The individual sections weren't connected until the Qin dynasty (221-206 B.C.). Qin Shihuangdi, First Emperor of Qin began conscripting peasants, enemies, and anyone else who wasn't tied to the land to go to work on the wall. He garrisoned armies at the Wall to stand guard over the workers as well as to defend the northern boundaries. The tradition lasted for centuries. Each dynasty added to the height, breadth, length, and elaborated the design mostly through forced labor.
中国的长城共有近一万公里，东起河北秦皇岛的山海关，西到嘉峪关，这是明代修筑长城的二个最大关口，北京境内的长城有600余公里，比较著名的有八达岭长城、金山岭长城、司马台长城、慕田峪长城、居庸关长城和箭扣长城等。北京的长城，大部分是公元1540年前后，明代时修建的，距今已有450年的历史。长城是中华民族精神的缩影，也是中华民族文明的象征。万里长城是世界建筑奇迹之一。它东、西、南、北纵横交错绵延起伏于中国辽阔的土地上。东西相距长达5000多公里，因此被称之为万里长城，是月球上“ 唯一能看得见的人工工程”，也是中国第一名胜和中国旅游点的代表，被联合国科教文组织列入《世界文化遗产名录》。 万里长城是公元前7世纪开始修建的。当时，中国北方诸侯割据，他们为了防御邻近诸侯的侵袭，在各自的领土上先后筑起了一段段防卫墙。与此同时，燕、赵、秦三个诸侯国的北方，又与少数民族中以游牧为主的匈奴族为邻，为了防御匈奴奴隶主的骚扰，三国各自都在他们的弱方修筑了长城。到了公元前3世纪秦始皇统一了中国，把一段段的长城连结起来，成了现在万里长城的基础。后来经过历代增建，及到明朝，就修成了现在的这个样子。它东起渤海湾的山海关，经河北、北京、山西、陕西、内蒙古、宁夏到甘肃的嘉峪关，穿过崇山峻岭，山涧峡谷，绵延起伏，长约12000多华里，因而名为万里长城。 在古代交通运输工具极其落后的情况下，修建如此巨大的工程，实在是一件了不起的事。特别是它不是一般的土墙，而是整齐的条石和结实的青砖砌筑的。有人计算，如果把明长城所用的砖、石和土方，筑成一道2米厚、4米高的围墙，可以绕地球一周。不用说烧制这些砖石，就是把它们通过崎岖的山间小路送达修建工地，已经是一项十分宠大的工程。游览长城的人莫不为先民的伟大气魄和坚毅精神所感动。 Hong Kong International Airport
