Reveal your Driver and Conductor numbers, your missing numbers, active planes and arrows — plus the traditional Feng Shui remedies for each gap.
Map Your Grid
Enter your birth date. Every digit 1–9 will be placed into its fixed position on the 3×3 magic square. Missing positions reveal where Feng Shui remedies are most needed.

The Lo Shu Grid is inseparable from Feng Shui. Each number governs a compass direction, an element, a planet and a life aspect. Use this table to enrich any reading.
Five Thousand Years in a 3×3 Square
According to the classic legend, a divine turtle emerged from the Lo River bearing a pattern of dots etched into its shell: 1 at the bottom, 9 at the top, 5 in the centre, and the remaining numbers arranged so that every row, column and diagonal summed to 15. Emperor Yu (great-grandson of the Yellow Emperor) saw in this the cosmic blueprint of harmony — a map of how energy flows through space and time. From this pattern Chinese scholars developed the foundations of Feng Shui, the I Ching, Chinese medicine and numerology.
Frequently Asked Questions
The Lo Shu Grid is a 3×3 magic square from ancient Chinese numerology. According to legend, Emperor Yu discovered it on the shell of a divine turtle emerging from the Lo River around 2800 BC. Every row, column and diagonal sums to 15 — a pattern considered the cosmic blueprint of balance.
We take each digit of your full birth date (day, month, year), place every non-zero digit into its fixed position on the 3×3 grid, and also add your Driver Number (day reduced to a single digit) and Conductor Number (full date reduced). Missing positions reveal life areas to strengthen; repeated digits show amplified themes.
The Driver Number comes from the day of birth alone and describes your inner nature — how you approach life day to day. The Conductor Number comes from the entire birth date and describes your life path — the broader journey you are here to walk. Together they form the core of your Lo Shu reading.
A missing number indicates a life area where growth is needed. For example, a missing 1 suggests work on communication and career direction; a missing 6 points to domestic harmony. Each missing number comes with a traditional Feng Shui remedy — colours, objects and directions to bring that energy into your space.
Planes and arrows are straight lines on the grid — three horizontal planes (Mental, Emotional, Practical), three vertical arrows (Thought, Will Power, Action) and two diagonal Success Arrows (Golden, Silver). A fully present plane gives you its complete positive expression; a partial or missing plane reveals where development is needed.
No — zeros are omitted when filling the grid. Only digits 1–9 are placed, since the grid itself contains positions 1–9. This is why someone born on, say, 10 October 2000 may have a sparser grid than someone born on 28 September 1987.
The 3×3 grid directly maps to the eight compass directions plus the centre. Each number governs a direction, an element (Wood, Fire, Earth, Metal, Water) and a life aspect. When you know which numbers are weak or missing, you know which sectors of your home or office need Feng Shui support.
Yes. Two grids can be overlaid to find shared strengths (numbers you both have), complementary strengths (where one person covers the other’s missing number) and blind spots (numbers missing in both charts). Strong relationships usually feature many complementary numbers — each partner balancing the other.
They share the same 1–9 planetary framework but use very different grids. Vedic (Anka Shastra) builds a similar numerical chart, yet Lo Shu uniquely fixes the numbers into a 3×3 magic square tied to compass directions and Feng Shui. Many modern numerologists use both side by side for a complete picture.
The Lo Shu is the world’s oldest known magic square. The constant 15 is the magic sum: rows, columns and diagonals all add to 15. This property made the square sacred in Chinese philosophy — it represented perfect balance between heaven, earth and human action.
