The Great Wall of China is the largest earth work in the world.
Like a long snake it winds its way from Shanhaiguan Pass on the east coast to Jiayuguan Pass in the Gobi desert. The main part of the wall is about 2150miles long. It didn't become the "Great Wall" until the Qin Dynasty.
Qin Shihuang ordered his people to connect the separate walls. In order to prevent enemies out of China. Each dynasty added to the wall's height and lenght.
It didn't reach 6400 kilometers long until Min Dynasty. Now the Great Wall is a world-famous tourist attraction. It's the symbol of the wisdom of the ancient Chinese.
