Shanhaiguan山海关Shanhaiguan became known as the First Pass Under Heaven since ancient times.山海关自古就有天下第一关的美称，It is situated in the east of Qinhuangdao City,Hebei Province, forming a pass of strategic importance at the eastern end of the Great Wall.它坐落在河北省秦皇岛的东部,在长城的东端形成一个具有战略重要性的关卡。It was set up by General Xu Da in 1381 (the 14th year of the Ming Hongwu reign) when a castle was erected here.由许达建立于1381年(明洪武十四年)当时只有一个城堡建于这里。Five kilometers to the east of Shanhaiguan, the starting point of the Great Wall dips into the sea like a dragon's head.五公里长的东山海关，长城的起点像冲入大海的龙的头部。

Piling 10 meters high and dipping 21 meters into the sea,the rocks chum the surging waves.桩高10米和浸渍在海里21米,惊涛骇浪拍打着岩石。Hence the name Old Dragon Head. It is a complex of a stone fortification,the Jinglu platform,the South sea pass,and the Chenghailou Tower and the Ninghai Castle.老龙头因此得名，它由入海石城、靖卤台、南海口关和澄海楼和宁海城堡组成。
