The Great Wall of China: See the Hidden Story Behind this. The Great Wall of China is not one big wall, but it is made of many walls, So, Technically the Great Walls of China, at least 16 of them were built over 2,400 years ago in China by the successive emperors and dynasties. The total length of the Great Wall of China is spread over the 21,000km. It is the distance longer than the distance between the two poles of the earth.
The idea behind the construction of the Great Wall of China is to keep uncouth marauding neighbors from the north, that is, Scots, Mongols. So how do they propose new numbers? Technology is like this: GPS, satellite imagery, 3D models, laser scanning, aerial mapping, and drones. Helicopter drone has become an important tool for making such TV documentaries. They have infused new energy into the ancient people in a very modern way. These drones are good. They have five webcams and some map stuff - you can fly along the walls and they're back, everything you need to know. It also takes a lot of martial arts, full of drama and exaggeration. This is "the most distinctive engineering feat in history"; "one of the major man-made structures on earth"; they are using "breakthrough science" and "cutting chemistry" to unravel the mystical core of "the greatest structures in the world." Anyway, there is always a huge structure there. Basically, it's awesome. If the Great Wall of China is a creature swimming in the sea, it will become a great white shark, an APEX
predator. You can also enjoy the Great Wall hiking and for this, you will be needed hiking shoes. So what else did they find out and then use all their groundbreaking science, technology, and deciphering? They have a sophisticated signaling system, early semaphores in China, to alert attacks. The red flag on the pole means that 50 Xiongnu came. Three red flags. 200 Xiongnu came. Big bonfire? 1000 Xiongnu came, and so on. The Huns have long been scary - the early Scots, basically.
Dr. Xiang, a professor of advanced chemistry and an expert on ancient building materials, took samples of the Ming Dynasty wall built by the Mongols who occupied China for more than 100 years and was eventually sent to packing. He discovered that the secret of wall strength and longevity lies not in bricks, but in a mortar. The white color of the mortar is legendary because it is made of artificial bone. Cheung said that is not the case. Into the secret ingredients of mortar, maintaining the world's greatest structure for hundreds of years. It is “sticky rice”. Isn’t that great to know that rice we eat, were used at that time as glue for pasting such a great walls together? In many modern buildings of the houses, some people add sticky rice is the construction and it will last forever. The Great Wall is the best place for enjoying the vacation with family and with friends. If you go with kids they learn many things and discover a new story about the Great Wall of China. You can enjoy the sightseeing, camping (at some places) and Great Wall hiking.
