We can see walls everywhere in the world. But the Great Wall of China is the biggest of all. The Chinese call it "The Ten-Thousand-Li Great Wall". It is in fact more than 6000 kilometers long. It is 6～7 meters high and 4～5 meters wide. In most places, five horses or ten men can walk side by side along the top.

    When you visit the Great Wall, you can't help wondering how the Chinese people were able to build such a great wall thousands of years ago. Without any modern machines, it was really very difficult to build it. They had to do all the work by hand. It took millions of men hundreds of years to build it.

    The Great Wall has a history of over two thousand years. The men began to build the first parts of it around two thousand seven hundred years ago. Then QinShihuang had all the walls joined up. He thought that it could keep the enemy out of the country.

    Today the Great Wall has become a place of interest. Not only Chinese people but also people from all over the world come to visit it.
