Seeing this huge project again is still exciting. It is impossible to imagine how many people's mental efforts were consumed by the 6,000-kilometer Great Wall under such conditions as in ancient times.
6000 km, what kind of distance is it? From the southernmost point of Shenzhen to Harbin, the whole journey is 3400 kilometers, equivalent to two such lengths. Moreover, it is all built between the lofty mountains!
Among them, the length of the artificial wall is 6,259.6 km; the length of the trench is 359.7 km; and the length of the natural hazard is 2,232.4 km.
The walls of the treacherous eastern part, made of strips of stone and green brick, are very strong. The Ming Great Wall stretches from Liaoning Hushan on the banks of the Yalu River in the east, connects the Great Wall of Qin, and then to Jiayuguan in the west, winding for more than 6,000 kilometers, with a magnificent momentum, which is a miracle in the world.
The large-scale construction of the Great Wall by the Ming Dynasty began in orthodoxy and ended in the last year of Jiajing, which lasted 130 years. During the more than 200 years of Ming rule, the construction of the Great Wall was hardly stopped.
The Beijing section of the Great Wall spans five counties and districts in the northern mountains of Beijing, namely Pinggu, Miyun, Huairou, Changping and Mentougou, with a total length of 629 kilometers (of which the main trunk line is 529 km long and the branch line is 90 km long). According to the investigation, the cumulative length of the preserved intact is 67 km, the basic complete 6 km, the medium 116 km, the bad 95 km, the worst 295 km. There are a total of 827 city platforms (including enemy platforms, wall platforms and battle platforms) on the Great Wall Line. The entire trend of the Great Wall of Beijing is relatively continuous and complete in a semi-circular shape.
"Thousands of ancient Hu soldiers bow down, and ten thousand heavy flesh and blood cast tranquility."
The Central Plains peoples, the invasion of foreign tribes, the least resistant is the iron horse. The Great Wall is the best way to deal with this killing move. It is not surprising that there is an idea to build the Great Wall, but it is the greatest miracle that it is truly implemented and successfully built, and has been preserved for more than 2,000 years to the present!
Looking at the inside and outside of the Great Wall, only Yu Mang; The river went up and down, and suddenly it was gushing.
Only this word can express one or two.
