Introduction to the Bodhi Hall: A plaque with the name "Yinshan Ancient Temple" hangs high, and a prayer flag pole towers in front of the hall. The two large flagpoles are used to dry the Buddha on the fifteenth day of the first lunar month. The purpose of drying the Buddha is to dry the Thangka of Buddha Sakyamuni, the largest collection in the temple. One is to make the Buddha's light shine on the people of Qingcheng, and the other is to prevent the thangka from being eaten by insects.
