Tianjian Shi passed away unexpectedly on December 25, 2010, leaving this book’s completed manuscript, which had been accepted by Cambridge University Press. I undertook the final editing with the professional assistance of Mary Child and the technical help of Tianjian’s former student, Jie Lu. As peer reviewers for the Press, Dorothy J. Solinger and Doh Chull Shin provided valuable suggestions for revisions. I thank John Aldrich for finding the funds to support Mary Child’s work. Some minor queries that came up in the course of editing could not be resolved. I regret any errors or confusion that I may have introduced into the text.
