The zupu in China, jokbo in Korea and gia phả in Vietnam is the printed lineage genealogy, and it is a substantial document — often many volumes, revised every generation or two by a compiling committee funded by subscription. It records every male descendant by generation, together with branch histories, biographies of distinguished members, the lineage rules, the location of graves, the property of the estate, and prefaces solicited from eminent outsiders. A distinctive device is the generational name: all males of one generation share a character in their given name, drawn from a poem fixed in advance, so a name announces its bearer's position in the lineage to anyone who knows the sequence. Women historically appeared, if at all, as a surname — daughter of the Kim family — without a personal name. That has begun to change: a number of Korean and Chinese lineages have revised their genealogies since the 1990s to enter daughters by name and to include married-out descendants, and the change is argued over inside lineages rather than imposed on them.
