Li Youdao (李游道) was an official of Wu Zetian's Zhou dynasty, briefly serving as chancellor.
[1] It is known that his clan was a prominent one, from what was one point Zhao Commandery (趙郡, roughly modern Shijiazhuang, Hebei), that traced its ancestry all the way back to the great Warring States period Zhao general Li Mu.
[2] As of 692, Li Youdao was serving as the chief judge of the supreme court (司刑卿, Sixing Qing) and the acting prefect of Shan Prefecture (陝州, roughly modern Sanmenxia, Henan), when Wu Zetian made him the minister of public works (冬官尚書, Dongguan Shangshu).
She also gave him the designation Tong Fengge Luantai Pingzhangshi (同鳳閣鸞臺平章事), making him a chancellor de facto.
Eight months later, however, he, along with other chancellors Wang Xuan, Yuan Zhihong, Cui Shenji, Li Yuansu, and other officials Kong Siyuan (孔思元), and Ren Linghui (任令輝), were falsely accused of crimes by Wu Zetian's secret police official Wang Hongyi.
