  Two accounts given by contemporaries Li Yangbing (a family relative) and Fan Chuanzheng state that Li's family was originally from what is now southwestern Jingning County, Gansu. Li's ancestry is traditionally traced back to Li Gao, the noble founder of the state of Western Liang. This provides some support for Li's own claim to be related to the Li dynastic royal family of the Tang dynasty: the Tang emperors also claimed descent from the Li rulers of West Liang. This family was known as the Longxi Li lineage (隴西李氏). Evidence suggests that during the Sui dynasty, Li's own ancestors, at that time for some reason classified socially as commoners, were forced into a form of exile from their original home (in what is now Gansu) to some location or locations further west. During their exile in the far west, the Li family lived in the ancient Silk Road city of Suiye (Suyab, now an archeological site in present-day Kyrgyzstan), and perhaps also in Tiaozhi (simplified Chinese: 条枝; traditional Chinese: 條枝; pinyin: Tiáozhī), a state near modern Ghazni, Afghanistan. These areas were on the ancient Silk Road, and the Li family were likely merchants. Their business was quite prosperous.
