The Great Wall of China was built, in part, to define the boundary of the Mongol Empire.

The wall was built to protect China from its enemies and invaders from the North, especially the Mongols who were invading China on a regular basis. They were a tribal group that eventually conquered China. The wall was a military defense line, it connected the beacon towers, fortresses and strategic passes together.

Most of the current Great Wall seen today was built in the Ming Dynasty ( 1368- 1644) and it is approximately 6000 km long.

The answer is to depend the boundary of the Mongol empire.
