Yue Jie structure (月劫格)
How it was found
- 1The Day Master is 丁.
- 2Born in a 巳 month; the month branch hides 丙, 庚, 戊.
- 3The month's main qi 丙 is the Day Master's Rob Wealth; for a yin Day Master this is called Yue Jie.
- 4So the chart forms the Yue Jie structure (月劫格).
No strong helpers or breakers: a steady structure where luck pillars and years make the difference.

Ten gods combinations in your chart
- Peers seize the Wealth (比劫奪財) — Many Friend and Rob Wealth stars with weak Wealth: money and partners are taken by others. Output eases it.
- Output produces Wealth (食傷生財) — Eating God or Hurting Officer feeding Wealth: talent and skill turned into income.
The structure is taken from the month branch (Zi Ping Zhen Quan). Helpers and breakers count stems and branch main qi only; special structures (follow, dominant) need the whole chart.
About Rob WealthHow to read a Bazi structure, in four steps
The structure is a chart's skeleton. It is read from the month branch: whichever of its hidden stems shows on a heavenly stem names the structure. The structure sets the chart's theme; supporting and breaking factors decide how well it works.
- 1
Find the Day Master
The day pillar's stem is the Day Master; every ten god is read from it.
- 2
List the month's hidden stems
The month branch commands the chart. Write down its hidden stems: main, middle and residual qi.
- 3
See which one shows
The hidden stem that shows on the year, month or hour stem names the structure; if none shows, the main qi does. A month branch that is the Day Master's prosperity or Goat Blade gives the Jian Lu or Goat Blade structure.
- 4
Check helpers and breakers
Find the gods that support the structure and those that break it (Hurting Officer meeting the Officer, the owl stealing the food), then weigh the Day Master's strength.
Use directly or by restraint: four auspicious and four fierce structures
Wealth, Officer, Resource and Eating God are benign gods, used directly: feed and protect them. Seven Killings, Hurting Officer, the Owl and the Goat Blade are fierce gods, used by restraint: control and transform them. It is the first principle of reading structures.
財官印食，此用神之善而順用之者也；煞傷梟刃，此用神之不善而逆用之者也。Four auspicious (used directly)
Four fierce (used by restraint)

Special structures: follow and dominant
When the Day Master is extremely weak and the chart is all Wealth, Officer or Output, it may 'follow' that force (follow Wealth, Killings or Output). When it is extremely strong and the chart is all one family, it may form a dominant structure. These aren't taken from the month branch but from the whole chart, and the calculator here doesn't cover them.
