This video contains information about great wall of china.
The Great Wall of China simplified Chinese, is a series of fortifications that were built across the historical northern borders of ancient Chinese states and Imperial China as protection against various nomadic groups from the Eurasian Steppe. Several walls were built from as early as the 7th century BC, with selective stretches later joined together by Qin Shi Huang, the first emperor of China. Little of the Qin wall remains. Later on, many successive dynasties built and maintained multiple stretches of border walls. The most well-known sections of the wall were built by the Ming dynasty (thirteen hundred sixty eight to sixteen hundred forty four).
The notion that the wall can be seen from the moon is a well-known but untrue myth
