The book of Richard Halliburton, an adventurer from America in 1938 entitled “Second Book of Marvels” made people more believe that the Great Wall of China could really be seen from the space. The earliest evidence was written by an antique stuffs collector from England, named William Stukeley in 1754 which compared the Great Wall of China and Hadrian Wall in England by stating that Hadrian Wall could only be defeated by the great wall of China, which was the most important building in the world, so that it could be seen from the moon. Even, it is written in the China school book. Perception about the great wall which was seen from the space already became a myth. The first China astronaut who went to the space in 2004, Yang Li-wei, also stated that he couldn’t see that building.

According to the count, the overall length reached 8,850 km. The result of the research showed that the great wall was longer than what is already known. In 2009, the department of survey and mapping and the department of culture treasure of China conducted a research to recount the length of the great wall.
