The Great Wall
We can see walls everywhere in the world. But the Great Wall of China is the longest wall ever built by man. The Chinese call it “the Ten-Thousand-Li Great Wall”. In fact it is more than 6,000 kilometres long. It is 7 metres high"and"4.5 metres from one side to the other. In most places, five horses or ten men can walk side by side on it.
When you visit the Great Wall, you can’t help wondering how Chinese people built such a wall thousands of years ago without any modern machines. It was really very difficult to build. They had to do all the work by hand. What great people they were! It took millions of men hundreds of years to build it.
The Great Wall has a history of over two"thousand"years. Kings began to build the first parts of it about two"thousand"seven hundred years ago. Then Qin Shi Huang had all the walls joined up. He thought it could keep the enemy out of the country.
Today, the Great Wall has become a famous place of interest. Many people, both in China"and"abroad, come to visit it. How wonderful the Great Wall is!
