Name source of the Great Wall

Introduction of Name source of the Great Wall
Great Wall of China is also called "Wan Li Chang Cheng" in Chinese or "the long wall of 10,000 li" in English.

In early days, many a great wall had been built -- north, east, west and south -- over the vast territory of China. Each stretches several hundreds kilometers in length. The Chinese name "Chang Cheng" or long wall came into existence because of its length. Chang Cheng (Great Wall in Chinese), which extends through North China, is very magnificent. As the Great Wall was reconstructed --in Qin, Han and Ming Dynasties -- its length exceeded 5,000 km(10,000 li). Hence the name "Wan Li Chang Cheng" or "the long wall of 10,000 li". Actually, the long wall of 10,000 li is more than its stated length. The Great Wall reconstructed during the Ming Dynasty alone exceeds 7,300 km in length. Most of the ruined silos of the Ming built wall remain to this day.
