You may wonder why there is still a Great Wall in the scenic spots of Shuidonggou. In fact, the Great Wall has been destroyed almost, and it is only a small section of the defense system in the Great Wall. Compared with the Great Wall in Beijing, there are not so many stones. After reading it, I feel more like the Great Wall in Jiayuguan, but no matter how, the feeling of seeing the Great Wall can only be imagined, because many monuments have not been preserved. But we also have to lament that the greatness of the ancients in such a difficult situation, actually built the Great Wall to defend against foreign enemy aggression.
