Quick Answer
The Peer star (比劫) is the element identical to your Day Master — same element, differing only by polarity. It splits into Friend (比肩) and Rob Wealth (劫财). Peer is the one group that reads in genuinely two directions: support for a weak Day Master, competition for a strong one.
This article explains a traditional framework for self-reflection. It is not business, legal or financial advice, and BaZi does not predict partnership or competitive outcomes.

1. What the Peer star is
Every Heavenly Stem in a BaZi chart relates to your Day Master in one of ten fixed ways — the Ten Gods. The Peer star is the group of the same element as the Day Master.
| Day Master | Peer element |
|---|---|
| Wood | Wood |
| Fire | Fire |
| Earth | Earth |
| Metal | Metal |
| Water | Water |
Peer is the only group whose element is not different from the Day Master in kind — only in polarity. Placed alongside the others:
| Group | Relationship | Direction |
|---|---|---|
| Wealth | Day Master controls it | Outward, to what you manage |
| Officer | It controls the Day Master | Inward, as constraint |
| Resource | It produces the Day Master | Inward, as support |
| Output | Day Master produces it | Outward, as production |
| Peer | Same as the Day Master | Parallel — alongside |
That parallel relationship is why Peer reads differently from every other group: it is not about something acting on you or coming from you, but about what shares your position.
2. Friend versus Rob Wealth
The split is polarity, and the two names describe two ways of sharing the same position.
| Friend (比肩) | Rob Wealth (劫财) | |
|---|---|---|
| Relationship to Day Master | Same element, same polarity | Same element, opposite polarity |
| Traditional reading | Steady alliance, self-reliance | Contested claim on the same resources |
| Classical associations | Siblings, colleagues, autonomy | Rivals, shared assets, impulsive spending |
Two clarifications:
First, "Rob Wealth" is not a character judgement. 劫财 describes a structural situation — a peer of opposite polarity competing for the same pool. It is a statement about structure, not about anyone's ethics.
Second, it is not "good friend versus bad friend." Both are peers. Polarity describes the nature of the sharing, not the moral quality of the people involved.
3. How polarity decides the label
Take a Jia Wood Day Master (Yang Wood). Wood is the Peer element. Wood appears in two stems:
| Stem | Element | Polarity | Relationship | Label |
|---|---|---|---|---|
| Jia Wood | Wood | Yang | Identical to Jia | Friend |
| Yi Wood | Wood | Yin | Same element, opposite polarity | Rob Wealth |
Switch the Day Master to Yi Wood (Yin Wood) and the same two stems flip: Jia Wood becomes Rob Wealth, Yi Wood becomes Friend.
The stem did not change. The Day Master did. Every Ten God label is relative to your Day Master — including, subtly, the Day Master's own element. For the elemental layer underneath, see the five elements in BaZi.
4. Why more Peer does not mean more allies
The number of Peer stars says how prominent the same-position theme is — how much of the chart is organised around peers, equals, shared claims and self-reliance. It does not say how many allies you have, or how well they serve you.
Peer is the group where the direction of the reading flips most completely with Day Master strength:
- Weak Day Master — the chart lacks support, and Peer is support. A same-element companion reinforces a light Day Master directly. Here Peer reads as reinforcement and self-reliance.
- Strong Day Master — the chart already has surplus. More same-element presence reinforces an already-saturated chart, and — crucially — competes for the same resources. Here Peer reads as contested claim.
So two people can each have three Peer stars with opposite readings, and for this group the swing is the widest of any. The count is not the reading — and here, the count is not even close to the reading.
5. The double nature unique to Peer: support and competition
Peer is the only group that is simultaneously the chart's reinforcement and its competitor, and both come from the same mechanism.
The reason is that Peer does two things at once:
| Structure | Relationship | Traditional reading |
|---|---|---|
| Peer reinforces Day Master | Peer → Day Master | Support, alliance, self-reliance |
| Peer competes for Wealth | Peer → controls Wealth | Shared claim on the same resources |
Both rows describe the same stars. A Peer stem standing next to your Day Master adds support and takes a share of whatever Wealth is present. That is why the traditional caution is never about Peer in the abstract — it is about Peer relative to Wealth.
