你知道有个叫八台子的地方，长城与教堂相依偎吗？你知道在老牛湾，长城与中华民族的母亲河——黄河相交融吗？你知道西水峪水长城上，春天的美景宛如桃花源吗？烽两位作者将历史与现实、人文与风光、正史与传说、资料与实践结合在一起，用风趣的语言、精美的图片、独特的立意，向我们展示了一个不一样的长城，一个更加生动的、有血有肉的长城。 With a total length of 21196.18 kilometers (including 6,259.6 kilometers of artificial walls), the Great Wall represents the wisdom of the Chinese nation developed since ancient times. It has been a mute witness of Chinese history stretching back more than two millennia. It is the largest ancient defense pro- ject constructed over the longest span of time. Since there was a historical record of the two Chinese characters Chang Cheng (Great Wall) in the Spring and Autumn Period (770-476 BCE), the work of building and maintaining it has been a continuous process for well over two thousand years encompass- ing vast areas of north and central China. The Great Wall bears the precious historical memory and national spirit of the Chinese nation. With the passage of time, many sections along its 5,000- km length have been destroyed, although the names remain. Sections of the Great Wall extant today, known almost to all, include Badaling, Shanhaiguan and Jiayuguan.
