Chinese Pinyin: Cháng Chéng/Wàn Lǐ Cháng Chéng

Enjoying the fame of "Wan Li Chang Cheng", Great Wall starts from Hushan in Liaoning in the east and ends at Jiayuguan Pass in Gansu in the west, via the nine provinces or cities in northern China, including Liaoning, Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Inner Mongolia, Ningxia and Gansu. It is often compared to a huge dragon winding up and down in the mountains, grassland and deserts. In Chinese history, over 20 states and dynasties have built the wall, and the sections built in Qin (221 BC-206 BC), Han (206BC-220) and Ming (1368-1644) dynasties exceed 10,000 Li (about 3,107 miles). The new survey of the length of the wall in Ming Dynasty has confirmed that  it is 8,851.8 km (5,500 miles) long.

At present, the Great Wall has already lost its military function, and many sections have been repaired and opened to the public. Among them, Badaling is the most famous which receives the most visitors from home and abroad. Mutianyu is famous for its spectacular scenery, Jinshanling and Simatai are well known for the wildness and cragginess, and Jiankou is attracted by its dangerous location. Due to these varieties, it's no wonder that Great Wall is the most welcomed scenic sight in China.
