Making small pagoda is a religious custom in Tibet. People firstly make a clay impression of a pagoda and bake it. The result is a pottery pagoda. The pagoda is of cone shape, and different sizes. Inside the pagoda, there are a small piece of paper written with spell, and a small amount of highland barley. The small pagoda, usually placed around a big pagoda or a statue, is used as the sacrifice to the Buddha. In Aba district, Tibetan people pray for a bumper harvest year by putting small pagodas at the side of a road, a village or burying them in the farming land in the hope that they will kill harmful insects.
