Indirect Resource (PianYin 偏印) in BaZi

Indirect Resource is number 9 of the ten gods, in the Resource group — generating the day master. This is the god-level overview (no pillar attached): the two-step derivation, which stem carries it for each of the ten day masters, and which branch main qi land on it. All rows are computed and can be back-substituted. For what it means on a specific pillar, use the three pillar pages below.

The two-step derivation (published)

Assigning Indirect Resource takes exactly two steps, and both can be verified on the page:

Step one · the groupThe relation between the day master element and the target element sets the group: Indirect Resource belongs to the Resource group — generating the day master
Step two · which of the pairWithin the pair, Indirect Resource takes the stem whose polarity matches the day master
Pair structureIndirect Resource and Direct Resource share one group and one generating/controlling relation; polarity is their only difference — which is why the ten gods come in five pairs
What the pillar changesThe god does not change with position; the Indirect Resource pages for the year, month and hour pillars differ in the palace they describe, not in the derivation

Which stem gives it for each of the ten day masters

For a fixed day master the ten stems take the ten gods exactly once each, so which stem forms Indirect Resource is definite. All ten rows are computed — back-substitute any row and you get Indirect Resource.

Which branch main qi land on it

Each of the twelve branches has one main-qi stem (the first hidden stem). Among the ten stems, Wu and Ji appear twice (Chen-Xu, Chou-Wei) and the other eight once — so for any day master each god takes at least one branch and the twelve branches split exactly. The table lists the branches whose main qi form Indirect Resource for each day master.

A note on what this page deliberately does not do: the popular versions of this material assign a fixed personality to each term — one character per branch, one destiny per stage. This site rejects that framing. What is published here is a structural position: which element sits where, on what kind of ground, with which tenants inside. The same term reads differently under a different month command, and no meaningful judgement exists without the other characters of the chart. Where the tradition offers a reading it is labelled as the tradition's; this site's own contribution is that every number and term on this page is computed, versioned and checkable against the methodology page.

Frequently asked

What is Indirect Resource in bazi?
Indirect Resource (偏印) is one of the ten gods, in the Resource group — generating the day master. The derivation has two steps: the generating or controlling relation between the day master element and the target element sets the group, then polarity picks between the two gods in that group. It takes the stem whose polarity matches the day master.
Which stem is Indirect Resource for a 甲 day master?
壬 (Ren). The 甲 day master is 阳 Wood; 壬 stands in the relation of generating the day master with matching polarity, which is exactly the definition of Indirect Resource. The other nine day masters are in the table, each row back-substitutable.
What is the difference between Indirect Resource and Direct Resource?
Same group, same generating or controlling relation; the only difference is polarity: Indirect Resource takes the matching polarity, Direct Resource the opposite one. For any day master the two are carried by two different stems, and their main-qi branches never overlap.
Is a strong Indirect Resource good or bad?
A god is not a good-or-bad label, and this page gives derivation facts only. The same god often acts in opposite directions when the day master is weak versus strong; judging needs the month command, rooting, transparency and the whole chart. Any claim that more of a god is simply good or bad oversimplifies past what the system claims.
