【双语】你好！中国 | 守卫古代中国和平的城墙—长城
中国的长城是中国古代修建的巨大的堡垒，是有史以来规模最大的建筑工程之一。长城是由中国各个王国的不同边界防御工事和城堡发展而来的。
The Great Wall of China, a massive fortress built in ancient China, is one of the largest construction projects in history. It was developed from various border defense structures and fortresses of different kingdoms in China.
长城实际上是由许多城墙组成的，其中许多城墙彼此平行，建于中国北部和蒙古南部，历时约两千年。
In reality, the Great Wall is composed of many walls, with several walls running parallel to each other, built in northern China and southern Mongolia over a span of approximately two thousand years.
尽管长城的很长一段现在已经成为废墟或完全消失，但它仍然是地球上最引人注目的建筑之一。长城于1987年被联合国教科文组织列为世界遗产。
Although a significant portion of the Great Wall has now become ruins or completely disappeared, it remains one of the most remarkable architectural wonders on Earth. It was inscribed as a UNESCO World Heritage site in 1987.
