《后汉书·列传·张王种陈列传》
是说成王令德，不过循用旧的典章而已。考大汉最初兴隆，及中兴之世，文帝和明帝，道德教化更盛。
寻大汉初隆，及中兴之世，文、明二帝，德化尤盛。
This means that King Cheng is virtuous, but he just follows the old rules. If we look at the beginning of the Han Dynasty, as well as the period of restoration, Emperor Wen and Emperor Ming promoted morality and education even more.
