《北齐书·列传·卷五十》
陈德信从驿道兼程去检查，发现孝言派工匠为自己营造宅院，就对他说： 仆射替皇上起造宫殿还没有完工，为什么先替自己造屋呢? 韩凤和穆提婆也让孝言分派工匠为自己修造房宅，德信回朝禀奏了皇上。
陈德信驰驿检行，见孝言役官夫匠自营宅，即语云： 仆射为至尊起台殿未讫，何容先自营造？ 凤及穆提婆亦遣孝言分工匠为己造宅，德信还具奏闻。
Chen Dexin inspected the road post station along the way, and discovered that Xiaoyan had sent craftsmen to build a house for himself; therefore, he said to him: The Shushe has not finished building the palace for the emperor; why are you building a house for yourself first? Han Feng and Mutibo also had Xiaoyan send craftsmen to build houses for themselves. Dexin returned to court and reported this to the emperor.
