The Jino are one of the less numerous of the recognized minorities in China and the last one included as "national minority" because they were only recognized in 1979. A former name used for the Jino, Youle, means "following the maternal uncle," an indication of a matrilineal past.
The Jino have a population of 20,900 people according to the census of the year 2000. Most of the Jino concentrate in the Jinoshan Mountain, in a series of mild hills with wet climate near Mengyang Township in Jinghong Municipality, Xishuangbanna Dai Autonomous Prefecture of Yunnan Province. They live in an area of about 70x50 km. They live in subtropical rainforest, home of elephants, wild oxen and monkeys.
Among their cultural practices is tooth painting, in which soot made from pear trees is used.
