Highlights: Daqing Ditch is a long, beautiful and fertile ditch. As the "Green Pearl of Horqin Sandy Land," it was named "Chonghule" by Mongolians. There are verdant trees and blooming flowers in the ditch. The springs from the bottom of the ditch converge to form a twisted, clear creek. Various plants are grown on both sides of the ditch, including evergreen and deciduous trees, with bushes in between. It is a perfect choice in high season in China.
