"The mountain coexists with the spring, each gives life to the other." This is how people describe Ming Sha Mountain and the Crescent Moon Spring in Dunhuang of Gansu. Since ancient times, it has been referred to as “The foremost scenic spot of the northern frontier”. At one time though, it almost disappeared due to inadequate protection. The local government implemented a number of measures, water level of the Crescent Moon Spring has gradually moved back up. A triumph of combining nature and conservation work.
