Sibling Stars in Bazi (兄弟姊妹星)
Use Companion and Rob Wealth as conditional sibling-role symbols, then check pillar context and avoid counting or profiling real siblings.
Overview
Sibling Stars usually refer to the Companion and Rob Wealth families because both share the Day Master’s Five Phase. This describes a peer-level symbolic relationship, not a literal sibling count or a fixed rule for closeness and rivalry. A reading must identify each occurrence, polarity, strength, pillar, relations, and school convention, then compare the symbols with the relevant palace and the user’s actual family structure.

Derive peer-role stars from the Day Master
Companion and Rob Wealth are the same Five Phase as the Day Master, separated by yin-yang polarity. Family-role tables commonly extend this peer relation to siblings.
The technical names do not establish whether a real sibling is similar, competitive, generous, dependent, older, younger, male, or female.
- Calculate both Ten Gods exactly.
- Do not literalize the English labels.
Assess occurrences instead of counting siblings
List each visible and hidden occurrence with its pillar, root links, season, support, control, combinations, and clashes before describing the peer function.
Multiple occurrences can reflect one distributed chart function; absence can still coexist with siblings and active peer relationships.
- Separate visible and hidden evidence.
- Never convert frequency into family size.
Use palace context without collapsing the evidence
Some schools emphasize the Month Pillar or another declared family palace when discussing siblings. Preserve that positional convention separately from the Ten-God map.
If star and palace evidence diverge, report the divergence instead of forcing a story about closeness, conflict, support, inheritance, or money.
- State the palace convention.
- Publish supporting and contrary evidence.
Do not profile siblings who are not the client
Sibling Stars cannot reveal a sibling’s identity, gender, health, finances, fertility, loyalty, criminality, intentions, or future events.
Use direct communication, consent, records, and professional support for disputes, caregiving, estates, safety, or financial arrangements.
- Protect third-party privacy.
- Use real evidence for consequential choices.
