英语翻译
The conflict caused many farmers to migrate southward,leaving large areas of farmland in the north to waste.Dong continues,＂In order to halt this agricultural retreat,troops were sent in by the government of the Central Plains areas to protect farmers and their land,but they would arrive only to find that the marauders had already retreated.The nomads would simply renew their attack as soon as the troops had withdrawn.″Construction of the Great Wall,therefore,was with the aim of restoring order to the farming economy,and the function of troops stationed on it was to maintain peace on the border.
The Great Wall to some extent promoted development of border trade.As the nomadic economy produced only meat and hides,nomads would attack Central Plains farming communities and pillage the cloth and iron implements they produced.As Dong Yaohui explains,＂Construction of the Great Wall prevented looting and established trade.″Great Wall passes such as the Niangzi and Zijing were outposts for collecting tariffs.
＂Few battles occurred along the Great Wall for thousands of years,and those that did were of short duration.The Great Wall was built to avoid wars,and its solidity was with the aim of maintaining peace.There are forks on certain sections,and it is not continuous in mountainous regions as building on steep slopes was pointless.The Great Wall,therefore,should not be defined simply as a military project,″Dong Yaohui concludes.
＂A main principle followed in building the Great Wall was to ‘take advantage of natural barriers and take measures appropriate to local conditions,’″is Zhou Youma’s reply to Franz Kafka’s questions.

冲突引起了许多农民往南移动,离开北方的农地大区域浪费.Dong,”为了要使农业的休息寓所停止,军队被送在被中央的平原政府区域保护农民和他们的土地,但是他们不料竟会会到达找 marauders 已经撤退.游牧民族会只是更新他们的攻击像军队一样的很快有了长城的 withdrawn.〃建筑,因此,是由于回复对耕作经济的次序目标,和功能被安置在它上的军队要维持在边缘方面的和平.
对一些范围的长城促进了边缘贸易的发展.当游牧的经济生产了唯一的肉和兽皮的时候,游牧民族会攻击中央的平原耕作社区而且掠夺布料,而且铁实现他们生产.当 Dong Yaohui 的时候,长城的”建筑避免掠夺而且建立了 trade.〃长城途径 ,像是 Niangzi ,而且 Zijing 是收集关税的前哨.
很少的战争沿着长城发生数千年的”,和做的那些是短期间.长城被建造避免战争,而且它的固体性是由于维持和平的目标.有在某区段上的叉子,而且它当做在险峻的倾斜上建筑在多山的区域中不是连续的是不尖的.长城,因此,只是不应该被定义如一个军事的计画,〃 Dong Yaohui 推论.
主要的原则在建筑长城方面跟随的”一是到‘利用天然的障碍而且采取对地方性的情况是适当的措施,'〃是对弗朗茨 Kafka's 的问题 Zhou Youma's 的答复.
