秦长城

Unlike the earlier Qin fortifications, the Ming construction was stronger and more elaborate due to the use of bricks and stone instead of rammed earth.

由于使用砖石及石头代替夯土，与早期秦长城相比，明长城更为坚固，技术更为复杂。

In China, there have been a three peaks of the Great Wall built, namely, the Qin Great Wall, Han Great Wall, Ming Great Wall.

而我国曾经出现了三个修筑长城的高峰，分别是秦长城，汉长城，明长城。

Now north the Shanxi Datong, places such as Gansu Min county west end have the Qin Great Wallruins.

今山西大同北部，甘肃岷县城西等地均有秦长城遗址。
