Meaning & origin

Guyu (Grain Rain) is one of the 24 solar terms (jieqi) used in the Korean Saju and East Asian lunisolar calendar. This page explains its meaning, the dominant 5-element flow, and how to use it when reading your Korean four-pillar fortune.

Guyu (Grain Rain) marks the rains that grow grain — Earth chi (Chen, late Yin-Wood transitions) absorbs spring's residue. Practical Saju use: stabilize ongoing projects; do not start brand-new launches in the last 10 days of Chen.

5-element flow

Earth (土) represents centering, stability, and transition between seasons. Under an Earth-dominant solar term, the chi grounds — consolidation, contracts, and real-estate-type stability moves are favored. In Saju, Earth controls Water (officer), is controlled by Wood (officer-receiver), produces Metal (output), is produced by Fire (resource). Practical use: integrate scattered work, close inventory, sign property/long-term contracts, stabilize routines.
