itself, and the remaining main stars follow by fixed rules. That is why being off by one two-hour period moves the Life palace by one box and changes the whole chart.

What each of the twelve palaces covers

The palaces cut life into twelve areas. Starting from the Life palace, they run:

Life: your basic temperament and way of doing things, the core of the chart.
Siblings: brothers and sisters, and peers you work alongside.
Spouse: what you want in a close relationship and how you tend to behave in one.
Children: children and younger people, and often the work or students you bring up.
Wealth: how you earn and spend, not how much you will have.
Health: traditionally the body, and also used for how you carry pressure. It is no substitute for a doctor.
Travel: how you are away from home, in new surroundings, and out in the wider world.
Friends (also called Servants): friends, colleagues and people who report to you, and how you work in a group.
Career: work, vocation and the kind of stage that suits you.
Property: home, where you live, family assets, and what kind of base you need.
Fortune and virtue: inner life, pleasures and interests, and what you truly care about.
Parents: parents, bosses, elders, and your relationship with rules and institutions.

What the main stars are

There are fourteen main stars: Zi Wei, Tian Ji, Tai Yang, Wu Qu, Tian Tong, Lian Zhen, Tian Fu, Tai Yin, Tan Lang, Ju Men, Tian Xiang, Tian Liang, Qi Sha and Po Jun. Each has its own character. Qi Sha is driven and willing to break new ground, Tian Tong is gentle and values comfort, and Ju Men is sharply analytical but prone to friction over words.

A star's palace shows where its character plays out. Someone with Qi Sha in the Life palace tends to act decisively. Qi Sha in the Spouse palace is often read as needing a partner with a mind of their own who does not cling. A palace with no main star is called empty, and it is usually read by borrowing the stars from the palace opposite.

What the four transformations are

The four transformations are four kinds of change, and the stem of your birth year decides which four stars carry them:

Lu (prosperity): things flow, resources and connections arrive easily.
Quan (power): a drive to take charge and have the final say.
Ke (reputation): order, recognition, doing things with grace.
Ji (obsession): fixation, sticking points, what you cannot let go of. This is where the chart asks the most care from you.

Beyond the birth year, each palace has a stem of its own that can send out transformations into other palaces. This is called flying transformations, and it is used to see how one area of life pulls on another, such as how a change at work ripples into home.

Decade periods and annual periods

Decade periods move one palace every ten years. They start from the Life palace and run forward or backward depending on your sex and whether your birth year is yin or yang. The starting age, somewhere between two and six, comes from your element bureau. Whichever palace your current decade sits in sets the theme for those ten years. Annual periods show which palace each calendar year falls in, and speak to that year's focus.

How a real question gets read

Question: "Should I accept a two-year posting to another city?"

A useful reading puts three pieces together. The Travel palace shows whether you open up in new surroundings or struggle to settle. The Career palace shows what kind of stage you do your best work on, and whether the posting fits. Then look at which palace your current decade sits in and whether any transformation lights up or snags Travel or Career. If Ji happens to land in Travel, that is not necessarily "don't go". It is a reminder to settle the one thing you cannot let go of before you leave, such as care for a family member or an understanding with your partner.

Zi Wei in LifeOs

Once you sign in and add your birth details, open the Zi Wei data page from "Self-understanding" on the home screen. You will see the main stars in each of the twelve palaces, flying transformations, the pattern of your Life palace, your decade and annual periods, and the structural features on record. It is a data view, so it uses the technical terms directly. At the top of the page you can copy Zi Wei-only reading instructions and paste them into the chat assistant you use, asking it to translate each point into plain language.

BaZi, the other birth-time system with its own data page, is worth reading alongside it. If you would rather skip the terms entirely, your life manual combines Zi Wei with seven other traditions into plain-language chapters with no jargon or numbers.

Frequently asked questions

How is Zi Wei Dou Shu different from BaZi?

Both start from your birth time. BaZi writes it as eight characters and reads the relationships between the elements. Zi Wei divides life into twelve palaces and reads where the stars fall. One leans toward structure and the other toward life areas, so they make good cross-references.

Can I read a Zi Wei chart without an exact birth time?

The birth hour decides which box is your Life palace, so a wrong hour shifts the whole chart. A time from a birth certificate is best if you can find one.

Is the Ji transformation bad news?

No. Ji marks the area where you are especially fixated and invested, which is exactly why you get stuck there and why it rewards attention. It is not a forecast of misfortune.

Will the Zi Wei data page tell me which years are good or bad?

No. It lists the palace and transformations for each decade and year without labeling any period as good or bad, so you can compare them with your own experience.
