The Dao De Jing (Tao-Te-Ching, c. 4th century BCE), traditionally attributed to Laozi, and the Nan Hua Jing (Zhuang Zi) are considered the key texts of the tradition.[119] The first organized form of Taoism, the Tianshi (Celestial Masters') school arose in the 2nd century CE. Xuanxue ("deep learning", also "Neo-Taoism") was a major philosophical movement influenced by Confucian scholarship, which focused on the interpretation of the Yijing, Daodejing, and Zhuangzi and which flourished during the third to sixth centuries CE.[120] The most important philosophers of this movement were He Yan, Wang Bi, the Seven Sages of the Bamboo Grove, Ge Hong and Guo Xiang.[121] Thinkers like He Yan and Wang Bi focused on the deep nature of Tao, which they saw as being best exemplified by the term "Wu" (nothingness, non-being, negativity).[122]
