我们去了中国的万里长城，这是一座历史悠久的文化遗产，也是世界七大奇迹之一。我们在长城上漫步，欣赏着美丽的景色，感受着壮观的历史。长城的建造始于公元前7世纪，它曾经是中国古代的防御工事，也是中国文化的象征之一。

We went to the Great Wall of China, which is a historic cultural heritage and one of the seven wonders of the world. We walked along the Wall, enjoying the beautiful scenery and experiencing the magnificent history. The construction of the Great Wall began in the 7th century BC. It was once a defense work of ancient China and also a symbol of Chinese culture.
