Midu, a county in Dali Bai autonomous prefecture in Yunan province, impresses visitors with its beautiful scenery and a diverse culture and folklore contributed by different ethnic groups of people living there, including Peng Feng, a professor of Peking University.
Three years ago, Peng and his team came to Midu to assist with poverty elimination and urban rejuvenation by means of culture and arts. They set up a working station of public education and founded a children's choir — inspired by a long-lasting love and tradition of group singing there.
