As a rare ancient military defense project in the history of world architecture, the Great Wall is not only a symbol of the Chinese nation and an important symbol of Chinese culture, but also a precious historical and cultural heritage of the world. In the eyes of foreigners, the Great Wall symbolizes China's 5,000-year-old Chinese civilization, and foreigners' understanding of China first comes from the Great Wall.

The saying “He who has not been to the Great Wall is not a true man” applies not only to Chinese people, but also to foreigners. Therefore, whether it is foreign dignitaries or ordinary people, the first thing they want to see when they come to China is definitely the Great Wall.
