《太平广记·卷一百八十七·职官》
唐德宗贞元之后，专门设使，称为度支使，由郎官值班处理具体事务。其职事中最重要的是颁布皇帝的有关命令。

After Emperor Dezong of Tang's Zhenyuan reign, officers were specifically appointed to this role. These officers were known as the Ministry of Revenue Commissioners and would process day-to-day affairs. Their most important duty was to issue imperial orders.
