Zhuangzi (book)
The Zhuangzi (historically romanized Chuang Tzŭ) is an ancient Chinese text that is one of the two foundational texts of Taoism, alongside the Tao Te Ching. It was written during the late Warring States period (476–221 BC) and is named for its traditional author, Zhuang Zhou, who is customarily known as "Zhuangzi" ("Master Zhuang").
