The study about the relationship between Buddhist monks, nuns and Sheyi (社邑, community) in Dunhuang from late Tang Dynasty to the early North-Song Dynasty(about 9th-10th Centuries) was making progress, because someone found the Dunhuang manuscripts about one hundred years ago. From the 1930s of the twentieth Century to the recent years, some scholars have been studying the hundred years old Dunhuang manuscripts, explaining their contents, participants and activities of Dunhuang Sheyi manuscripts. Their research provided us a good start to understand the social life of Buddhist monks and nuns in Dunhuang. Obviously there is a close relationship between Sheyi and local Buddhist monastic life in Dunhuang, and some monks and nuns in the monastery hold the most important leadership roles in Sheyi. The members of Sheyi would follow their orders, whether economic or religious orders. The monks and nuns might even be one of the chief leaders of these medieval communities. In Dunhuang, there were members of Sheyi who were taking some charitable and relief activities under the leadership of the Buddhist monks and nuns. In addition to their mutual work in various religious charitable activities, they also constructed grottoes and conducted some ceremonies. At the same time, we also found a large number of records that showed how the Dunhuang Sheyi members overcame difficulties in funerals or major accidents in their social life and how they had asked help from Sheyi. In other words, the members of Dunhuang Sheyi could receive assistance from Sheyi. Some Buddhist monks and nuns were managers of Sheyi, and they would help the members through Sheyi by using the collective investment way. Associated with these Sheyi activities, some Buddhist monks and nuns might get a little help from Dunhuang Sheyi. These helped us to understand how Buddhism entered into Chinese society and their great impact on traditional Chinese folkorganizations. They would be reflected as something initiated by the private sector, groups and event, and they could also be seen as a particular type of religious charity.
