Huainanzi
The Huainanzi (Chinese: 淮南子) is an ancient Chinese text that consists of a collection of essays that resulted from a series of scholarly debates held at the court of Liu An, King of Huainan, sometime before 139 BC. The Huainanzi blends Daoist, Confucianist, and Legalist concepts, including theories such as Yin-Yang and the Five Phases.
The Huainanzi's essays are all connected to one primary goal: attempting to define the necessary conditions for perfect socio-political order. It concludes that perfect societal order derives mainly from a perfect ruler, and the essays are compiled in such a way as to serve as a handbook for an enlightened sovereign and his court.
The book
The date of composition for the Huainanzi is more certain than for most early Chinese texts. Both the Book of Han and Records of the Grand Historian record that when Liu An paid a state visit to his nephew the Emperor Wu of Han in 139 BC, he presented a copy of his "recently completed" book in twenty-one chapters.