When Wealth is strong and Peer is light, Peer reads as support with plenty to share. When Wealth is light and Peer is heavy, the classical description is a contested pool: more claimants than resource. Readings then turn to partnership structures, shared finances and spreading effort.
This is a structural observation about where a chart's claims sit. It is not a prediction about any specific relationship.
6. How Peer fits with the other groups
| Interaction | Structure | What it traditionally indicates |
|---|---|---|
| Peer controls Wealth | Peer → controls Wealth | Shared claim on resources |
| Officer controls Peer | Officer → controls Peer | Structure disciplining the peer group |
| Resource generates Peer | Resource → Peer | Support distributed across peers |
| Peer drains Output | Peer → drains Output | Peers drawing on the same outlet |
Officer controlling Peer is the classical corrective for a Peer-heavy chart: structure and duty imposing discipline on an otherwise unmanaged group of equals. It reads as the counterpart to the Officer reading in Officer star in BaZi.
Peer draining Output is a subtler interaction: when peers draw on the same expressive outlet, the traditional reading is competition for visibility rather than for resources — see Output star in BaZi.
Peer controlling Wealth is the relationship to check first in any Peer reading, and its Wealth-side description appears in Direct Wealth vs Indirect Wealth.
7. When the Luck Pillars bring Peer into focus
The Luck Pillars and annual pillar do not create or destroy Peer stars — they shift how prominent the theme is. For the mechanics, see the BaZi luck pillar explained.
- A Luck Pillar activating Peer tends to foreground peers, equals, collaboration and self-reliance — and, for a strong Day Master, competition for the same resources.
- For a weak Day Master that is often the useful direction. For a strong one, it can read as a period of contested claims.
- The annual pillar adds the finer layer: Heavenly Stem as the visible aspect, Earthly Branch as the materialising one.
A caution throughout: a period "activating Peer" describes where a chart's emphasis shifts. It does not forecast a partnership outcome, a dispute, or a financial result. Nothing here is business or financial advice.
8. Common questions about the Peer star
Does a Peer star mean I will have many friends?
No. That is the most common shortcut. Peer describes how same-position elements relate to your chart — it does not assert a number of allies.
Why is it called Rob Wealth?
It is a literal translation of 劫财. The name describes a structural situation — a same-element peer of opposite polarity competing for the same resource pool — not a moral judgement about anyone.
What if my chart has no Peer star?
It means the same-position theme is not structurally emphasised. Readers then look at the chart's favourable elements and at the Officer and Resource groups. An absent star is far less significant than the balance of what is present.
When is Peer helpful?
When the Day Master is weak. Peer is the one group whose benefit depends most directly on strength: a weak chart is reinforced by a same-element companion, while a strong chart is burdened by one. The determining factor is usually the ratio of Peer to Wealth.

FAQ
What is the Peer star in BaZi?
The Peer star is the group of Ten Gods whose element is the same as your Day Master, differing only in polarity. It represents peers, equals, self-reliance and shared claims.
What is the difference between Friend and Rob Wealth?
Both are the same element as your Day Master; they differ by polarity. Friend is the same polarity, Rob Wealth the opposite. The distinction describes the nature of the sharing, not the moral quality of the people.
How do I find my Peer star?
Identify your Day Master, then look for other Heavenly Stems of the same element. Those stems are Peer stars; compare polarity to tell Friend from Rob Wealth.
Does Peer predict partnership success?
No. BaZi is a traditional framework for self-reflection. It describes structural tendency and timing themes; it does not forecast partnership outcomes, disputes or financial results, and it is not business or legal advice.
Why is Peer both support and competition?
Because Peer does two things at once: a same-element stem reinforces the Day Master and competes for Wealth. Which reading dominates depends on the ratio of Peer to Wealth and on the Day Master's strength.
