Mingsha Mountain is located seven kilometers south of Dunhuang City. In ancient times, it was called Shensha Mountain and Shajiao Mountain. The whole mountain system is made of sand, which is about 4 kilometers long from east to west, 2 kilometers wide from north to south and tens of meters high. The peak is steep and like a blade. There is a wet sand layer under the sand dune. The wind blows the sand particles and the sound can cause the sand layer to sing, hence the name. According to historical records, when the weather is clear, even if the wind stops and the sand is quiet, it will sound like playing music, so the "clear sound of sand ridge" is a scene in Dunhuang. If people fall from the top of the mountain, the sand will fall with the human body, and the sound will be heard all the time, which has a special interest. It is said that when you climb the sand mountain at night, you can also see sparks generated by the sliding friction of sand grains. Mingsha Mountain, Shapotou in Zhongwei County, Ningxia, Xiangshawan in Dalate Banner, Inner Mongolia, and Balikun Sand Mountain in Balikun Kazak Autonomous County, Xinjiang, are also regarded as the "four famous Mingsha Mountains" in China. This is a kind of wonder in natural phenomena, which is known as "desert wonder" throughout the ages and is known as "one of the best scenery beyond the Great Wall".

Crescent Moon Spring is located at the foot of Mingsha Mountain. It was called Shajing in ancient times and Yaoquan in common name. It has been one of the "Eight Scenes of Dunhuang" since the Han Dynasty, and it was named "Yue Quan Xiaoche". Crescent spring is nearly 1 meters long from north to south, and about 25 meters wide from east to west. The spring is deep in the east and shallow in the west, and the deepest part is about 5 meters. It bends like a crescent moon, hence its name, and it is called "the first spring in the desert". A clear spring bends, ripples linger, and it is as blue as jade. The spring is in quicksand, the drought is not exhausted, and the wind blows the sand, which is a spectacle. Scholars in past dynasties praised this unique mountain spring landform and desert wonder. The pavilions and pavilions have been built by the crescent spring, and the scenery is quite beautiful, plus the undulating sand mountains, clear spring water and brilliant sunset.
