Wu Gui in Eastern Numerology: What 18 and 81 Mean
In Eight Mansions feng shui, Wu Gui is the Lian Zhen star. Eastern Numerology reads it as a fast mind, plenty of ideas and frequent change, linked to creative and planning work. This page covers the eight pairs of Wu Gui and their strength, its place in the Eight Mansions, the traditional reading, and how it interacts with the other stars.
The eight pairs of Wu Gui
Wu Gui has eight pairs. Common tables rank them into four strength levels, two pairs each; the two pairs on a level are the same digits in reverse order (for example 18 and 81) and carry the same weight.
| Strength level | Pairs | Trigrams (directions) |
|---|---|---|
| Level 1 | 18, 81 | Kan–Gen (north–northeast) |
| Level 2 | 79, 97 | Dui–Li (west–south) |
| Level 3 | 36, 63 | Zhen–Qian (east–northwest) |
| Level 4 | 24, 42 | Kun–Xun (southwest–southeast) |
Each digit in a pair is a Lo Shu number tied to one trigram. Matching the two trigrams by the Eight Mansions “Great Wandering Year” method gives Wu Gui, which is why Wu Gui is always exactly these eight pairs.

Wu Gui in the Eight Mansions
In Eight Mansions feng shui, Wu Gui is the Lian Zhen star. Eastern Numerology reads it as a fast mind, plenty of ideas and frequent change, linked to creative and planning work.
In the Eight Mansions system, Wu Gui is one of the eight directions, matched to the nine-star name Lian Zhen (Chastity), and one of the four unfavorable stars. Eight Mansions reads directions for people and houses; Eastern Numerology borrowed the same pairing to read numbers. The two share star names, but each developed its own readings.

How Wu Gui works with the other stars
The rhyme says “Sheng Qi + Tian Yi + Yan Nian settle Wu Gui,” in that order: all three favorable stars (Sheng Qi, Tian Yi and Yan Nian) are needed. That makes Wu Gui the hardest of the four unfavorable stars to balance.
When Wu Gui is followed by Fu Wei (for example 188), the Fu Wei carries Wu Gui forward, which amounts to one more Wu Gui pair.
