My sincere gratitude goes to Julia Watson. Without her insight and support, it would have taken much longer for this book to take shape. I am indebted to Patrick Riley and Yanfang Tang for their valuable suggestions. I also thank Tani Barlow, Xiaomei Chen, Jinhua Dai, Perry Link, and Patricia Sieber for their encouragement. Especially deserving of my acknowledgment is Hao Yan, who showed endless patience in helping me find rare sources needed for annotation. Special thanks also extend to the Research Council of Colgate University, Case Library at Colgate University, Kroch Library at Cornell University, Beijing University Library, Nanjing Library, and Shanghai Library.
I genuinely appreciate the warm love from my families and friends.
