Temple is a special organizing form in society with the complicated hierarchical relation in the inner part. In the 8th century, there appeared some hierarchical differences on assignment in Sangye temple after its foundation. This is just the beginning of inner hierarchy of Tibetan temples. Since the Houhong period, the hierarchical difference of monks grew more evident, even that the two classes of the governing and the governed arose. Temple therefore became the miniature of Tibetan feudal society of the serf system.
