Tian Fu (Tiānfú): the Lu of the official star
Save share card ↓

Tian Fu follows the birth-year stem: find the official star that controls it, then take that star's Lu. The method in juan 5 of the Sanming Tonghui matches the engine for all ten stems. A flow, a table, sample charts.

The short version7 min read

Two different stars are spelled Tian Fu in pinyin, and only the tone separates them. This one, the adjective star Tian Fu (天福, Tiānfú), takes the Lu of the official star: find the stem that controls the year stem, then see which branch holds that stem's Lu.

  • The rule has two steps: find the official star (the stem of opposite polarity that controls the year stem), then take its Lu position; the entry on the heavenly blessing noble in juan 5 of the Sanming Tonghui describes exactly this.
  • All ten year stems were checked against the engine and every one agrees; only eight branches occur, and Dragon, Dog, Ox and Goat, the four storage branches, never do.
  • Tian Fu (天福, Tiānfú) and the major star Tian Fu (天府, Tiānfǔ) differ by one tone: one is an adjective star and the other a major star.
Eighteen seconds on Tian Fu: how a Yang Wood year goes from official star to Lu, why ten stems give eight landing points with all four storage branches empty, and three questions to ask before reading.

Three steps: year stem, official star, its Lu

Tian Fu (天福) takes the Lu position of the official star: find the stem that controls the year stem, then see which branch holds that stem's Lu.

A three-row flow: a Yang Wood year has Yin Metal as official star, whose Lu is on Rooster, so Tian Fu is on Rooster; a Yin Earth year has Yang Wood, whose Lu is on Tiger, so Tian Fu is on Tiger; a Yang Water year has Yin Earth, whose Lu is on Horse, so Tian Fu is on Horse. Each row has four steps: year stem, official star, its Lu, Tian Fu.Open the full-size diagram

Flow sketch: the official star is the stem of opposite polarity that controls the year stem; its Lu follows the usual ten-stem Lu table, after the method in the entry on the heavenly blessing noble in juan 5 of the Sanming Tonghui, and agrees with the engine for all ten stems.

Two terms first. A stem's official star is the one stem of opposite polarity that controls it; the first column of the table below lists all ten. A stem's Lu is the branch where it reaches the Establishment stage (临官) of the twelve life stages, and the second column gives the Lu of each official star. The blessing-noble entry in the fifth juan of the Sanming Tonghui (三命通会) states the method plainly:

It means that where the official star sits it meets its Lu, like a person who holds office and draws a stipend, which is a blessing from heaven. A person of Yang Wood takes Yin Metal as the official; Yin Metal has its Lu on Rooster, hence Yang Wood meets Rooster, and Yin Wood meets Monkey by the same reasoning.

Sanming Tonghui, the blessing-noble entry in juan 5, our translation

The book works two examples: the official star of Yang Wood is Yin Metal, whose Lu is on Rooster, so Yang Wood gets Rooster; the official star of Yin Wood is Yang Metal, whose Lu is on Monkey, so Yin Wood gets Monkey. Run all ten stems through the same method and compare with the engine's table, entry by entry:

A ten-row, three-column table: for each year stem its official star, the branch of that star's Lu and the engine's Tian Fu, which are the same in every row: Yang Wood Yin Metal Rooster, Yin Wood Yang Metal Monkey, Yang Fire Yin Water Rat, Yin Fire Yang Water Pig, Yang Earth Yin Wood Rabbit, Yin Earth Yang Wood Tiger, Yang Metal Yin Fire Horse, Yin Metal Yang Fire Snake, Yang Water Yin Earth Horse, Yin Water Yang Earth Snake.

All ten rows agree, and none needs an "exception" to explain it.

Tian Fu the adjective star, Tian Fu the major star

The pinyin of the two stars differs by one tone, yet the characters are different. Side by side:

The major star Tiānfǔ (天府) is placed from Zi Wei and appears once per chart; the adjective star Tiānfú (天福) is placed by the year stem and takes the Lu of the official star.

