A "zupu" () is a Chinese kin register or genealogy book, which contains stories of the kin's origins, male lineage and illustrious members. The register is usually updated regularly by the eldest person in the extended family, who hands on this responsibility to the next generation. The "updating" of one's "zupu" () is a very important task in Chinese tradition, and can be traced back thousands of years. After several generations, the local clan lineage will often publish a compendium of these zupus. The overwhelming majority of zupus remain in private hands, though a large number may be found in the Peking University, Shanghai Library, Cornell University and Tōyō Bunko.
