《汉书·志·郊祀志下》

孝武皇帝祠雍，曰： 今上帝朕亲郊，而后土无祠，则礼不答也。 于是元鼎四年十一月甲子始立后土祠于汾阴。
Emperor Xiaowu worshipped Yongdi, saying: Now that I personally go to the suburbs to pay homage to the God of Heaven, but Houtu has not been sacrificed to, which is not in accordance with the etiquette. So in November of the fourth year of Yuanding, at Fenyin, he established the Houtu shrine.
