Li Zhengji
The Tang emperors liberally granted the royal surname to favoured generals, officials, and their clans, such as Xu Shiji, Du Fuwei, and Guo Zihe (郭子和). Many non-Han people under Tang's rule were also granted the Li surname, including the Eastern Tujue khan Ashina Simo (Li Simo), Mohe leaders Li Duozuo and Li Jinxing (李謹行), Khitan leaders Li Guangbi and Li Jinzhong, and Goguryo general Li Zhengji. Some Tibetans, Uyghurs, Persians, and Jews were also granted the Li surname. The number of people surnamed Li skyrocketed during the Tang dynasty.
