It is said that astronauts flying into space have reported that only two human projects can be identified from the distant moon, one of which is the Great Wall in Wan Li, China. The majestic Great Wall of Wan Li is one of the wonders of the world created by the ancient people of China, and it is also a monument in the history of human civilization. According to historical records, since the Warring States period, more than 20 vassal states and feudal dynasties have built the Great Wall. The first is Chu, which began to build the Great Wall to defend the northern nomadic people or enemy countries. Later, countries such as Qi, Yan, Wei, Zhao and Qin began to build their own Great Wall for the same purpose. After Qin unified the six countries, Qin Shihuang sent a famous soldier Meng Tian to explore the Xiongnu in the north, connecting the Great Walls of various countries, stretching for thousands of miles from Yao in the west to Liaodong in the east, hence the name Wan Li Great Wall and the name "Wan Li Great Wall". But what we see today is mainly the Ming Great Wall.

There are only relics left in Qin Changcheng. Qin Shihuang built the Great Wall with 300,000 people, which created a miracle in the history of human architecture. The construction of the Great Wall objectively played a positive role in preventing the Huns from invading the south and protecting the economic and cultural development of the Central Plains. Dr. Sun Yat-sen once commented: "Although the first emperor had no choice, the Great Wall made great contributions to later generations. In fact, Dayu managed water and so on."

The Han Dynasty continued to build the Great Wall. From Wendi to Xuan Di, a 10,000-kilometer-long Great Wall was built, starting from Dawaner Shicheng in the west and reaching the north bank of Heilongjiang in the east. Half of the ancient Silk Road was along this Great Wall, which is the longest in history. In the Ming Dynasty, in order to prevent the invasion of Tatars and Waci people, the construction of the Great Wall never stopped. From Hongwu to Wanli, during this period, it was built on a large scale for 20 times, starting from Jiayuguan in Gansu in the west and ending in Hushan in Liaoning in the east, and a 6350-kilometer-long side wall was built. (But it is reported that in 1990, the pedometer of a China man who walked the whole Great Wall showed 6700 kilometers. The Great Wall has great tourism value and historical and cultural significance. Now, after careful development and restoration, Shanhaiguan, Juyongguan, Badaling, Simatai, Mutianyu and Jiayuguan have become famous tourist attractions at home and abroad. Looking into the distance, with the ancient bosom, the ancient battlefield seems to be just around the corner. Today, the Great Wall, together with the Golden Pagoda in Egypt, the Colosseum in Rome and the Leaning Tower of Pisa in Italy, is considered as the seven wonders of the world. It is a monument of China's ancient culture and the crystallization of wisdom, symbolizing the blood and national spirit of the Chinese nation.

The Great Wall of Wan Li began in the Spring and Autumn Period and the Warring States Period, accompanied by the feudal society of China for more than two thousand years. As we all know, the ancient civilization in China has a long history, and the feudal society is the richest and most brilliant chapter. All the major political, economic, cultural and historical events in the feudal society have left their marks on the Great Wall. The Great Wall is a symbol of the Jin-Goma Railway, the struggle for deer to strengthen fields, the change of dynasties and the struggle for national peace. As a historical monument, the Great Wall has made the hydrology of China. The Great Wall of Wan Li contains the splendid culture and art of the Chinese nation for more than 2,000 years, and its connotation is very rich. In addition to the architectural layout, modeling, sculpture and painting of the city wall, Guancheng, Zhencheng and beacon tower, there are also poems and songs, folk literature and opera rap. Throughout the ages, I don't know how many emperors, generals, foot soldiers, poets and poets have left immortal chapters for the Great Wall. Frontier poems have become an important school in classical literature. For example, Li Bai's "Harmony with the wind, which has traveled thousands of miles, beats on the battlements of Yumenguan", Wu Changling's "The bright moon in Qin Dynasty was closed in Han Dynasty, and people were not returned on the Long March", the five-dimensional "Advise you to have a glass of wine, and people have no reason to go out to bask in the sun", and Cen Can's "Like spring breeze, a dead tree and a pear flower come at night" have all been recited for thousands of years. The lyrics of Meng Jiangnu's sending cold clothes are still widely sung. The Great Wall is a place for patriotic education and a tourist attraction. It symbolizes the indomitable spirit and perseverance of the Chinese nation to overcome difficulties with its majestic posture and strong physique. This spirit inspires us to move forward forever. Sightseeing is not only a tour, but also a comprehensive function of keeping fit, increasing knowledge, keeping in touch with friendship and developing economic and trade activities.

Former British Prime Minister Heath said during his visit to the Great Wall: "China's past and future are equally fascinating. ..... When I arrived at the Great Wall, I felt more spectacular than the Great Wall I had seen in photos, embroidery and painting before. " This just shows that tourists want to visit the Great Wall in person.
