Ba Zi/Heavenly Stems

Heavenly Stems There are ten Heavenly Stems (represented by the acronyms "H" or "HS") used in the construction of the Four Pillars of Ba Zi (四柱八字), a method of Chinese Divination based on a person's date and time of birth. For example, both the acronyms "HS1" and "H1" represent the first Heavenly Stem, namely "Jia" (Yang Wood), as shown in the tables below.

These combinations result in a good structure of a person's Ba Zi "Clash" means that the Heavenly Stems clash with each other in the Ba Zi, when they are next to each other. Clashes will result in a poor structure of a person's Ba Zi. If there is a Clash of two adjacent Stems, as well as a Combination with another Stem, the Clash will not occur, as Combinations take precedence over Clashes.
