Starting at Shanhai Pass in the east and ending up at Jiayu Pass in the west, the Great Wall traverses up and down over numerous mountains and valleys in five of China’s northern provinces and two autonomous regions. As it extends over a distance of more than 6000 kms, it is called in Chinese the Wanmlichangcheng which means “Ten Thousand Li Long Wall”. It is a symbol of intelligence of the working people of old days, and also one of the great architectural miracles in the world.
Construction of the wall first began in the 7th century B.C. after Qin Shi Huang, the first emperor of the Qin Dynasty (221—206BC) achieved the unification of China in 221 B.C... He had the fortification walls of the three kingdoms Qin, Zhao and Yan linked up to be a continuous wall extending more than ten thousand li (a li = 1/2 kms), which formed the essential size of the present-day Great Wall. Since then the later dynasties continued to repair and build the wall. The great wall as it stands today was restored and reinforced during the Ming Dynasty.
The great Wall winds like a giant serpent along the lofty myriad mountains. It is one of the most famous attractions to visitors.