The major star is covered in the article on Tian Fu (天府). In your own notes, whenever you write Tian Fu (天福), say that it is the adjective star looked up by the year stem, rather than relying on the pinyin.

One official star, two spots: Tian Guan and Tian Fu

In the Sanming Tonghui, Tian Fu and Tian Guan both start from the official star, but they do different things with it. For a Yang Wood year the official star is Yin Metal: Tian Guan takes the branch where Yin Metal turns up inside the decade, Goat (Yin Metal over Goat), and Tian Fu takes the branch of Yin Metal's Lu, Rooster:

A ring of twelve branches: in a Yang Wood year the official star is Yin Metal; Tian Guan lands on Goat, where Yin Metal turns up in the decade, and Tian Fu on Rooster, the Lu of Yin Metal, two places apart.

One official star, two landing points. Another example is a Yin Wood year: the official star is Yang Metal, Tian Guan is on Dragon (Yang Metal over Dragon) and Tian Fu on Monkey, the Lu of Yang Metal. Only in a Yang Earth year do the two stars fall on the same branch, the Rabbit: the Tian Guan table gives Rabbit for Yang Earth, and Tian Fu takes the Lu of the official star, Yin Wood, which is also on Rabbit.

Palace names on four charts

Once the branch is known, the palace name is counted from Life. Four charts, three stems, and in three of them Tian Fu is on Horse:

Four sample charts: a Geng-Wu year with Life on Rat, Tian Fu on Horse, the Travel palace; a Ren-Zi year with Life on Tiger, Tian Fu on Horse, the Career palace; a Geng-Yin year with Life on Rabbit, Tian Fu on Horse, the Property palace; a Wu-Chen year with Life on Ox, Tian Guan and Tian Fu both on Rabbit, the Wellbeing palace.

Tian Fu is on Horse in all three charts, in the Travel, Career and Property palaces. The same branch does not mean the same palace: the palace name depends on the Life palace.

  1. Step one: the official star

    With the year stem fixed, read its official star off the first column of the table.

  2. Step two: its Lu

    The Lu of the official star is the branch of Tian Fu; it is bound to be among the eight landing branches.

  3. Step three: the palace

    Put that branch back on the chart, count to it from Life and read the name.

Two quick questions

Question one

Born in a Yin Wood year: which branch holds Tian Fu?

The official star of Yin Wood is Yang Metal, whose Lu is on Monkey, so Tian Fu is on Monkey; counting from Life to that branch then gives the name.

Question two

Why does no stem put Tian Fu on Ox or Goat?

Ox and Goat are storage branches and nobody's Lu; Tian Fu only ever takes a Lu position, so it cannot land on them.

Another adjective star looked up by year stem is Tian Guan; for how the year stem also drives the four transformations, read the birth-year four transformations.

Questions readers ask next

Are Tian Fu (天福) and Tian Fu (天府) the same star?

No. The major star Tian Fu (天府) is one of the fourteen major stars and its position follows from Zi Wei; the adjective star Tian Fu (天福) is looked up by the year stem. The pinyin differs only in the tone, so be careful with the characters when writing notes.

Why are Yang Metal and Yang Water years both on Horse?

The official star of Yang Metal is Yin Fire and that of Yang Water is Yin Earth, and the Lu of both Yin Fire and Yin Earth is on Horse. In the same way the official stars of Yin Metal and Yin Water, Yang Fire and Yang Earth, have their Lu on Snake, so ten stems give only eight landing points.

Tian Fu and Tian Guan both start from the official star; why do they land differently?

In the Sanming Tonghui's account, Tian Guan takes the branch where the official star turns up when hidden inside the stem's own decade, and Tian Fu takes the branch of the official star's Lu, so the two moves differ. For a Yang Wood year the official star is Yin Metal: Tian Guan is on Goat and Tian Fu on Rooster, the Lu of Yin Metal.
