Hexagram Setup Rules & Walkthrough

Follow along step-by-step using the Ze Lei Sui hexagram as an example.

1

Identify the Upper and Lower Trigrams

The upper (outer) trigram is Dui ☱, and the lower (inner) trigram is Zhen ☳.

2

Assign the Heavenly Stems

Lower (inner) trigram Zhen mnemonic: Zhen (Wood): Geng-Zi inside, Geng-Wu outside
→ Inner Stem is Geng, governing Lines 1, 2, and 3.
Upper (outer) trigram Dui mnemonic: Dui (Metal): Ding-Si inside, Ding-Hai outside
→ Outer Stem is Ding, governing Lines 4, 5, and 6.

3

Assign the Earthly Branches

Lower (inner) trigram Zhen branches:
Zhen (Wood): Geng-Zi inside, Geng-Wu outside → Line 1 starts with Zi
• Line 1 = Zi
• Line 2 = Yin (skips Chou after Zi)
• Line 3 = Chen (skips Mao after Yin)
Upper (outer) trigram Dui branches:
Dui (Metal): Ding-Si inside, Ding-Hai outside → Line 4 starts with Si
• Line 4 = Hai (Si is 3rd in sequence)
• Line 5 = You (skips Xu after Hai)
• Line 6 = Wei (skips Shen after You)
