What the Moon Star means in Ziwei Doushu
Taiyin stands for home, feelings and wealth that builds up slowly. Wherever it sits, you tend to tend that part of life with care.
A chart has twelve cells, called palaces. Each palace covers one area of life. Enter your birth date and hour in the free Ziwei Doushu calculator. The chart labels are in Chinese, so look for the cell showing 太陰. Check the branch of that cell first, then the brightness mark beside the star.

Why old texts call Taiyin the lord of home and property
Taiyin is called the lord of home and property because it rules your house and what you own.
This covers more than the building. It also means your living space and your sense of safety. When Taiyin works well, you tend to value a settled home and are more willing to save for one.
Old texts also pair Taiyin with Taiyang, the Sun Star. The Sun rules the day, and the Moon rules the night.
Taiyin's brightness in the twelve branches: brightest in Hai, Zi and Chou
Taiyin is brightest in Hai, Zi and Chou, where it is at Temple. It is dimmest in Mao, Chen and Si, where it is Fallen. Each of the twelve cells is marked with an Earthly Branch. Brightness says how freely a star works in that cell.
There are seven levels. The strongest is Temple and the weakest is Fallen, with five steps in between: Prosperous, Gaining Ground, Beneficial, Neutral and Not Gaining Ground.
In Wu and Wei, Taiyin is Not Gaining Ground, which is not the same as Fallen. Some old texts count these two as fallen too, so tables elsewhere may differ.
Day births and night births: what is the difference?
Tradition says Taiyin prefers a night birth, so it works better for people born after dark.
This is an extra note from old texts. The brightness on the chart depends only on the branch, not on whether you were born by day or by night.
Taiyin in the Life Palace: caring, home-loving, prone to worry
With Taiyin in your Life Palace, you tend to be careful and gentle, and you value home and a sense of safety. The Life Palace is the cell about you. How this plays out also depends on the Three Directions and Four Squares (San Fang Si Zheng). That is the group of four palaces you read together.
Where you tend to shine
- You are careful and notice what others miss.
- You have a good eye and care about taste in daily life.
- You handle money steadily and save a little at a time.
Where you tend to get stuck
- You think a lot and may worry about things that have not happened.
- You keep feelings inside and may not speak up when upset.
- You like stability, so big changes can slow your decisions.
Taiyin Life Palace pairings: with Tiantong, Taiyang, Tianji or alone

The other six branches: alone
Taiyin is the only major star in your Life Palace. Read the stars in the opposite palace along with it.
Taiyin's four transformations: which years
Taiyin takes Hua Lu (wealth) in Ding years, Hua Quan (power) in Wu years, Hua Ke (fame) in Geng and Gui years and Hua Ji (obstacle) in Yi years. These names are year stems. Each year has one, and it repeats every ten years.
The Four Transformations (Si Hua) are four ways a star can change. Taiyin is the only major star that takes Hua Ke under two different stems.
The last digit of your birth year gives the stem. If your birth year ends in 7, such as 1987, Taiyin takes Hua Lu. If your birth year ends in 5, such as 1985, it takes Hua Ji. If you were born before Lunar New Year, count the previous year.
With Hua Lu, saving and buying property tend to go more smoothly. With Hua Ji, you may worry more about family or money.
Taiyin in the Property, Children and other palaces
In any other palace, Taiyin is still careful and steady, turned toward what that palace covers.
| Palace | With Taiyin here |
|---|---|
| Siblings Palace | You get along gently with siblings and peers, and you quietly look out for each other. |
| Spouse Palace | You tend to value a caring partner. Company and a sense of safety matter most in love. |
| Children Palace | You look after your children with great care, and you may also worry about them more. |
| Wealth Palace | You handle money steadily. You like to save bit by bit and avoid big risks. |

| Travel Palace | Away from home, you keep a low profile and get things done through care and goodwill. |
| Friends Palace | Your friends tend to be gentle, and your friendships build up slowly. |
| Career Palace | You pay attention to detail. Settings where you can build steadily suit you. |
| Property Palace | Taiyin already rules home and property, so it works well here. You are more willing to buy a home. |
| Fortune Palace | You are sensitive inside, and you need quiet time to sort out your feelings. |
| Parents Palace | Your bond with elders is tender, and you may have been well looked after as a child. |
