Lo Shu Magic Square

洛書 — The mathematical heart of feng shui.

Legend says a turtle emerged from the Lo River carrying this pattern on its shell. The 3x3 grid where every row, column, and diagonal sums to 15 became the foundation of Flying Stars feng shui. The stars fly through the Lo Shu in a specific sequence — this is how natal charts are calculated.
