Tengchong and Longling in Baoshan city, and Ruili and Longchuan in the Dehong Dai and Jingpo autonomous prefecture are home to many ethnic groups in the mountains of Yunnan province. With the exception of Longling, they sit on China's border.
Because of their remoteness and a lack of flat farmland, all the areas are a major challenge for Yunnan's poverty eradication campaign.
Over the years, local governments have helped many of the residents shake off poverty by developing tourism, agriculture and the jade industry.
Palian village in Tengchong was once only known for being rundown, however, it has become popular with visitors due to the development of tourist attractions.
Residents of Tengchong's Jietou township have cultivated hundreds of hectares of African marigolds.
