(10) The Flame Emperor Shennong Shi (surnamed Jiang; styled the Flame Emperor. His mother was Nüdeng Shi, who gave birth to him upon being moved by a divine dragon. He had a human body and an ox's head. He grew up by the Jiang River and took it as his surname). He ruled by the virtue of Fire. His capital was at Chen, and he moved it to Quwo. He reigned for 140 years and was buried in Changsha. The Classic of Changes says: 'Shennong Shi carved wood to make plowshares and bent wood to make plow handles.' He first taught the realm to sow and plant the five grains. He also tasted the hundred flavors to establish the Materia Medica and cure ailments with medicines; he multiplied the eight trigrams into the sixty-four; he created markets for the barter of commodities; he instituted sacrificial robes and made the five-stringed qin zither to mirror the Five Phases. From him downward came Emperor Cheng, Emperor Linkui, Emperor Ming, Emperor Zhi, Emperor Lai, Emperor Ai, and Emperor Yuwang: altogether eight generations, lasting 540 years.
