Emperor Jing of Han
The title "Daodejing", with its status as a classic, was only first applied from the reign of Emperor Jing of Han (157–141 BC) onward. Other titles of the work include the honorific "Sutra (or "Perfect Scripture") of the Way and Its Power" ("Daode Zhenjing") and the descriptive "5,000-Character Classic" ("Wuqian Wen").
