This book introduces the formation process of ritual culture, in which “reverence” and “sincerity”serve as the spiritual core. It also explores the historical context and moral tradition of Chinese rites from the perspectives of self-cultivation, family ethics, and nation-building, revealing the historical and cultural roots that form the basis of the Chinese way of thinking and behaving. Moreover, this book explains the values and contributions of Chinese diplomacy with “harmony” as an essential element of China’s ritual culture.
