The Great Wall of China,also known in China as the Great Wall of 10,000,is an ancient Chinese fortification built from the end of the 14th century until the beginning of the 17th century,during the Ming Dynasty,in order to protect China from raids by the Mongols and Turkic tribes.It was preceded by several walls built since the 3rd century BC against the raids of nomadic tribes coming from areas now in modern day Mongolia and Manchuria.The Wall stretches over a formidable 6,350 km (3,946 miles),from Shanhai Pass on the Bohai Gulf in the east,at the limit between China proper and Manchuria,to Lop Nur in the southeastern portion of Xinjiang Uygur Autonomous Region.

　　The first major wall was built during the reign of the First Emperor,the main emperor of the short-lived Qin dynasty.This wall was not constructed as a single endeavor,but rather was created by the joining of several regional walls built by the Warring States.It was located much further north than the current Great Wall,and very little remains of it.A defensive wall on the northern border was built and maintained by several dynasties at different times in Chinese history.The Great Wall that can still be seen today was built during the Ming Dynasty,on a much larger scale and with longer lasting materials (solid stone used for the sides and the top of the Wall) than any wall that had been built before.The primary purpose of the wall was not to keep out people,who could scale the wall,but to insure that semi-nomadic people on the outside of the wall could not cross with their horses or return easily with stolen property.

　　中国的长城,在中国也被称为10000年的长城,是中国古代建造防御工事结束从14世纪到17世纪初,明朝期间,为了保护中国从蒙古和突厥部落的袭击。它之前是几个墙建自公元前3世纪游牧部落的袭击来自现在在现代蒙古和满洲地区。长城延伸一个强大的6350公里(3946英里),从山海关在渤海湾东部,在限制中国的满洲,罗布泊新疆维吾尔自治区东南部的部分。

　　第一个主要墙建成第一个皇帝的统治期间,主要的短暂的秦朝的皇帝。这堵墙是不作为一个努力,而是由几个地区的加入墙由战国。这是位于比当前更北的长城,,仍然很少。北部边境的防御墙是建立和维护由几个王朝在中国历史上不同时期。仍然可以看到今天的长城建于明朝,规模更大、更持久的材料(固体石用于墙的两侧和顶部)比任何以前建成的墙。墙上的主要目的并不是将人拒之门外,谁能规模墙上,而是确保外的墙上半游牧的人无法跨越的马很容易与赃物或返回。
