《新唐书·列传·卷六十四》
房琯劝谏道 ：过去杨国忠搜刮盘剥，使天下人怨恨；皇上登基人们没见德政，现又宠信第五琦，这是一个杨国忠死了，另一个杨国忠又产生了，不能让全国人民安心。 
琯谏曰： 往杨国忠聚敛，产怨天下。陛下即位，人未见德，今又宠琦，是一国忠死，一国忠生，无以示远方。 
Fang Guan advised: "In the past, Yang Guozhong's exploitation and exploitation made the people of the world resentful. The emperor has not seen any good governance after his accession to the throne, but now he favors Wu Diqi. This means that one Yang Guozhong has died and another one has emerged. We can't let the people of the whole country rest assured."
