《旧唐书·列传·卷七十九》
我在荆南、剑南时，管辖的州县有官员缺额的，不下十多年，吏部没有补派，只命一个官员代理，政事也处理好了。
臣在荆南、剑南，所管州县阙官员者，少不下十数年，吏部未尝补授，但令一官假摄，公事亦理。
When I was in Jingnan and Jiannan, there were shortages of officials in the prefectures and counties under my jurisdiction for more than ten years, and the Ministry of Personnel did not send replacements, but simply appointed one official to act for several, and the affairs of government were still carried out properly.
