Tubo
Or "stod" (meaning the upper part, that is, the west).
Tubo (A.D. 6 18 -842, Tibetan:? Willie: bon chen po, which means "A Fan") is a political power established by ancient Tibetans on the Qinghai-Tibet Plateau, which lasted more than 200 years from Zanri to Langdama. The Tubo dynasty was the first regime with a clear historical record in Tibetan history, and Songtsan Gambu was regarded as the actual founder of the country. Under the unification of the Tubo dynasty, the various parts of the Qinghai-Tibet Plateau condensed into powerful forces and gradually stepped out of the closed inland plateau, which made the ancient Tibetan society glow with vitality for the first time.
The Ming Bamboo Slips of Wang Tong's Genealogy and Wang Tong Ji of Tibet compiled by Sonan Bamboo Slips recorded that the national emblem of Tubo was translated into Liu.
