Dong Zhongshu
The Luxuriant Dew of the Spring and Autumn Annals () is one of the works attributed to Dong Zhongshu that has survived to the present, though its compilation might have continued past his lifetime into the 4th century. It is 82 chapters long and about 72,000 words, although three of the chapters within the present text have been lost, and there is considerable textual confusion in other chapters. In its current form, the book deals with topics such as the five elements and their relation to politics. One of the chapters in this book presents the concept of the "source" (元), which became important to later Neo-Confucianism.
