《世说新语·赏誉》
卫伯玉任尚书令时，看见乐广和西晋的名士清谈，认为他不寻常，说道： 自从当年那些名士逝世到现在，常常怕清谈快要绝迹，今天竟然从您这里听到这种清谈了！ 
卫伯玉为尚书令，见乐广与中朝名士谈议，奇之曰： 自昔诸人没已来，常恐微言将绝。今乃复闻斯言于君矣！ 
When Wei Boyu was the Minister of the Ministry of Officials, he saw Yue Guang and some famous scholars of the Western Jin Dynasty having a polite conversation, and thought that he was no ordinary person, so he said: Ever since those famous scholars passed away, I have always been afraid that polite conversation would disappear. I didn't expect to hear such a conversation from you today!
