Heilai Ditch is located at Dalat Banner, close to the Kubuqi Desert. Agriculture and animal husbandry are the main local industries, and desert erosion is the biggest "enemy" of local development.
Engelberg is located in the middle section of Kubuqi, one of China's eight major deserts. It was a livable place in history, but due to unduly land reclamation, grazing and wars, it turned to desert.
