《北史·列传·卷三十九》
博士韩毅叫他写字，见他的笔体不工整，开玩笑对他说： 五郎写成这样的画，忽然被授予常侍开国，从今以后，应该更用心一些！ 
博士韩毅教浟书，见浟笔迹未工，戏浟曰： 五郎书画如此，忽为常侍开国，今日后，宜更用心！ 
The doctor Han Yi asked him to write, and seeing that his handwriting was not neat, joked to him: "The fifth son's painting is like this, but suddenly he was granted the post of Changshi Kaiguo. From now on, he should work harder!"
