The construction of the Great Wall was going on in the following centuries, for the northern nomadic peoples constantly harried the inner land.

Most succeeding dynasties, like Han, Sui, Northern and Jin dynasties all made great efforts to repair, rebuild, or expand sections of the Great Wall.

In the Han Dynasty (206 B.C–1644 B.C.), the Emperor Hanwudi built the Great Wall for many times, to protect the region of Hetao and Longxi from the northern invasion. In addition, a separate outer wall was constructed north of the Yinshan range which went to ruin through years of neglect. At that time, the total length for the Great Wall comes to more than 10,000 kilometers.

Most of the ancient walls have eroded away over the centuries, and very few sections remain today. The most extensive reinforcements and renovations were carried out in the Ming Dynasty (1368–1644) when altogether 18 stretches were reinforced with bricks and rocks. That is to say, today’s Great Wall is shaped in the Ming dynasty.
