李广
The Kyrgyz khagans of the Yenisei Kyrgyz Khaganate claimed descent from the Chinese general Li Ling, grandson of the famous Han dynasty general Li Guang. Li Ling was captured by the Xiongnu and defected in the first century BCE and since the Tang imperial Li family also claimed descent from Li Guang, the Kirghiz khagan was therefore recognized as a member of the Tang imperial family. Emperor Zhongzong of Tang had said to them that "Your nation and Ours are of the same ancestral clan (Zong). You are not like other foreigners."
