When a grain of sand fell into the world, Dunhuang began to exist. On the way to Dunhuang Mogao Grottoes, the car passes through the boundless desert like a sharp arrow. The straight asphalt highway is like a surging river, gurgling into the distance. The camel walking slowly has become the text and symbol of the desert. Perhaps, only this vast and vigorous land can bear the massiness of Mogao Grottoes. I have been to Longmen Grottoes and Yungang Grottoes, but none of them shocked me. Mogao Grottoes is not limited to the centralized narration of a dynasty. It is a colorful painting with rich white space. Where the pen of history stops, the feelings of continuation will flicker. In addition to the tall Buddha statues in Mogao Grottoes, the most striking thing is the brightly colored murals. When you approach and appreciate them carefully, it seems that you can still feel the breath and aftertemperature of history. The appearance of these murals is completely different from that of postmodern works. They often have a visual edge, but are gentle and quiet. When appreciating the painting, people can give up the tedious thoughts and let the heart flow in the painting like a stream. There was once a river in front of Mogao Grottoes, but it has dried up, leaving only a poplar telling about the past and future. The little green struggling out is particularly dazzling in the desert, which is a kind of arrogance of life. The white poplars that guarded the soil and water knew that they were facing the swallowing of the desert, but they never retreated. The nine floors of Mogao Grottoes are like a eagle with lofty aspirations and spread its wings. We mortals who live like mayflies will never understand that we want to take off happily in the long river of history. Most of the Scriptures in the Sutra pavilion have been lost, and many valuable cultural relics have been scattered all over the world. The scars of history unfold impressively, and the pain remains. Not far away is crescent spring. The crescent moon spring is deeply covered in the towering Mingsha mountain. The sand dunes of Mingsha mountain are like majestic peaks. Those warriors who successfully climb the dangerous peaks may not still have the courage to continue to write the peak here. The crescent Moon Spring falls into the vast desert like a drop of tears. Even if no one can understand its bitterness and sadness, it always calls in people's ears - "maybe you don't understand this kind of love, unless you go there to have a look". With my guitar on my back, I learned the song "crescent spring" and prepared to sing a chorus with my friends against the background of crescent spring. We repeated it nearly 30 times before we finally finished singing accurately and smoothly. I know that crescent moon spring does not lack tenacity, because no matter how bad the situation is, it will not dry up the water of life, so take my hymn here. Mingyue Pavilion is a sword, an invincible and invincible sword. It shows the world the spiritual height of the towering crescent spring, forbearance, loneliness, but tenacity. Therefore, above the Dongting, there is the Yueyang Tower, which "worries about the world first, and then enjoys the happiness of the world"; In Yuzhang County, there is Tengwang pavilion with "sunset and solitary ducks flying together, and autumn water is the same as the sky". They are located in a prosperous place, sung by scholars and scholars and respected by the world. Deep in the desert, Mingyue pavilion was silent and watched alone in the lonely years. My friends and I rushed up Mingsha mountain. Standing on the top of the mountain, I suddenly had an illusion that if I wanted to fly high, I could grow a pair of wings on the Mingsha mountain immediately. Looking back at the long desert behind me, I tried to imagine what a vast spiritual territory would be in the distance beyond my vision. In this situation, we can't help singing on the guitar against the background of crescent spring again. At this moment, the wind and sand of Mingsha mountain is the symphony of our singing; At this moment, the agitation of life is the appearance of our youth. (outlook new era)
