《魏书·列传·卷四十一》
开阔神都以延续帝王之业，在中土建造帝王之都，当年周公行之在前，如今陛下行之于后，所以这是很合适的事情。
廓神都以延王业，度土中以制帝京，周公启之于前，陛下行之于后，固其宜也。
It is reasonable to develop the capital to continue the emperor's cause and establish the emperor's capital in central China. In the past, Duke Zhou did it first, and now your majesty does it again.
