Does Great Wall of China run along all China?

The Great Wall of China does not run along all of China. It is a series of fortifications that were built over many centuries by various dynasties and states that existed in China. The wall stretches for about 6,350 kilometers (3,945 miles) from the eastern province of Liaoning to the western province of Gansu. It is not a single, continuous wall, but rather a series of connected sections that were built at different times and for different purposes.
