The Geat Wall    The Great Wall, symlolizing China’s ancient civilization, is one of the world’s most renowned projects. A well-know popular saying goes: “He who hadn’t been to the Great Wall is not a true man ”/ “You are not a pluck hero till you climb the Great Wall.” Therefore, everyone tried to make it.   Construction of the Wall first began during the period of the Warring States (476 BC-21 BC). Formerly, walls were built at strategic points bu different kingdoms to protect their northern territoried. In 221 BC after the first Emperor of the Qin Dynastyunified China, he decided to have the walls linked up and extended.    Historical records show that about one million people, one-fifth of China’s population at the time. were involved in the project, which took more than ten years.When it was finished we call it “Wan Li Chang Cheng”which means “Ten Thousand Li(5,000 kilometres) Long Wall” .Now, nature has taken over most of the Great Wall.    The Great Wall, which we are going to visit, was rebuit during the Ming Dynasty in the 16th century. It extends from Shanhai(mountain and sea). Pass ,a seaport along the coast of Bohai Bay, to Jiayu Pass in Gansu Province. Its total length is more than 6,700 kilometres.
