Luban Ruler (鲁班尺) — very important in Feng Shui. Since you’re in Singapore, many contractors still secretly use it for doors, altars, counters, cash registers, etc.
There are two common Luban rulers:
-
Yang House Luban Ruler (for houses, doors, furniture)
-
Yin House Luban Ruler (for tombs / graves)
For homes and business, we use the Yang House ruler (42.9 cm cycle).
📏 How Luban Ruler Works (Simple Explanation)
Every 42.9 cm is one full luck cycle.
Inside each cycle, there are 8 sections:
-
财 (Wealth) ✅
-
病 (Illness) ❌
-
离 (Separation) ❌
-
义 (Righteousness / Noble help) ✅
-
官 (Authority / Career) ✅
-
劫 (Loss) ❌
-
害 (Harm) ❌
-
本 (Stability / Foundation) ✅
Good sections:
-
财 (Wealth)
-
义 (Noble support)
-
官 (Career luck)
-
本 (Stability)
Bad sections:
Then the cycle repeats every 42.9 cm.

⚠️ Important Rule
It’s NOT just about the number like 88 or 168.
The exact measurement must fall inside a GOOD Luban section, not just “nice sounding number”.
Example:
-
88 cm might be lucky in general Chinese culture
-
But if it falls inside a “Illness” section on Luban, it’s NOT good
That’s why professional Feng Shui masters use a real Luban ruler.
