Aerial photo taken on June 4, 2020 shows the eco-agricultural park of the Baicaopo farmers' cooperative in Zhaozhuangzi Village of Tangshan City, north China's Hebei Province. Barren hills in the Zhaozhuangzi Village have been transformed into an eco-agricultural park after the Baicaopo farmers' cooperative was founded here in 2009. The cooperative organized farmers to plant grain crops, pine trees and various fruit trees in different parts on the hills, as well as raising chickens under trees, which helped local farmers increase incomes.
