43.24

In the fifth year [972], an imperial edict decreed concerning Buddhist monks and Daoist priests: Whenever attending court assemblies, monks are to take precedence and Daoists follow, standing together in the palace courtyard, monks on the east and Daoists on the west, interspersed with subordinate officials. When attending the sacrifice to Heaven in the suburbs, Daoists are on the left and monks on the right (Sengshi lüe).
