《明史·列传·卷一百七十》
晋武帝欲按旧制而不能行，魏孝文帝也未完全实行，宋孝宗锐意复古，也未能推行于下，这些都不足以成为圣王之至孝。
晋武帝欲行而不能，魏孝文行之而不尽，宋孝宗锐志复古，易月之外，犹执通丧，然不能推之于下，未足为圣王达孝也。
Emperor Wu of Jin wanted to follow the old system but could not do so, and Emperor Xiaowen of Wei did not fully implement it either. Although Emperor Xiaozong of Song was determined to restore the ancient ways, he could not extend them to the people below, so these were not enough to be called the utmost filial piety of the sage emperors.
