答案

The Great Wall of China is a Chinese fortification built from the 5th century BC until the beginning of the 17th century,in order to protect the various dynasties from raids by Hunnic,Mongol,Turkic,and other nomadic tribes coming from areas in modern-day Mongolia and Manchuria.Several walls,also referred to as the Great Wall of China,were built since the 5th century BC,the most famous being the one built between 220 BC and 200 BC by the first Emperor of China,Qin Shi Huang; this wall was located much further north than the current wall built during the Ming Dynasty,and little of it remains.
The Great Wall of China was originally a project of Qin dynasty designed to keep out the nomadic Xiongnu invaders from the north.Some of the wall was built during the Qin,but most of it that we see today was constructed during the Ming dynasty.
The Great Wall is the world's longest man-made structure,stretching over a formidable 6,352 km (3,948 miles),from Shanhai Pass on the Bohai Sea in the east,at the limit between "China proper" and Manchuria (Northeast China),to Lop Nur in the southeastern portion of Xinjiang Uygur Autonomous Region .Along most of its arc,it roughly delineates the border between North China and Inner Mongolia.See List of largest buildings in the world
Great Wall is all the Chinese pride!
