Taxonomy is the science of classifying organisms. The system currently used by taxonomists is called the Linnaean taxonomic system, in honor of Swedish biologist Carolus Linnaeus (1707 â 1778). The Linnaean system breaks down organisms into seven major divisions, called taxa (singular: taxon).
When used by the Chinese to protect their land, this section of the wall has had many guards to defend China's capita, Beijing. Made of stone and bricks from the hills, this portion of the Great Wall is 7.8 meters (25.6 ft) high and 5 meters (16.4 ft) wide.
So I will give you the official length. The Great Wall of China is much longer than what has been commonly accepted as fact. The length of the wall was previously thought to be 8850 kilometers or 5500 miles. The actual length, however, is 21,196.18 kilometers. How many miles long is the Great Wall of China? An unbelievable 13,170 miles.
