《旧五代史·其它·外国列传二》
吐蕃，原居于汉朝西羌地区，有人说他们是南凉秃发利鹿孤的后裔，他的子孙以秃发为国号，语音讹变为吐蕃。
吐蕃，本汉西羌之地，或云南凉秃发利鹿孤之后，其子孙以秃发为国号，语讹为吐蕃。
The Tubo people originally lived in the Western Qiang region of the Han Dynasty. Some say they are the descendants of Tufa Lilugu of Southern Liang, whose descendants used Tufa as their national name, which was corrupted over time to Tubo.
