本书内容来自国家社科基金项目“明清戏曲宗元研究”（项目编号：11BZWO61），基于明清戏曲与元代戏曲的关系而立论。明清戏曲创作和理论领域普遍存在“宗元”的观念、现象与思想，与诗文领域的宗唐、宗宋、宗汉等具有近似的理论价值和创作指导意义。从“宗元”视角切入明清戏曲研究，将促成戏曲史观念的多元化，解决许多不易解决或那些理解上尚有待深化、细化的戏曲史、文学史命题。

The content of this book is from the National Social Science Foundation project "Zongyuan Research on Ming and Qing Opera" (project number: 11BZWO61), based on the relationship between Ming and Qing opera and Yuan opera. The concept, phenomenon and thought of "Zongyuan" are common in the field of Ming and Qing opera creation and theory, and have similar theoretical value and creative guiding significance to Zongtang, Zongsong and Zonghan in the field of poetry. Entering the study of Ming and Qing opera from the perspective of "Zongyuan" will promote the diversification of the concept of opera history and solve many propositions in the history of opera and literature that are not easy to solve or whose understanding needs to be deepened and refined.（AI翻译）
