Registrars of the Left and Right Streets (The Left and Right Streets originally arose when the Commissioners of Merits were established and [monasteries] were subordinated to them. When the Buddhist Registrars were established, they also used the Left and Right Streets. Monks were assigned Registrars to record them, and the Commissioners of Merits each governed them separately.)
