《贞观政要·卷三·君臣鉴戒》
我私下观察在朝身任要职的众大臣，有的是在西北地区担任过边防的重臣，有的是在朝廷参与朝政的要员。他们都建功立业，功勋卓著，都是当代优秀的人才。他们处在最关键的重要地位，责任非常重大。
窃观在朝群臣，当主枢机之寄者，或地邻秦、晋，或业与经纶，并立事立功，皆一时之选，处之衡轴，为任重矣。
I have observed the important ministers of the court, some are important ministers who have served as border guards in the northwest, and some are important officials who have participated in national affairs in the court. They have all made great achievements, and they are all outstanding talents of their time. They are in the most critical and important positions, and their responsibilities are very important.
