	Jiantai governs the gnomon, the water clock, and the affairs of pitch pipes and temperaments. Ganshi Zan (甘氏赞) says:

	Jiantai guards the water clock and the gnomon ~~– the extinguishing of the dripping~~.

	Gande (甘德) said: ~~“Jiantai~~ is in charge of the water clock, ~~the railings, the calendar,~~ calamities, ~~and~~ the ~~nine provinces~~ and their ~~fields~~.”

	Jiantai is also ~~“the~~ courtyard where ~~the ten thousand~~ essences gather.” Anomalies in different seasons correspond respectively to warfare (spring), funerals (summer), famine and floods (autumn), and banditry and punishments (winter).
