The Great Wall,with a history of more than 2,000years,was regarded as a wonder of China.From abird's-eye view,it is just like a dragon winding itselffrom west to east,stretching for approximately6,700 kilometers.Since the Spring and AutumnPeriod and the Warring States Period,the walls had been put up to defend the borders by thekingdoms.After the founding of Qin Dynasty，Qin Shi Huang had all the walls joined together tomake "The Great Wall".While most of the walls were ruined in wars,the majority of the GreatWall we see today was mainly built during Ming Dynasty.The Great Wall,originally built to resistthe invasion from the North,now has become a well-known place of interest,attracting touristsfrom all over the world.As a saying goes,"He who has never been to the Great Wall is not a trueman"，which is evidence of its grandeur.
