This video course will give students an example of a miracle in the history of world architecture--the Great Wall, and lead you to visit Shanhaiguan, an important pass on the Great Wall, and the old dragon head of the eastern starting point of the Ming Great Wall. The Great Wall is a symbol of Chinese civilization and bears witness to China's long history. Shanhaiguan is connected to the Great Wall, with the city as the pass, is a world cultural heritage, known as the "first pass in the world." The old dragon head enters the sea and the stone city is like a dragon head into the sea, making waves and dancing, boarding the old dragon head, facing the turbulent, cloud-bound sea, enjoying the magnificent scenery and generating endless reverie. I hope students can enjoy the beautiful scenery and feel the infinite charm of Chinese architecture.
