          Tourists get a sense of the history of the ancient irrigation system.[Photo/Xinhua]

          In order to make this vast desert into a comfortable and livable oasis, residents use the karez system, an invention that provides water through a technique derived generations ago.

          This system consists of well-like vertical shafts connected to underground channels that surface in the form of ditches and small ponds.
