Tai Sui (太歲), also called the Grand Duke of Jupiter, is a yearly figure in traditional Chinese astrology and feng shui. Each year it is linked to one compass direction, and people traditionally avoid disturbing that direction during the year. The term is part of a folk tradition, not a scientific one.
Where the name comes from
Traditional accounts connect Tai Sui with Jupiter. Jupiter takes roughly twelve years to complete an orbit, which matches the twelve-year zodiac cycle. Accounts of the details vary, and the stories about the yearly figures are folklore rather than documented history.
How the yearly direction is set
Each year has a zodiac sign, and each sign corresponds to a point on the compass. The Tai Sui for a year is traditionally placed in that point. The table below gives the rough compass direction for each sign.
| Zodiac sign | Approximate direction |
|---|---|
| Rat | North |
| Ox | North-northeast |
| Tiger | East-northeast |
| Rabbit | East |
| Dragon | East-southeast |
| Snake | South-southeast |
| Horse | South |
| Goat | South-southwest |
| Monkey | West-southwest |
| Rooster | West |
| Dog | West-northwest |
| Pig | North-northwest |
So 2026, the Year of the Fire Horse, places Tai Sui in the South. 2027, the Year of the Goat, places it in the Southwest. Practitioners usually treat the sector as the place to avoid disturbing, not the place to avoid entirely.
What “offending Tai Sui” means
In traditional belief, people who are “offending” Tai Sui in a given year are those born in the same zodiac sign as that year, or in a sign said to clash with it. The phrase is fan tai sui (犯太歲). The traditional response is to keep a lower profile: think carefully before big decisions and avoid unnecessary risk. These are customs, not tested rules.
Traditional practice: An Tai Sui
During the Lunar New Year, many people visit Taoist or Buddhist temples for a ritual called an tai sui (安太歲), which means “pacifying Tai Sui.” Practice varies. Devotees often give their birth details, offer prayers and incense, and may receive a blessing or a protective talisman. It is a cultural custom, and people take part for different reasons.
What it means for your home
If you follow the tradition, the practical advice is to leave the Tai Sui sector undisturbed for the year. That means no digging, no heavy construction and no major moves in that direction. Nothing here overrides safety. Repairs that protect people, such as leaks, wiring or structural issues, should not wait for a sector to be clear. The Tai Sui and San Sha guide covers how to plan around the sector, and how to decide what can be postponed.
What Tai Sui does not do
Tai Sui is a traditional belief. It is not supported by controlled scientific evidence, and it does not predict specific events. It is a way of thinking about timing and caution, and that is the most useful way to read it. For the wider framework, see the Xuan Kong Flying Stars guide. The 2027 chart article shows the Tai Sui sector for that year.
