This revised bilingual edition of the Dao De Jing features Professor Gu Zhengkun's updated translation, which reorganizes the original 81 chapters into 98 sections across six thematic parts for clearer comprehension. The second volume includes The Great One Begot Water — a Daoist text discovered in a tomb of the ancient State of Chu, considered by many scholars to be the oldest existing writing on Chinese cosmology. To assist international readers, the texts of both The Book of Dao and De and The Great One Begot Water are matched with Chinese phonetic symbols.
