The cliff sculptures on Yuchan Mountain in Luxian County of Sichuan were mainly carved during the Ming Dynasty. Among them, the niche of Nine Loongs Bathing the Prince located around the Thousand-handed Avalokitesvara is themed on Jātaka tales, which represents a relatively rare subject matter containing rich historical information in grottoes of the Sichuan-Chongqing region. This niche of bathing the prince is a type developed during the later period in the eastward transmission of similar subject matter. The hand gestures of the prince is also a distinctive feature representing both a return of early iconography and an integration of three scenes, including birth, loong bathing and seven-step declaration. The construction of the niche of loong bathing the prince on Yuchan Mountain might be resulted from the belief in Shakyamuni and the tradition of praying for blessings.
