What is Minor Luck (Xiao Xian)?

Minor Luck (Xiao Xian) in Zi Wei Dou Shu is a second set of luck periods that moves one palace a year, and unlike the Annual Luck, which follows the calendar year and lands on the same palace for everyone, Minor Luck follows your age, so everyone moves on their own. In any given year, everyone's Annual Life Palace is on the same branch; Minor Luck is the line the old writers used to look at "you, at this age."

The short version:

• Formula: Minor Luck = age 1 starts at your birth-year trine group's palace (Yin-Wu-Xu at Chen, Shen-Zi-Chen at Xu, Si-You-Chou at Wei, Hai-Mao-Wei at Chou), then men move forward and women backward, one palace a year.
• Direction depends only on sex: unlike the Decade Luck, which also looks at the yin or yang of the birth year, men always move forward and women always backward.
• Age is traditional age: 1 at birth, plus one at each lunar new year.
• How to read it: it points to its own palace alongside the Annual Luck; read both, and pay most attention when they land on the same palace.

How Minor Luck is laid out

Volume two of the Quan Shu says:

Those born in Yin, Wu or Xu years start at Chen; those born in Shen, Zi or Chen years start at Xu; those born in Si, You or Chou years start at Wei; those born in Hai, Mao or Wei years start at Chou.

And notes:

Men count forward regardless of yin or yang; women count backward regardless of yin or yang.

In plain terms, three steps:

1. See which trine group your birth-year branch belongs to: Yin-Wu-Xu, Shen-Zi-Chen, Si-You-Chou or Hai-Mao-Wei.
2. Age 1 falls in that group's palace.
3. Men move forward and women backward, one palace for each year of age. Forward means following the branch order (Chen to Si, Si to Wu); backward is the reverse.

Starting-palace table

There's a pattern behind the starting palaces: each one is opposite the last branch of its trine group. Xu, last in Yin-Wu-Xu, is opposite Chen; Chen, last in Shen-Zi-Chen, is opposite Xu; Chou is opposite Wei; Wei is opposite Chou. Remember that and you don't need the table.

Counting it year by year

Take someone born in 2001, a Xin Si year. Si belongs to Si-You-Chou, so age 1 is in Wei. A woman moves backward and a man forward, going round every twelve years:

At 13 it's back in Wei, and again at 25 and 37, repeating every twelve years. On a Xingge chart, each palace shows the traditional ages at which your Minor Luck reaches it.

Traditional age

Minor Luck uses traditional age: you're 1 at birth and add a year at each lunar new year, not on your birthday. So between the lunar new year and your birthday each year, your traditional age is two more than your Western age. Someone born in 2001, for example, is 26 by traditional age from the 2026 lunar new year on, whether or not their birthday has passed.

Read Minor Luck with Annual Luck

Volume three of the Quan Shu, on the two luck periods and Tai Sui, says to look first at the Decade Luck, Minor Luck and Tai Sui (Annual Luck) each on its own, then at how they meet:

Examine how the Decade Luck fares on its own, how the Minor Luck fares on its own, and how Tai Sui fares on its own.

In practice:

• Minor Luck and Annual Luck in the same palace: that palace's matters feel especially present this year.
• In different palaces: read the two together, the Annual Luck for the wider setting and the Minor Luck for where you are at this age.
• Minor Luck and Decade Luck in the same palace: this year sits right on the decade's theme, and that palace's matters are especially concentrated.

Why a man's Minor Luck never meets the Annual Luck

The Annual Luck moves one palace forward each year, and a man's Minor Luck also moves one palace forward, so the two move in step and their distance never changes over a lifetime. A woman's Minor Luck moves the other way and meets the Annual Luck in the same palace once every six years. The distance depends only on the birth-year branch:

So a man's Minor Luck is always two palaces ahead, two behind or directly opposite the Annual Luck, and never overlaps it. The woman born in 2001 above has her Minor Luck and Annual Luck both in Wu at age 2, then again at 8, 14, 20 and 26.

Working through an example

Say a man was born in 1990, a Geng Wu year, with a Fire 6 Bureau and his Life Palace in Chou, his Decade Luck moving forward. In 2026 he is 37 by traditional age:

• Minor Luck: Wu belongs to Yin-Wu-Xu, so age 1 is in Chen; moving forward, he's back in Chen at 13, 25 and 37. Chen is his natal Property Palace.
• Annual Luck: the 2026 Bing Wu year is in Wu, his Friends Palace. The Minor Luck is two behind the Annual Luck, matching the table.
• Decade Luck: his 36–45 decade is also in Chen, held by Qi Sha.

This year the Minor and Decade Luck share a palace, exactly what the Quan Shu calls the Decade and Minor Luck meeting. Home, where he lives and what he builds up are the decade's theme, and at 37 that theme is especially concentrated; with the Annual Luck in the Friends Palace, outside events tend to come in through friends and colleagues.

How much weight Minor Luck carries

Schools weigh Minor Luck differently. Some modern schools look almost only at the Annual Luck, while the Quan Shu often pairs the Decade and Minor Luck as "the two luck periods." Volume one even uses the two to show scale when it talks about Hua Ji:

Met in the Minor Luck, a year falls short; in the Decade Luck, ten years of regret.

The same Hua Ji is a one-year matter in the Minor Luck and a ten-year matter in the Decade Luck. Volume three's section on the Southern and Northern Dipper also splits the year in two: Northern Dipper stars show in the first half of the Minor Luck year, Southern Dipper stars in the second half; the Decade Luck page has the table of which stars are which.

The palace the Minor Luck reaches is the "Minor Life Palace," and from it you can lay out Minor Siblings, Minor Spouse, Minor Wealth and so on, a full ring of twelve like the Annual Luck. It's read the same way: the Minor Life Palace's main stars, which natal palace it is, and its San Fang Si Zheng.

Xingge marks both the Minor and Annual Luck so you can compare for yourself. The practical approach: read the Decade and Annual Luck first, treat the Minor Luck as a supplement, and pay special attention to the years when it lands on the same palace as the Annual Luck. Some schools also take the stem of the Minor Luck palace for another set of transformations; beginners can leave that aside.

Minor, Annual and Decade Luck compared

Childhood luck

For the early years before the first Decade Luck begins, the classics have a separate "childhood luck." Volume two says:

One, the Life Palace; two, Wealth; three, Health; four, Spouse; five, Fortune; six, Career.

Age one looks at the Life Palace, age two at the Wealth Palace, age three at the Health Palace, and so on. Beginners don't need to memorize it; it's enough to know it exists.

The full lesson is Minor Luck and monthly luck, which also covers monthly luck and the Dou Jun. After you draw your chart, check whether this year's Minor Luck and Annual Luck are in the same palace.
