《旧唐书·本纪·卷十九》
这个地区管辖下的八个州郡没有耕织的习惯，地方又极其边远，近来遭到盗贼骚扰，更加凋敝衰落。
其所管八州，俗无耕桑，地极边远，近罹盗扰，尤甚凋残。
The eight prefectures and counties governed by this circuit did not engage in farming or weaving, and the land was extremely remote. Lately, with bandits running rampant, the area became even more poor and desolate.
