Heavenly Stems Mutual Conquest: Jiǎ-Yǐ Wood conquers Wù-Jǐ Earth → Wù-Jǐ Earth conquers Rén-Guǐ Water → Rén-Guǐ Water conquers Bǐng-Dīng Fire → Bǐng-Dīng Fire conquers Gēng-Xīn Metal → Gēng-Xīn Metal conquers Jiǎ-Yǐ Wood.

The mutual generation, conquest, and union relationships among Heavenly Stems determine the interactions among the Heavenly Stems within a BaZi chart—they form the basis for analyzing the activating relationships among chart stems. ---
