Zhang Changzong
As of 698, Li Jiao was serving as "Mishu Shaojian" (秘書少監), the deputy head of the Palace Library, when he was given the designation "Tong Fengge Luantai Pingzhangshi" (同鳳閣鸞臺平章事), making him a chancellor "de facto". In 700, Wu Zetian, in order to give her lovers Zhang Yizhi and Zhang Changzong legitimacy in their entries into the palace, had Li Jiao head a project to create a work known as the "Essence of Pearls from the Three Religions" (三教珠英, "Sanjiao Zhuying") – a compilation of various poetry about Confucianism, Buddhism, and Taoism – and had Zhang Yizhi and Zhang Changzong involved in the project as well. Later that year, after Wu Zetian named Li Jiao's uncle Zhang Xi as a chancellor, Li Jiao, who was by this point serving also as "Luantai Shilang" (鸞臺侍郎), the deputy head of the examination bureau (鸞臺, "Luantai"), had his chancellor designation removed, because Wu Zetian did not want uncle and nephew to serve as chancellors at the same time. Li Jiao was instead made "Chengjun Jijiu" (成均祭酒), the principal of the imperial university.
