《宋书·志·卷二十七》
帝尧把功劳归于舜，将要把天下让给疆，于是洗浴斋戒，在黄河、雒邑修建坛场，选择吉曰率领爱等人登上首山，沿着黄河边行进。
归功于舜，将以天下禅之。乃洁斋修坛场于河、洛，择良日，率舜等升首山，遵河渚。
Emperor Yao attributed the credit to Shun, and he was about to yield the throne to Xiang, so he bathed and fasted, built a platform at Luo, designated a lucky day, and led Yi and others to ascend the Shoushan Mountain, marching ahead along the Yellow River.
