Sitting opposite the Health palace (疾厄宮), this configuration occupies the Health–Parents (疾厄–父母線) and reads against inherited lineage alongside the constitutional body: Children · Friends · Parents · Health. Qi Sha does not undergo the Four Transformations directly — expression decided by company.
Where Qi Sha sits in 父母宮, the register typically reads through parental relationships and the recurring pattern with mentors, teachers, regulators — though the specific intensity depends heavily on supporting stars.
At textbook level, the configuration tends to produce founders, military officers, surgeons, athletes in contact sports, leaders of irreversible high-stakes ventures, with the parental relationships and the recurring pattern with mentors, teachers, regulators taking on decisive action. Qi Sha’s characteristic risk — decisive action that becomes self-destructive when the Four Killings sit in or oppose the palace — surfaces specifically through parents and authority figures when supporting conditions are absent. Pairings with Wu Qu reinforce this picture; pairings with the Four Killings (擎羊, 陀羅, 火星, 鈴星) sharing or opposing the palace can flip it.
Practitioners reading at depth weigh four further layers that this reference does not develop: which auxiliary stars (左輔, 右弼, 文昌, 文曲, 天魁, 天鉞) share or oppose the palace, whether any of the Four Killings (擎羊, 陀羅, 火星, 鈴星) sit in the same or opposing palace, whether self-transformations (自化) on adjacent palaces alter the configuration’s energy, and how the current 10-year and annual luck cycles activate or suppress what sits in the Parents Palace and the opposing Health Palace. Synthesising these layers across a real chart is the practitioner skill the Zi Wei Dou Shu Masterclass teaches.
