BaZi Elements: How Heavenly Stems and Earthly Branches Shape You
The BaZi (八字) system is built on two interlocking systems: the Ten Heavenly Stems and the Twelve Earthly Branches. Understanding these building blocks is essential for reading any BaZi chart.
The Ten Heavenly Stems
Each Heavenly Stem combines one of the Five Elements with Yin or Yang energy:
The Twelve Earthly Branches
The Earthly Branches correspond to the 12 zodiac animals and carry their own elemental energies:
**子 (Zǐ, Rat)** — Water | **丑 (Chǒu, Ox)** — Earth
**寅 (Yín, Tiger)** — Wood | **卯 (Mǎo, Rabbit)** — Wood
**辰 (Chén, Dragon)** — Earth | **巳 (Sì, Snake)** — Fire
**午 (Wǔ, Horse)** — Fire | **未 (Wèi, Goat)** — Earth
**申 (Shēn, Monkey)** — Metal | **酉 (Yǒu, Rooster)** — Metal
**戌 (Xū, Dog)** — Earth | **亥 (Hài, Pig)** — Water
How They Work Together
Each pillar in your BaZi chart pairs a Heavenly Stem (the visible, conscious energy) with an Earthly Branch (the hidden, subconscious energy). The Stem shows your outer expression; the Branch reveals your inner nature.
