This book relates the source of the Ping-pu group's land rights and their changes in the period between the 17th and 19th centuries. The author takes the case of an important Ping-pu clan-- the Anli people of the north-eastern Taichung basin--, and then uses the residual contracts and documents of the Anli people and various files from public and private institutional repositories to analyze how the Anli people used the forms of contracts to develop their land resources together with Han tenants, and also undertook initial distribution of rural property rights.
