The Naxi from Lijiang
The Naxi, who for centuries had their own independent kingdom at Lijiang (just to the east of Kachin state) speak a language closely related to both Burmese and Yi. They also have an amazing writing system of their own. As you can see, the words for 'eye', 'food' and 'goral' or 'goat' are very similar to Burmese. Their kingdom came gradually under Chinese influence. But it was only really integrated into China in the 1950s.
