Lesson notes and examples

1. Primary, Relating and Palace

Record 7, 8, 6, 7, 8, 9 from bottom to top. Lines 3 and 6 change, giving hexagram 21, Biting Through, relating to 55, Abundance. Hexagram 21 belongs to Xun Wood in the eight-palace sequence; its upper trigram does not determine its palace.

2. Assign the Na Jia Branches

The site's table assigns Geng-Zi, Geng-Yin and Geng-Chen to the lower Zhen trigram, then Ji-You, Ji-Wei and Ji-Si to the upper Li trigram. Check lower and upper trigrams before reading each branch and element.

3. Locate Self and Other

Hexagram 21 is at the fifth-change position in Xun, placing Self at line 5 and Other at line 2, three positions apart. Palace order determines these markers; the question then determines which target to use.

4. Six Kin from Palace Relationships

Use the palace element as the reference. For Xun Wood, Water is Parents, Wood Peers, Fire Offspring, Earth Wealth and Metal Officer/Ghost. These labels classify roles in a question and need not describe literal relatives.

5. Assign the Six Spirits

Six Spirits begin at line 1 according to the day stem. Yi starts with Green Dragon, then Vermilion Bird, Gou Chen, Flying Serpent, White Tiger and Dark Warrior. An individual spirit marker alone does not establish a real event.

6. Question Target and Time Context

Focus on one question. The site uses Wealth for a money question, Officer/Ghost for a job question and Wealth for income. Month You and day Mao supply generating, controlling, clash and combination context; Zi and Chou are void. Months change at jie solar terms and days at local midnight.

Practice questions

Is Na Jia Liu Yao the same as selecting changing-line texts?

They can use the same cast values. Na Jia assigns stems, branches, Six Kin, Self/Other and Six Spirits, with month and day context. Textual readings select Zhouyi passages from the changing lines.

Does answering twelve questions establish an outcome?

The questions check chart construction and basic classification. A full reading also requires a focused question, target selection, strength and changing-line relationships.

How do mistakes and reviews work?

Missed questions return at the end and become due in ten minutes. Correct answers move to review intervals of one, three, seven days and longer. First-answer accuracy keeps the original result. You can return to due questions after completing the course.

Can I continue in the other language?
