The main part of the Qianfoyan Rock Carvings was built between the 1st and 10th years of the Yongle reign of the Ming Dynasty (1403—1412). As a small grotto of the early Ming, it provides a well-defined chronological reference within the Dazu Rock Carvings. The 14 niches mainly focus on Pure Land belief, and thesubjects include the Twelve Light Buddha, the Three Saints of the West, the Illustration of the Amitayurdhyana Sutra, Thousand Buddhas, Ksitigarbha, Avalokitesvara, and the Seven Buddhas of the Past. The Qianfoyan Rock Carvings are of great academic value for refining the chronological sequence of the Dazu Rock Carvings and for the study of the spread of Pure Land belief, folk Buddhist art, and the transformation of grotto art in eastern Sichuan during the Ming Dynasty.
