The Book of Master Lieh
The Lieh Tzü is a Taoist text attributed to Lieh Yukou, a circa 5th century BCE Hundred Schools of Thought philosopher, but Chinese and Western scholars believe it was compiled around the 4th century CE. During the reign of Emperor Xuanzong of Tang, the Lieh Tzü was designated a Taoist classic, completing the trilogy with the more famous Tao Te Ching and Zhuangzi. The Lieh Tzü is generally considered to be the most practical of the major Taoist works, compared to the philosophical writings of Lao Tzü and the poetic narrative of Zhuangzi.
