Introduction to the sand-crossing highway: The sand-crossing highway is named after it crosses the Kubuqi Desert. It is the sixth largest desert in my country and the closest desert to Beijing. The construction of the highway ended the history of Kubuqi Desert obstructing traffic. It also served as a window for publicizing scenic spots, national customs and ecological construction. Along the Chuansha Highway, you can visit Daotu Qixing Lake, Chuansha Fishing Village and other scenic spots.
