Sogwo Arig (Sog Mongols; Sog: Mongol-in Tibetan language) claim to be descendants of Mongolian Yuan Dynasty rulers of Hunan province. French traveller Vicomte d'Ollone met with them in 1906 and the Sogwo Arig lord signed a letter with the title of "King of Hunan." Vicomte d'Ollone wrote: "When the Mongols were expelled from China, the dynasty of the kings of Ho-Nan [Hunan] - kings without a kingdom - retired to their steppes; and when in their turn the Manchus seized the empire  they utilized the Mongols for the purpose of holding the Tibetans in check, for which reason a horde was sent to establish itself in this region." The Sogwo Arig Mongol lords held their royal title until 1950s. They are nomads who live in Mongolian style yurt.
