Chinese genealogies are far more than simple family trees—they are elaborate books, often produced as printed volumes. As the most popular books in premodern China, genealogies can still be found in almost every village in southern China today. They gained popularity in Chinese villages between 1450 and 1950, evolving continuously in format, style, and content. This talk will introduce the structure, contents, and format of Chinese genealogies, as well as their changes over time.   Xin Yu is a Visiting Assistant Professor in the History Department at University of Wisconsin-Milwaukee.
