The main chamber is square in plan with a central altar, and the front chamber is rectangular in plan. Both are connected by a long corridor. In the Maitreya sutra illustration in this cave, there is an inscription in ancient Tibetan and an image of a wedding ceremony of a Tibetan man with a Chinese woman, from which it can be determined that it was constructed in the period when Guazhou was occupied by the Tibetans and Shazhou was not yet, namely from the 11th year of Dali era (776) to the second year of Jianzhong (781). Part of the ceiling of the main chamber has collapsed, and the front chamber was renovated in the Five Dynasties. The original paintings are well preserved. On the east wall is a Mandala of Eight Bodhisattvas, on the south wall is an Amitayus sutra illustration, and on the north wall is a Maitreya sutra illustration. On both sides of the illustration are single images of Avalokitesvara, Mahasthamaprapdta and Kistigabha bodhisattvas. On the two sides of the entrance in the west wall are illustrations of Manjusri and Samantabhadra. In the front chamber, the south side and north side of the east wall respectively depict Vidudabha and Vaisravana, who protect the paradise of Buddhism.
