Go to Guyuan. In the distance of the valleys and mountains, hills and hills lined with the trend, low in smoke. The Great Wall of Qin turned eastward. The Qin people rammed the Great Wall, and the Song people dug side ditches along this line. Jin Cuibao's Ancient and Modern Notes - Capital: "The Qin Dynasty built the Great Wall, and the soil was purple, so did the Han Fortress, so it was called Zisaiyan." A paragraph by Yang Jiang, It was said with tears: "I once researched the origin of Zisai, and only knew that the soil under the Great Wall was purple. One said that there were purple flowers under the Great Wall. The soil color in China was different, including loess, red soil, black land, etc. Under the Great Wall, the soil was purple. Why? Did the people who built the Great Wall survive?...... The people's flesh and blood mixed with the soil, which was purple. The purple flowers in this soil were really the flowers of blood and tears." In front of the dilapidated fortress, wall cutting and corner pier, I just stared at the gray yellow soil of the Warring States Period, without saying a word. My fingers poked out and separated the fluffy autumn grass swaying gently in the wind, as if I saw the red blood seeping out and slowly seeping away. My heart beat fast, and my eyes pierced through the scattered debris to cast their shadows on the unknown city builders. When I left, the dusk crept silently around me and swallowed up the weak sky light. The shadow of the Great Wall faded into the night. Move day and month. The vast border walls and ditches have long been out of use for defense, but they refuse to retreat from people's view and remain stubbornly in time. Polished by the years, it has become a magnificent landscape on the earth's surface, and has even become a spiritual symbol. The background set by the ancients was so extraordinary that special behaviors and scenes were set off against it, and the view became stronger. This section of the Great Wall, built during the reign of Emperor Zhaoxiang of Qin Dynasty, passed from Jingning County, Gansu Province, to Xiji County, Ningxia. More than 80 years ago, the autumn was deep. The Central Red Army, which had marched into the Liupan Mountains, crossed the Great Wall pass several times. This is a picture of how to excite the soul! So dignified, so solemn, and so freehand. Everything is heroic, bright, mighty, majestic and epic. The Great Wall and the Long March have such a large geographical span and such a long time influence. Both the leaping posture in the mountains and the footprints in the war are engraved in the history, which will never disappear. On the Liupan Mountain, the polar view is blue. All the green in the world rushed towards the peak ridge, just like the billows hitting the floating reef. Chinese fir, maple, birch, linden, chamomile, aspen, juniper, Liaodong oak, Huashan pine, swaying branches and leaves, rush to the sky. The mountain wind plays clear notes in the forest. My eyes are far away and my thoughts are far away. The main peak of Longshan Mountain is the last mountain that the Central Red Army climbed before reaching the Shaanxi Gansu Soviet Area. Deep in the rocks, the hot blooded soldiers, with their bayonets carrying the flying clouds, were marching forward with their hearts. The scenery on the mountain was different in those days. Chen Changfeng, the guard of Chairman Mao, said: "Although Liupan Mountain is not the largest snow mountain we have passed before, it has 60 miles up and down. There are still some trees to support it when we first go up the mountain. When we get to the top of the mountain, there are no trees. Only some grass is dying, so it is more difficult to walk." The sky is full of floating clouds, the mountain is full of tight wind, the front is wet and cool rain, and the front is full of dust and
