《宋史·列传·卷一百一十九》
皇上亲自书写 忠正德文 四字赐给赵鼎，又把亲笔写的《尚书》一卷赐给他，说 ：《尚书》所载为君臣相互戒饬之言，之所以赐给你，打算与你共保此道。 赵鼎上疏称谢。
上亲书 忠正德文 四字赐鼎，又以御书《尚书》一帙赐之，曰： 《书》所载君臣相戒饬之言，所以赐卿，欲共由斯道。 鼎上疏谢。
The Emperor personally wrote the four characters “loyal and righteous virtues” and gave them to Zhao Ding. He also bestowed on him a scroll of the Book of Documents in his own handwriting, saying: The content of the Book of Documents is words of mutual exhortation between rulers and ministers. The reason I have given it to you is that I intend to observe this Way together with you. Zhao Ding submitted a memorial expressing his gratitude.
