The Shifugou Cliff Sculptures of Wuan comprise 18 extant niches, with inscriptions dated to the 2^nd year of the Xining era in the Northern Song Dynasty. The Baijiazhuang Cliff Sculptures feature 22 extant niches, including inscriptions from the 8^th year of the Jiayou era of the Northern Song Dynasty. The Cejingcun Cliff Sculptures contain 24 extant niches, including inscriptions from the 1^st and the 3^rd year of the Yuanfeng era of the Northern Song dynasty. These three sites show rich contents, including popular theme of the Northern Song Dynasty, such as the Three Sages of Huayan, the Sixteen Arhats, and the Water-Moon Avalokitesvara, which make them typical from the Northern Song period in southern Hebei. At the same time, the emergence of new iconography such as the combination of Water-Moon Avalokitesvara and animal imagery, and the depiction of Shelifu, reflects the secularization of Buddhism.
