The Great Wall of China, a wonder of the world, is called "The Ten Thousand Li Great Wall" in China. 它是世界上最长的城墙。 It's over 4000 miles long, 6-7 meters high and 4-5 meters wide. The Great Wall has a history of more than 2000 years. All the walls were joined up in Qin Dynasty. In ancient days it was difficult to build such a wall. Our forefathers (祖先) carried, lifted and laid big bricks and stones with simple tools. Each brick and stone fits well, even though they didn't have our modern machines! All the work was done by hand. Thousands of people died while building the Great Wall.
Since then, it has been repaired and rebuilt many times. Now the Great Wall has been on a new look.它已经成为了一个非常著名的地方。 It's visited by a large number of people from all over the world. Many of them have got to know the famous Chinese saying "He who does not reach the Great Wall is not a true man."
