Paper focuses on statue and belief for "Vairocana Avalokitesvara", its presence has a close relationship to configuration of three mahàsattvas and images around its, no matter how three mahàsattvas themselves-from three saints of Hua-yen(Vairocana, Samantabhadra, Manjushri), or seeing from corresponding relationship of configuration of deities in temple hall in Song or Ming period, which all reflect equivalence and exchange between Vairocana and Avalokitesvara, "Vairocana Avalokitesvara" is a special statue and belief on the effect of atmosphere for preaches and thoughts and configuration for hall in Song and Ming periods, althought "Vairocana Avalokitesvara" has no direct classical traces, and is different from general folk belief, it gradually integrates and absorbs classical theories of every school in the process of evolution of faith, it is affected by Hua-yan Thoughts and Avalokitesvara Practices in Esoteric Buddhism in early times and later added into the thoughts for Shurangama Sutra and Lotus Sutra and elements of folk belief, so there is profound foundation of Buddhism preaches at the back of statue and belief for "Vairocana Avalokitesvara".
