     We can see many walls 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 6,000 kilometers long. It is 4-5 meters
wide. In most places, five horses or ten men can walk side by side.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 kings began to build the first parts
of it around two thousand seven hundred years ago. Then Qin Shihuang had all the walls joined up. He
thought that 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.
