The construction time of the cantilever Great Wall was built in the 19th year of Ming Jiajing (1540), and was built by Li Han, the supervisor of Suzhou, and has a history of more than 600 years. The main function of this cantilever is to hold the gorge of Montenegro and create an indestructible line of defense for the Jiayuguan Guancheng in the desert. Since its construction, it has accompanied Jiayuguan through the wind and rain for several years, large and small. The war has also experienced countless times. In ancient times, because of the inconvenience of transportation and transportation, most of the places where the Great Wall was built were used locally to save costs and time. The same is true of the cantilever Great Wall. The walls are not covered with blue brick and gray tiles, and the reeds unique to Jiayuguan are used. The grass and gravel are mixed and built. Because the reeds and gravel contain a lot of salt and alkali, when the salt and alkali decompose and solidify, the wall becomes a solid body. Although it has been attacked by a hundred years of sand, it is still rock solid. This shows the ingenuity of ancient craftsmen. When walking in this majestic cantilever wall, the four hundred steps of high and low undulations are all made up of stones and yellow sand. Every step is deep, and the heart always has a lot of sighs. The pattern on the step under the foot has long since disappeared, leaving behind the mark of the visitors. Looking from the bottom of the mountain from the bottom up, it seems that you can't see the end of the road, from walking easy to heavy walking. Looking around, the Gobi surrounds the entire wall, and there are sporadic weeds that make people feel extremely desolate. But it is in such a bleak environment that watching the Great Wall of the Wall has an inexplicable greatness, and this feeling is shocking.
