China is one of the four ancient civilizations and the only ancient country with an unbroken civilization. It is one of the oldest civilizations in the world. Ever since the first spark of Chinese civilization was born by the ancestors in the Yellow River basin, this spark has grown stronger and stronger, and after thousands of years of history, the wicker path has finally become a great fire that has illuminated the whole East. The development of Chinese civilization has not been smooth, it has also experienced failures, suffered calamities and gone to the abyss of destruction, however, Chinese civilization has survived with its strong vitality and absorbed the cultures of all races to form a more vibrant Chinese civilization. The long-standing and enduring Chinese civilization continues to this day, and the ancestors have left behind many precious cultural heritages for future generations, which are the most important treasures of Chinese civilization, and many of them have become the world's most recognized human treasures.

Chinese civilization is rich in cultural heritage, but if asked about the most representative cultural heritage of Chinese civilization, I am afraid that most people would answer "The Great Wall". When Chinese people talk about the Great Wall, they always proudly call it "The Great Wall of China", which has been the symbol of the Chinese nation since its birth, and its development history is also the history of the Chinese nation full of blood and tears.In ancient times, the central role of the Great Wall was to serve as a fortress against foreign enemies, hence its militarized designation such as the trench. The Chinese civilization was not weak in ancient times, and the ancestors revered great power and valued force. During the Xia, Shang and Zhou dynasties, the Chinese people often used military force to open up their territories and to defend themselves against foreign invasion and to deter covetous people. For example, the "Shang Shu - Shun Dian" contains the performance of Shun hunting; "Shi Jing - Zhou Song - Shi Mai" praises King Wu of Zhou hunting, "Huairou hundred gods, and the river Qiaoyue, Yun Wang Wei after. Ming Zhao in the Zhou, style order in the reign". Through these records, we can learn that the Chinese civilization was not afraid of war, but the Han people were an agricultural civilization and needed a fixed gathering place, while the nomads were not only powerful in fighting, but also not settled, even if the Central Plains regime defeated the nomads, it was still difficult to avoid their intrusion. In order to protect the border from invasion, the Chinese regime built the Great Wall at the border as a rift valley against the cavalry.

The history of the Great Wall can be traced back to the Western Zhou Dynasty, for example, the famous "Beacon and Fire", with the Great Wall as the background. During the Spring and Autumn Period and the Warring States Period, countries began to build their own Great Wall for hegemony, but most of the Great Wall built at this time was relatively short and rudimentary. It was not until the time of Qin Shi Huang that Qin annexed the six states and unified them under one roof. In order to maintain unity, Qin Shi Huang took a series of measures, and the construction of the Great Wall is one of the keys. After Meng Tian rejected the Xiongnu in the north and recovered the Henan region, Qin Shi Huang then ordered hundreds of thousands of conscripts to build the Great Wall of the Qin Dynasty, which "starts from Lintao (present-day Shanni County in Gansu) in the west and ends in Liaodong (present-day Liaoning Province) in the east, winding for more than 10,000 miles. From the point of view of people's livelihood, the construction of the Great Wall was a squeeze on the people's power, but from the perspective of the historical environment at that time, the construction of the Qin Great Wall was beneficial to the security of the country, and even the "Over the Qin", which was quite critical of Qin Shi Huang, praised the Qin Great Wall: "But the Xiongnu more than 700 miles, the Hu people did not dare to go south to graze their horses, and the soldiers did not dare to bend their bows and complain. "

Today, the Great Wall has become a symbol of the Chinese nation, a reflection of the hardships of the Chinese people along the way, and a symbol of the unity of the Chinese nation. During the war period, the Great Wall was ravaged by war, and in many areas the Great Wall has fallen into disrepair. It was not until 1952 that the government officially repaired the Great Wall and listed it as one of the first national key protection units, and in 1987 it was listed as a world cultural heritage site.It is the greatest military defense project in the world's ancient history, and its military defense ideology reflects the wisdom and tenacity of the Chinese people; it is also a symbol of the great unity of the Chinese nation, promoting the integration of various ethnic groups, ensuring the smooth flow of the Silk Road, and playing an important role in the world's understanding of China and China's protection of the world.
