《北史·列传·卷二十六》
七岁时还不会说话，后来，在洛城上空看见群鸟遮天蔽日从西边飞来，才举手指着群鸟说了话。他聪明慧敏，与一般的儿童大不一样。十三岁，父亲去世，哀痛悲苦，和成年人一样。
少有志节，好直言。文宣末年昏纵，朝臣罕有言者。
At the age of seven, he still couldn't speak. Later, he saw a group of birds flying in from the west and blocking out the sky in Luocheng. Only then did he raise his finger, pointing at the birds, and speak. He was intelligent and lively, very different from other children. At the age of thirteen, his father passed away. He grieved and was as sorrowful as an adult.
