Siblings Palace

The Siblings Palace, Xiong Di Gong, reads brothers and sisters specifically, their number, the closeness or distance of that relationship, and by extension in some lineages of practice a wider circle of close blood relatives of the native's own generation, a domain the tradition treats as distinct in kind from the chosen, non blood relationships read instead in the Friends Palace across the wheel. This distinction between blood and chosen relationship, kept as two entirely separate palaces rather than folded into one broader reading of companionship, reflects a wider emphasis in traditional Chinese family thought on lineage and blood tie as categories carrying weight independent of personal closeness or affection, a family member could be read favourably or unfavourably by this palace regardless of how warmly the native actually regarded them in practice.

Which of the fourteen major stars falls into the Siblings Palace is read as colouring the general tenor of that sibling relationship, a star such as Tian Tong favouring an easy, low conflict bond and a star such as Qi Sha suggesting a more contentious or distant one, though the tradition is careful to treat this as a reading of pattern and tendency rather than a fixed, unchangeable prediction about any specific sibling.

The Siblings Palace sits second in the twelve palace wheel's fixed order and stands directly opposite the Friends Palace, six positions further around the circle, a structural pairing that sets blood relation against chosen relation as two halves of the same underlying axis of companionship and mutual support rather than as unrelated domains. Practitioners reading a chart's Siblings Palace routinely check the Friends Palace opposite it as a matter of course, since the tradition holds that a native strongly favoured in one domain of companionship often shows a corresponding pattern, whether compensating or reinforcing, in the other, blood family and chosen circle read together rather than in isolation.

Ho Peng Yoke's account of the twelve palace structure notes that this pairing of blood and chosen relationship across the wheel is one of several oppositions in the system that read as genuinely complementary rather than as simple contraries, unlike, for instance, the Wealth and Fortune pairing, which sets material accumulation against a more inward, dispositional kind of fortune. A native whose Siblings Palace carries no major star of its own borrows a reading from the Friends Palace directly opposite it, the same empty palace convention that applies uniformly across all twelve of the wheel's positions.
