Introduction to the main room: The diameter of the arched hall is 6.85 meters. In the center of the hall is a statue of Sakyamuni Buddha, carved from white granite and 3.48 meters high. The Buddha statue sits cross-legged on the octagonal lotus stone platform, with a calm and tranquil expression, his wise eyes slightly open, wisdom condensed between his kind brows, his nose and mouth that seem to be opening his mouth to preach, and his drooping ears, all showing the nobility of his inner world. . There are 11 reliefs of Avalokitesvara and Buddha's 10 disciples carved on the surrounding stone walls; there are Avalokitesvara statues placed in some niches on the upper part of the stone wall and under the dome, and the dome is decorated with reliefs.
