This cave was constructed in the Tang dynasty and its corridor was renovated in the Song dynasty. It has a truncated pyramidal ceiling and a west niche. The ceiling of the main chamber features a medallion pattern formed by four cloud motifs and the draperies extend to the four slopes which are covered with the thousand Buddha motifs with a seated Buddha in the center. The tent-like ceiling of the west niche contains a five figure group: one Buddha two bodhisattvas and two disciples. The U shaped altar has six small frames decorated with musicians. The center of the niche ceiling highlights a painted medallion. The west slope is decorated with draperies on the upper and two screen paintings below which illustrate Buddha's life stories including the bathing scene of the prince by nine dragons. The north slope shows the same design as the south one but the screen paintings illustrate the Three Assembly of Maitreya namely the Maitreya sutra illustration. The edge of the niche is decorated with ocean pomegranate and twisted vines. On the upper of the niche are curtain designs with an apsara on each side. There is an adobe platform on each side alongside the niche and there was originally a statue (now lost). Below the niche are images of Manjusri Samantabhadra and Mt. Wutai. Alongside the niche on the south side is an illustration of Samantabhadra and on the opposite side is that of Manjusri. The south wall depicts the Diamond sutra illustration on the west side and the Amitayus sutra illustration on the east side both having screen paintings below (vague). The north wall depicts the Panikarasuttau sutra illustration on the west side and that of the Medicine Buddha on the east side both having screen paintings below (vague).
