On the way back along the path, I found the northeast corner of West Yun Guan near Dunhuang Park. After calculating the time, I found myself a little nervous, so I never walked into the park again and took a taxi directly to Mingsha Mountain and Crescent Spring. In the off-season, Moon Spring in Mingsha Mountain is only half-price 60 yuan, valid for 3 days. My friend has already arrived at Mingsha Mountain before me. I changed my ticket, changed my orange sand shoe cover, walked along the veranda, and met my friends at the camel team distribution center. We decided to try to ride a camel to Mingsha Mountain. Three people happily chose their favorite camel and led the team all the way. Although they are herbivores, camels are surprisingly strong. Not only do you not tremble when you get up, but you walk as steady as Mount Tai. I thought it would nervously hold the handrail with both hands all the way, but in fact it was busy taking selfies and chatting. Along the way, I found a woman wearing red western-style clothes on the opposite hillside, taking a photo with a camel. The wind rolled up the yellow sand, and the red skirt curled up in the air. I can't help regretting that I didn't bring that red imperial costume, otherwise what a visual feast it would be! The camel team didn't go to the highest peak, but just walked along the gentle sand dunes and reached the finish line. Next is our own time.

Mingsha Mountain is very big, stretching for 40 kilometers and very small. If you stand on the highest peak, it is said that you can see the Mogao Grottoes at the eastern end and the Danghekou at the western end. Crescent Spring, in the embrace of Mingsha Mountain, stands at the drop-off place of camel team, and you can see the antique tower next to Crescent Spring. Although surrounded by mountains, Crescent Spring has never dried up for thousands of years, and I don't know how many business travelers and passers-by on the Silk Road have been saved. However, with the development of human science and technology in the last century, the sudden increase of water consumption led to the continuous decline of the groundwater level in Dunhuang, and the Crescent Spring once dried up. In recent years, the water supply project called "Don't let Dunhuang be the next Loulan" has achieved initial results, and the crescent spring has been refilled, restoring the crescent shape lying on the sand. However, this reborn crescent spring can't help but make me wonder: did the crescent spring save mankind or did mankind save the crescent spring? Both ends of Crescent Moon Spring have signs of the best places to watch, and most of the photos of Crescent Moon Spring taken in the market are taken from these two angles. Last April, I took countless photos in these two venues. Yellow sand is reflected in the spring water. When the wind didn't come, the waves didn't move, and time seemed to be sealed in this curved spring. On the side near Gu Lou, reeds are overgrown and the white dew is frost. Brush past clumps of reeds, I imagine that when the autumn wind is tight, reeds ride the wind, reflect into the crescent spring, fly, fly over the reflection of the spring, fly over the long sand dunes, fly over the endless Gobi Desert, and fly over the Millennium.

Thanks to the nourishment of the crescent spring, Salix psammophila and Populus euphratica grow by the spring for a hundred years. They stubbornly leaned out in the baptism of wind and sand and years, leaving a tortuous shape, guarding this magical spring water year after year. Unlike last time, there were not many tourists. We took pictures under the biggest old Populus euphratica tree as a souvenir, and later found that I had lost an earphone.
