Yot Ou

Yot Ou lies in the mountain country of the upper Ou River, at the southern edge of the Cheli world. Known in Chinese records as Wude, it was paired with neighbouring Mengwu in one of the twelve banna under the Cheli ruler in the Ming period. These districts connected the Tai communities of the south with Jinghong and the uplands of Yunnan. In 1725 the Qing established a hereditary local office at Mengwu under Ning'er, changing the administrative ties of the upper Ou country.
