《南齐书·志·卷九》
辛日既然是常规的郊祭之曰，郊祭又在明堂祭祀之前，不容许不郊祭而祭祀明堂，理应是郊祭明堂祭祀都举行。 
辛既是常郊之日，郊又在明堂之前，无容不郊而堂，则理应郊堂。 
As Xin is a normal day for sacrifices, and as it is before the sacrifices at the Mingtang, the rules do not permit sacrifices to be offered at the Mingtang without them also being offered at the sacrifices in the outdoors.
