《明史·列传·卷一百七十》
诏令礼官参考经史所载规定，使丧事不违礼仪，朝廷不耽误政事。定为不可更改的制度，传于子孙后代，岂不是件伟大的事情。 
诏礼官参考载籍，使丧不废礼，朝不废政，勒为彝典，传之子孙，岂不伟哉。 
You ordered the ritual officials to refer to the regulations recorded in the classics and histories and to ensure that the mourning rituals conformed with proper etiquette and that affairs of state were not neglected. It would be a great thing if you were to establish this as an unalterable institution to be passed down to your descendants.
