Zhuang Zhou, honorifically often known as Zhuangzi, was an influential Chinese philosopher who lived around the 4th century BCE during the Warring States period, including the Hundred Schools of Thought period, which is a period of great development in Chinese philosophy. He is credited with writing—in part or in whole—a work known by his name, the Zhuangzi, which is one of two foundational texts of Taoism, alongside the Tao Te Ching.
