The only ethnic Mongol township in Yunnan. Although the people known as "Yunnan Mongol", or Khatso, trace their ancestry to the Mongols of Khublai Khan, who conquered Yunnan in the 13th century, they actually speak the region's indigenous Yi language, rather than Mongol.
The Khatso people, commonly known as the Yunnan Mongols (云南蒙古族), is a Mongolic ethnic group, mainly distributed in Tonghai County in the Yunnan province of southwestern China. The Khatso people are descendants of the army personnel of the Yuan dynasty.
