The Siblings Palace and Blood Relation

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.
