Difan 帝範

Difan 帝範 "Models for an Emperor" is a political treatise written by Emperor Taizong 唐太宗 (r. 626-649) of the Tang dynasty 唐 (618-907). Taizong intended to provide a handbook on governance to his sons to make ruling somewhat more manageable for them. The Difan is very short and includes 12 chapters. During the Song period 宋 (960-1279), a large part of it was lost, but a few centuries later, the missing parts were rediscovered during the Yuan period 元 (1279-1368), the missing parts were rediscovered.

The content of the Difan is geared to the Confucian interpretation of government. A ruler had to be benevolent and make use of able advisors. Nevertheless, the Difan also shows the practical spirit of legalism when speaking of punishment and the peasantry as a base of the economic and financial base of the empire.

There were two commentaries on the Difan, one written by Jia Xing 賈行 and one by Wei Gongsu 韋公肅 (fl. 826), which are both lost. The only extant commentary dates from the Yuan period, but the author is unknown. All modern editions are based on a version that has survived in Japan. The Difan is included in the series Siku quanshu 四庫全書, Zhibuzuzhai congshu 知不足齋叢書 and Yueyatang congshu 粵雅堂叢書.
