《汉书·传·王莽传上》
把这件事交主管官吏讨论，他们都说： 古时候天子封赏王后的父亲纵横各一百里的土地，尊敬他而不把他作为臣子看待，藉此表示重视宗庙，这是至孝。
事下有司，皆曰： 古者天子封后父百里，尊而不臣，以重宗庙，孝之至也。
The matter was handed over to the relevant officials in charge for discussion. They all said: “In ancient times, the emperor used to reward the father of the queen with lands a hundred li in length and width. He was treated with respect and not regarded as a subject, to show great importance to the ancestral temples. This is the height of “filial piety.”
