BaZi · Twelve Earthly Branches
The seasonal cycle beneath every pillar
A stem appears above while a branch carries season, double-hour, and a fixed Hidden Stems list. The twelve branches are not twelve personality types; they are the other half of the Four Pillars coordinate.
This library explains fixed structure only. It adds no Hidden Stem weights, roots, strength, combinations, transformations, or event predictions.Season map
Each season has an opening, centre, and transition
