Unique barrier slows encroachment of desert sand

An afforestation site has become a fascinating attraction recently for tourists in Wuwei's Minqin county in Gansu province.

A sand-trapping barrier composed of clay, gravel and bags of soil combines with a glaze of snow to create some unique scenery in the desert. The barrier is helping to prevent the Badain Jaran and Tengger deserts from merging into each other, protecting the ancient Silk Road.
