Emperor Xuanzong of Tang
In 742, an imperial proclamation from Emperor Xuanzong of Tang canonized the "Zhuangzi" as one of the Chinese classics and awarded it the honorific title "True Scripture of Southern Florescence" ("Nánhuá zhēnjīng" ). However, most orthodox Chinese scholars did not consider the "Zhuangzi" to be a true "classic" ("jing" ) due to its non-Confucian nature.
