Great Wall of China - The Chinese language DragonWhen seen from above the Nice Wall of China seems to be like a dragon zigzagging over mountain tops. The Chinese language name it "Wan Li Chang Cheng" which implies "Wall of 10,000 Li". (10,000 li= 5,000 km)
Really, the Nice Wall is 7,200 km lengthy. Peak clever, it's 4.5m to 9m. Depth clever, it's 4.5m to 8m. All the construction was constructed by hand utilizing stone, bricks, soil, sand, straw, wooden, clay or no matter was obtainable relying on the terrain.
Three most important Chinese language dynasties -- the Qin (B.C 221-207), Han (B.C 206- A.D 220) and Ming (A.D 1368-1644) -- constructed the Nice Wall of China. All had one goal -- to maintain out the "barbaric" Huns within the north who regularly invaded Chinese language border areas. In all, tens of hundreds of thousands of individuals labored on the Nice Wall. Many died.
Qin Shi Huang, the First Emperor of China, is credited with kicking off this large venture 2,200 years in the past. By connecting outdated sections with newly constructed ones, the Qin Dynasty erected 4,800km of wall in 10 years - a couple of km a day!
After the Qin, the Han Dynasty prolonged the Nice Wall by means of the Gobi Desert. Watchtowers have been added to the partitions. Smoke spirals produced by burning wooden and straw combined with wolf dung functioned as an alarm system. One smoke column meant a power of 100 males was attacking; two columns signaled that greater than 500 males have been approaching, and so forth.
The Nice Wall of China we all know at present was constructed by the Ming Dynasty 600 years in the past. By then the traditional wall was in ruins. The Ming rulers rebuilt most of it over a interval of 200 years. That the wall continues to be in good situation at present is because of an invention of that period, the including of rice flour to make tremendous sturdy bricks and mortar!
