《陈书·列传·卷二十七》
自从淳朴源头已经遥远，浇薄之风已扇，物的感人无穷，人的追逐欲望无节度，所以要设训诫垂风范，启导人的心灵，譬如那染蓝色，类似那雕琢玉，然后人伦可以和睦，尊卑会有序，忠孝之理明确，君臣之道久远不变。
自淳源既远，浇波已扇，物之感人无穷，人之逐欲无节，是以设训垂范，启导心灵，譬彼染蓝，类诸琢玉，然后人伦以睦，卑高有序，忠孝之理既明，君臣之道攸固。
Since the origin of simplicity and honesty has been remote, and the style of impetuousness and superficiality has prevailed. The worldly influences are innumerable, and the human desires are insatiable. Therefore, we should establish teachings and set the moral models, inspire the human mind, such as dyeing with indigo, similar to carving jade, so that the human relations can be harmonious, the high and low ranks will have their order, the principles between the sovereign and the minister, the loyalty and filial piety will be clear.
