Have you ever been to the Great Wall in China? Have you heard of the saying"He who doesn't reach the Great Wall is not a true man”? Like the Pyramids(金字塔) of Egypt, it is one of the seve n wonders in the world and is known to people all over the world . Every Chinese will tell you that it was built in the Qin Dynasty, the ruler ( 统治者 )of which was Qin Shihuang. In fact , it took a long period of time to build it in China's history. We can hardly tell how many years it took. We don't know how many stones were used to build the wall. We don't know how many people died in building the Great Wall. We only can say that it was built with the blood and sweat (汗水) of the Chinese working people 。 The Great Wall has stood there for thousands of years. It is the pride of the Chinese nation. If you have a chance to go to China some day, be sure to go there and have a look at the great wonder.
