[2] Following a palace coup in 705, which resulted in the restoration of the Tang dynasty and allowed Wu's son Zhongzong to reclaim the throne, Li Yong was promoted to the minor rank of District Magistrate of Nanhe (南和縣令).
Li Yong was first promoted to the major office of Left Imperial Censor (左臺殿中侍御史), before becoming the Ministry of Revenue's vice-director (戶部員外郎).
Being part of Cui Ruiyong's faction, Li Yong was likewise exiled and demoted to Assistant to the District Magistrate of Shecheng (舍城丞).
Throughout his political career, Li also served as the governor of several northeastern Tang states, including Kuozhou (括州), Zizhou (淄州), Huazhou (滑州), Jijun (汲郡) and Beihai (北海).
[6] Li's biography of Chinese Buddhist monk Daoxuan, believed to be the oldest such account, was written in 742 and inscribed on a stele in the Lingyan Monastery on Mount Taishan.
[11] Li's calligraphy was initially modelled on Wang Xizhi's,[12] before he developed "his own personal and innovative style of running script".
