《宋书·志·卷十六》
卫璀等人义上奏说： 我们听说唐尧、虞舜两代，救济世人弘扬功德的君主，没有不是对上回报天意，对下协同民心，登介丘山，上梁父山，没有推辞的，因为这是不可谦让的。
瓘等又奏： 臣闻唐、虞二代，济世弘功之君，莫不仰答天心，俯协民志，登介丘，履梁父，未有辞焉者，盖不可让也。
Wei Cuo and others memorialized: We have heard that the monarchs of the Tang Yao and Yu Shun dynasties who redeemed the world and promoted merit, without exception, reported to heaven and coordinated with the people's hearts, ascended to Mount Jieshan, and ascended to Mount Liangfu. , there is no excuse, because it is not to be humble.
