History · 史记
Gouchen — the Hook-Array — is a constellation near the pole that ancient astronomers assigned to military affairs: Sima Qian's Tianguan Shu records that it governs the six armies. As a deity, Gouchen Dadi is the sovereign of war and the balancing weight of the celestial bureaucracy, often described as the elder brother of Ziwei Dadi.
Where Ziwei holds the still center, Gouchen commands its movement — campaigns, borders, and the martial force that keeps heaven's order intact. Imperial dynasties included him in their state sacrifices of war.

In the liturgy Gouchen Dadi stands between the star-vault of Ziwei and the earth of Houtu — the hinge that keeps celestial command and terrestrial obedience turning together.
